A smart ceiling fan light kit can mean a replacement light for an existing fan—or a complete fan and lighting system with app control. That distinction shapes this roundup: the Govee 52-inch fan is the broadest all-in-one choice, while the 7-inch Ledytech retrofit adds smart color and voice features to a compatible existing fixture. For smaller installations, the QiyuanLS two-pack takes a different route by combining a screw-in fan and light for compact spaces.

My ranking weighs fit and installation type first, then lighting usefulness, smart control, and the compromises each option brings. The main tradeoff is between a straightforward, bright replacement light and richer connected features: TobeBright prioritizes high light output with selectable white tones, while Ledytech adds RGB and app control but requires wired installation and cannot use an external dimmer or smart switch. I also include a complete fan because some shoppers need airflow and lighting together, not just a retrofit light.
Complete the kit
Key Takeaways
- Best all-in-one system: Govee combines a 52-inch fan, reversible DC motor, RGBWW main light, ambient backlight, and Matter support, but it is a full fan replacement rather than a light-only retrofit.
- Best smart retrofit for a larger opening: Ledytech’s 7-inch kit offers 1,800 lumens, adjustable white light, RGB, app control, and voice compatibility; check the opening and wiring before buying.
- Best for brightness and simple white-light choices: TobeBright provides up to 3,200 lumens and three selectable color temperatures, but lacks the app, voice, and color effects found on Ledytech.
- Best compact fan-and-light add-on: QiyuanLS screws into an E26/E27 socket and includes two units, though its compact format is not a substitute for a full-size room fan.
- Choose the right installation type first: The two Ledytech kits and TobeBright are retrofit light modules, QiyuanLS is a socket-mounted fan-light, and Govee replaces the entire fan assembly.

More Details on Our Top Picks
Govee 52-Inch Smart Ceiling Fan with RGBIC Lights and Remote
For someone who wants airflow, room lighting, and connected controls in one purchase, Govee is the most capable all-in-one pick here. Its 52-inch flush-mount fan is a full fixture rather than a light module for an existing fan, so it sits at the top because it covers the broadest smart fan-light use case—not because it is the easiest retrofit. The RGBWW main light is meant to handle functional illumination, while the separate RGBICWW backlight adds a decorative layer. That division is more useful than relying on color effects alone for everyday lighting.
Compared with the Ledytech retrofit kits, Govee brings actual fan performance, six speeds, reversible airflow, and a stated maximum of 5,000 CFM. It also offers a wider lighting temperature range, from 1,000K to 10,000K, and Matter compatibility alongside app, remote, and voice controls. Those capabilities make it the strongest choice when replacing the entire ceiling fan. The tradeoff is scope: a buyer who only needs a new light module will be paying in effort and complexity for a fan replacement they may not need.
The reversible DC motor and specified low-noise operation add practical seasonal and nighttime flexibility, while the flush-mount design suits rooms where a hanging fixture is undesirable. I would still verify ceiling dimensions and installation requirements before choosing it. The product notes recommend the latest app version for minimum fan speed and Matter connectivity, and mention possible communication error alerts. Compared with a simpler remote-only installation like QiyuanLS, Govee offers a much more connected system but depends more heavily on its app and network setup.
My ranking places it first for buyers who want a modern fan-and-light replacement with broad smart-home support. It is not the best match for someone searching narrowly for an inexpensive-to-install bulb-style accessory, or for a room where an existing fan should stay in place. Think of it as a complete smart ceiling fan solution that happens to address the same upgrade need as retrofit kits, rather than as a drop-in light-only kit.
Pros:- Combines a 52-inch fan with a functional main light and separate ambient RGBICWW backlight.
- Matter-certified connectivity works alongside app, remote, and voice controls.
- Six speeds, reversible airflow, and a DC motor support everyday and seasonal use.
- Specified airflow reaches 5,000 CFM, giving it a broader fan role than the retrofit options.
Cons:- Replaces the complete fan, so it is not a direct light-kit upgrade for an existing fan.
- Minimum-speed and Matter features depend on the recommended current app version.
- Product details note occasional communication error alerts.
Best for: Buyers replacing a full ceiling fan who want app, remote, voice, and Matter control plus both functional and ambient lighting.
Not ideal for: Shoppers who only need to replace an existing fan’s light module, or who want a minimal socket-in installation.
- Fan size:52 inches
- Mounting:Flush mount
- Maximum airflow:5,000 CFM
- Motor and speeds:Reversible DC motor; 6 speeds
- Main light output:Up to 2,800 lumens
- Lighting:RGBWW main light and RGBICWW ambient backlight
- Color temperature:1,000K–10,000K
- Connectivity and control:Matter; app, remote, Alexa, Google Assistant, and SmartThings
Our verdict“Choose Govee when you want to replace the entire fan with a connected lighting and airflow system, not when you only need a retrofit light.”
Ledytech Smart RGB Ceiling Light Retrofit Kit, 1800 Lumens, 7-Inch
Among the actual light retrofits, I rank this 7-inch Ledytech first for shoppers who want a brighter smart upgrade and whose fan can accept its size. It produces up to 1,800 lumens from an 18-watt LED, with tunable white from 2,700K to 6,500K, RGB colors, and dimming from 5% to 100%. App, remote, Alexa, and Google Assistant controls give it more flexibility than TobeBright, which focuses on bright white light and compatible dimmers rather than app-based color control.
The size and output distinguish it from the 5.5-inch Ledytech sibling, which tops out at 1,200 lumens. If the existing opening fits seven inches and the room benefits from additional light, the larger kit is the more capable of the two. It also offers scenes, music synchronization, and timers, giving it a more entertainment-oriented profile than TobeBright’s three fixed white-temperature selections. The RGB effects can be useful for accents or mood settings, but they are not a replacement for choosing a comfortable white tone for regular tasks.
There is a meaningful installation catch: this is a wired 120-volt retrofit, not a screw-in accessory. It also cannot be used with external dimmers or smart switches, so buyers should plan to use its supplied remote, app, or supported voice controls rather than trying to keep an existing wall dimmer in the circuit. That limitation is more restrictive than TobeBright’s specified compatibility with suitable LED dimmers, though TobeBright does not provide the same smart color and voice feature set.
I would put this kit ahead of the smaller Ledytech only when its footprint and brighter output suit the fixture. If a fan has a smaller light compartment, the 5.5-inch version is the safer direction; if the priority is maximum stated brightness and simple selectable white light, TobeBright is the stronger alternative. The 7-inch Ledytech makes most sense as a smart, color-capable retrofit for a verified compatible fixture and a buyer willing to handle wiring.
Pros:- Up to 1,800 lumens gives it more stated output than the smaller Ledytech retrofit.
- Offers adjustable white light, RGB colors, and dimming from 5% to 100%.
- App, remote, Alexa, and Google Assistant controls support several ways to adjust the light.
- Includes scene, music-sync, and timer features for more than basic on-off operation.
Cons:- Requires 120-volt wiring and a compatible 7-inch installation space.
- Does not work with external dimmers or smart switches.
- Color effects and app features may be unnecessary for buyers who only need bright white light.
Best for: Owners of compatible ceiling fans with a 7-inch light opening who want app, voice, RGB, and tunable-white control.
Not ideal for: Anyone who needs a screw-in solution, has a smaller light opening, or plans to keep an external dimmer or smart switch.
- Brand and model:Ledytech XGD-NZ-002
- Size:7 inches
- Wattage and output:18 watts; up to 1,800 lumens
- White color range:2,700K–6,500K
- Color and dimming:RGB; 5%–100%
- Voltage:120 volts
- Controls:App, remote, Alexa, and Google Assistant
- Connectivity and use:Wi-Fi; indoor
Our verdict“This is my preferred Ledytech retrofit when a verified 7-inch fit and smart color control matter more than simple dimmer compatibility.”
TobeBright 36W Dimmable Ceiling Fan LED Light Replacement, 6.69-Inch, 3200 Lumens, 3 Color Temperatures
TobeBright is the straightforward choice when the goal is strong, adjustable white illumination, not a connected lighting ecosystem. Its stated 3,200 lumens are the highest light output among the retrofit modules in this lineup, and its 6.69-inch size sits between the two Ledytech formats. Buyers can select 3,000K, 4,000K, or 5,000K, then dim from 10% to 100% with a compatible LED dimmer. Compared with Ledytech, it gives up RGB, app, voice, music sync, and scenes; in exchange, its purpose is easier to understand: brighten a compatible fixture and choose among three white tones.
This can suit a room where a low-output fan light needs a more substantial functional upgrade. The three selectable color temperatures let a buyer move between warmer and cooler white without relying on RGB settings. Its dimming starts at 10%, rather than Ledytech’s specified 5%, and depends on a compatible LED dimmer. That makes the wall control a potential advantage for people who already have a suitable dimmer, but a limitation for anyone expecting built-in app or voice operation. Check the dimmer model and fixture before assuming compatibility.
Fit is the key issue. The 6.69-inch diameter should be compared with the existing light compartment, and the unit is not water resistant, so it belongs indoors. The product description also notes that replacing a T9 fluorescent bulb requires removing the ballast. That is a different installation task from simply replacing an LED module, and it should be factored into the decision. By contrast, Ledytech offers richer smart features but also requires wiring and excludes external dimmers and smart switches.
I place TobeBright below the Ledytech smart retrofit because this roundup centers on smart kits, and TobeBright does not list app, Wi-Fi, or voice control. It remains a compelling functional-light alternative when brightness and ordinary dimming matter more than connected control. Choose it for a confirmed 6.69-inch fit and compatible LED dimmer; skip it if color effects, remote app access, or smart-home routines are part of the brief.
Pros:- Up to 3,200 lumens is the highest stated output among the retrofit light modules here.
- Three white color temperatures cover warm, neutral, and cooler lighting preferences.
- Dimming from 10% to 100% is supported with compatible LED dimmers.
- The 6.69-inch format is a distinct middle-size option between the Ledytech kits.
Cons:- No app, voice, or Wi-Fi control is specified.
- The fixture opening and compatible dimmer must be checked before purchase.
- A T9 fluorescent replacement requires ballast removal, and the unit is not water resistant.
Best for: Buyers who want a bright retrofit light with three white settings and can use a compatible LED dimmer.
Not ideal for: Shoppers looking for Wi-Fi, app, voice, RGB, or a retrofit that avoids checking fixture and dimmer compatibility.
- Diameter:6.69 inches
- Wattage and output:36 watts; up to 3,200 lumens
- Color temperatures:3,000K, 4,000K, and 5,000K
- Dimming range:10%–100% with compatible LED dimmers
- Voltage:120–130 volts
- Mounting:Ceiling mount
- Water resistance:Not water resistant
- Package quantity:1
Our verdict“Pick TobeBright for high-output white light and compatible dimmer control, not for smart-home features or RGB effects.”
Ledytech Smart RGB Ceiling Light Retrofit Kit, 1200 Lumens, 12W, 5.5-Inch
The smaller Ledytech carries the same basic smart-light appeal as the 7-inch model in a more compact 5.5-inch format. It offers adjustable white light from 2,700K to 6,500K, 16 million RGB colors, dimming from 5% to 100%, and app, remote, Alexa, and Google Assistant control. The lower maximum output—1,200 lumens rather than the larger sibling’s 1,800—makes this the more sensible pick when size is the deciding factor and the room does not need the brighter option.
Compared with TobeBright, this kit sacrifices stated lumen output but adds Wi-Fi-based app control, voice operation, music sync, and customizable scenes. Those features can give an existing fan light more flexible color and scheduling options; they matter less if the light will mostly stay on one white setting. The remote is useful alongside the app, since everyday operation does not have to depend on opening a phone or using a voice assistant.
It uses 120-volt wiring and can be installed with magnets or screws according to the supplied description. That makes it unlike QiyuanLS, which screws into a standard E26/E27 socket and also supplies fan blades. The Ledytech is a light retrofit, not a way to add a fan to a socket. Before choosing it, measure the opening and confirm the existing fan’s construction can accommodate the mounting method. It also cannot be paired with an external dimmer or smart switch, so existing wall controls may need attention.
I rank the 5.5-inch version below the 7-inch Ledytech because it provides less stated output, but its smaller footprint gives it a clear place in the lineup. It is the better choice when a seven-inch module would not fit and smart color features remain important. For a large room or a buyer who primarily wants maximum functional brightness, TobeBright’s higher output is the more direct alternative; for a compact smart lighting upgrade, this Ledytech is the stronger match.
Pros:- Compact 5.5-inch format may fit where the larger Ledytech module will not.
- Offers tunable white from 2,700K to 6,500K plus 16 million RGB colors.
- App, remote, Alexa, and Google Assistant controls give it flexible operation.
- Music synchronization, scenes, and 5%–100% dimming extend beyond basic light replacement.
Cons:- Its maximum output of 1,200 lumens is lower than the 7-inch Ledytech and TobeBright.
- Wired installation is required, and fixture fit must be confirmed.
- Not compatible with external dimmers or smart switches.
Best for: Owners of compatible smaller fan-light compartments who want RGB, tunable white, app control, and voice support.
Not ideal for: Buyers who need the brightest retrofit light, want to keep an external dimmer, or prefer a socket-in installation without wiring.
- Brand and model:Ledytech XGD-NZ-001
- Size:5.5 inches
- Wattage and output:12 watts; up to 1,200 lumens
- White color range:2,700K–6,500K
- Colors and dimming:16 million RGB colors; 5%–100%
- Voltage and use:120 volts; indoor
- Controls:App, remote, Alexa, and Google Assistant
- Connectivity:Wi-Fi
Our verdict“Choose the 5.5-inch Ledytech when its smaller footprint fits your fan and smart color control matters more than maximum brightness.”
QiyuanLS 2-Pack Socket Fan Light with Remote
QiyuanLS is the odd one out in a useful way: it is not a retrofit LED plate for an existing fan, but a screw-in fan-and-light unit for a standard E26/E27 socket. The two-pack includes a remote for fan speed, lighting, and timer control. Each unit offers four fan speeds, dimmable LED light, three color modes spanning 3,000K to 6,500K, and 1-, 2-, 4-, or 8-hour timer settings. That format can solve a small-space lighting and air-movement need with less fixture replacement work than Govee’s full 52-inch fan.
The comparison to Govee is about scale. Govee is built as a full ceiling fan, with a stated 5,000 CFM maximum airflow, six speeds, and reversible operation. QiyuanLS is described for compact spaces and does not list the same room-scale airflow details or seasonal reversal. It is also less connected than the Ledytech retrofit kits: control is by remote and button rather than app, Wi-Fi, Alexa, or Google Assistant. The payoff is a simpler socket-based approach where a matching standard socket is available.
Its two-unit package can be helpful when more than one compact area needs a fan-light, but buyers should not assume that a pair substitutes for a conventional fan in a larger room. The listed 30-watt power and plastic construction also signal a different use case from a fixed, full-size ceiling fan. Check the socket orientation, available clearance, and intended room before installing. Product information specifies indoor use, so this is not an option for exposed outdoor areas or damp locations.
I rank QiyuanLS fifth because it brings less smart-home integration than the other lighting-focused picks and does not serve the same job as a full fan. It still earns a distinct place for someone who wants compact airflow and light from a standard socket without wiring a new retrofit module. Skip it if you need strong whole-room airflow, Matter or voice control, or a replacement light for a fan that is already installed.
Pros:- Combines a fan and dimmable LED light in a screw-in E26/E27 format.
- Includes two units, each with four fan speeds and remote control.
- Three light color modes span 3,000K to 6,500K.
- Timer options of 1, 2, 4, or 8 hours add simple scheduled shutoff.
Cons:- Designed for compact spaces rather than full-room fan performance.
- No app, Wi-Fi, voice assistant, or Matter control is specified.
- Indoor-only use and socket fit limit where it can be installed.
Best for: People outfitting compact indoor spaces with standard E26/E27 sockets who want a remote-controlled fan and light in a two-pack.
Not ideal for: Buyers seeking a full-size ceiling fan, app or voice control, outdoor use, or a replacement light module for an existing fan.
- Quantity:2-pack
- Mounting:Screw-in E26/E27 socket
- Fan:5 blades; 4 speeds
- Lighting:Dimmable LED with 3 color modes
- Color temperature:3,000K–6,500K
- Timer:1, 2, 4, or 8 hours
- Power and voltage:30 watts; 110 volts
- Controls and use:Remote and button control; indoor
Our verdict“QiyuanLS is a niche pick for compact socket-based fan-light use, not a substitute for a connected retrofit or full-size ceiling fan.”
How We Picked
I ranked these options for the specific job implied by smart ceiling fan light kits: upgrading the light or fan-light function with better control, useful illumination, or both. Since the products span three installation styles, I did not treat their headline features as directly interchangeable. A retrofit module has to fit an existing fan and wiring; a socket unit has different expectations for airflow and scale; a complete fan is a larger replacement project.
My first filter was what the buyer is actually replacing. I then compared stated brightness, white-light adjustment, color effects, dimming, controls, and smart-home compatibility. I gave credit for remote operation where it makes a kit usable without a phone, and for voice or platform support where those functions are specified. Practical fit and restrictions matter just as much: a product that needs wiring, a particular socket, a matching opening, or a compatible dimmer can be a poor pick for the wrong room even when its feature list looks strong.
The ranking favors options with a clear role and a useful balance of fit, control, and lighting. Govee leads for buyers seeking a complete smart fan and light, not because it is the closest retrofit. Ledytech’s larger model ranks ahead of its smaller sibling for its higher stated output, while TobeBright is the value-oriented functional-light choice in this comparison. QiyuanLS fills a niche for compact socket installations. I have not assumed that a listed compatibility or lumen figure guarantees a result in every room; fixture dimensions, existing wiring, and the installation instructions still govern suitability.

Factors to Consider When Choosing Smart Ceiling Fan Light Kits
Before comparing app features or color modes, I would decide what kind of product the room needs. The five options here are not interchangeable: three replace a light module, one screws into a standard socket and adds a small fan, and one replaces the whole ceiling fan. Once that distinction is clear, the remaining choices—fit, brightness, controls, and dimming—are easier to judge.Start with retrofit, socket, or full fan
A retrofit light module is the closest match if the fan itself works and only its light needs upgrading. The two Ledytech models and TobeBright fall into this group, but their diameters differ, so measure the existing opening and compare it with the product dimensions. Also check how the module attaches and what wiring it expects. Ledytech describes magnet or screw mounting and wired installation; TobeBright lists a ceiling-mount format and notes ballast removal for a T9 fluorescent replacement.
QiyuanLS is a different choice altogether: it screws into an E26/E27 socket and combines a compact fan with a light. It is not a replacement light for an existing ceiling fan. Govee goes further in the other direction, replacing the complete fan with a 52-inch flush-mount fixture. If keeping your current fan is a requirement, Govee is the wrong category even though it is the broadest smart system in this roundup.
Match brightness and color to the room
For the retrofit modules, compare stated light output with the room’s existing needs rather than assuming that more features mean more useful illumination. TobeBright lists up to 3,200 lumens, making it the brightest retrofit on paper. The 7-inch Ledytech lists 1,800 lumens, and the 5.5-inch model lists 1,200. These figures can help separate candidates, but actual comfort depends on fixture position, room size, and the existing shade or diffuser.
White-light choices differ too. TobeBright offers three set points—3,000K, 4,000K, and 5,000K—while Ledytech allows adjustment from 2,700K to 6,500K and adds RGB. Govee has a much wider stated white range and separate ambient color lighting. I would favor tunable white if the room shifts between relaxing and task use; choose RGB primarily if accent color, scenes, or entertainment effects are part of the plan.
Choose controls that fit your habits
Smart controls are useful only if they fit the way the household operates the light. Both Ledytech kits specify app, remote, Alexa, and Google Assistant control, along with Wi-Fi. Govee adds Matter and lists app, remote, voice, and SmartThings options. These systems suit buyers who want to adjust settings remotely or connect the fixture to a wider smart-home setup. Check that the controls and platform you use are included in the product information before choosing.
TobeBright is the simpler option: dimming requires a compatible LED dimmer, and no app or voice features are listed. That may be preferable when familiar wall control matters more than connected functions. QiyuanLS uses a remote and button controls, covering its fan, light, and timer without a listed app. Also pay attention to control restrictions: Ledytech explicitly excludes external dimmers and smart switches, so an existing wall control may not suit the kit.
Treat dimming and installation as compatibility questions
A dimming range is not enough by itself; the control method has to match the light. Ledytech specifies 5%–100% dimming through its smart controls and warns against external dimmers or smart switches. TobeBright specifies 10%–100% dimming with a compatible LED dimmer. QiyuanLS describes dimmable lighting controlled with its remote and button. Before buying, identify whether you intend to use a wall dimmer, supplied remote, app, or voice control—and do not assume these methods can be mixed.
For wired products, switch off power and follow the manufacturer’s installation instructions; consult a qualified electrician if the wiring or fixture is unfamiliar. Confirm the existing fan’s mounting arrangement and available space rather than relying on diameter alone. For TobeBright, check both the fixture opening and dimmer compatibility, and account for ballast removal if replacing a T9 fluorescent bulb. The socket-based QiyuanLS avoids the same retrofit process but only works where a suitable E26/E27 socket and enough clearance are present.
Consider whether the fan itself needs replacing
If airflow, seasonal reversal, and fan speeds are part of the upgrade, a light-only kit will not address them. Govee is the only full-size fan in this group, with six speeds, reversible airflow, and a stated 5,000 CFM maximum. QiyuanLS adds fan movement in a compact socket format, but it is intended for smaller spaces and should not be treated as a direct peer for a conventional room fan.
My practical decision rule is simple: keep a working fan and choose a matching retrofit if lighting is the only problem; select QiyuanLS for a compact socket application; choose Govee when the fan and light both need replacing. That prevents smart features from distracting from the main job the product has to do.
Frequently Asked Questions
Are these products all replacement light kits for existing ceiling fans?
No. The Ledytech 5.5-inch and 7-inch models and TobeBright are light retrofit options intended for compatible fixtures. QiyuanLS screws into an E26/E27 socket and adds a compact fan as well as a light. Govee is a complete 52-inch ceiling fan with lighting, so it replaces the whole fan rather than only its light module. I would identify the installation category first, then check dimensions and wiring.
Which option provides the most light?
Among the light retrofit modules, TobeBright has the highest stated output at up to 3,200 lumens. The 7-inch Ledytech lists up to 1,800 lumens, and the 5.5-inch Ledytech lists up to 1,200 lumens. Govee lists a main light output of up to 2,800 lumens, but it is a complete fan rather than a retrofit module. A room’s layout, fixture position, and diffuser can affect how bright these figures feel in practice.
Can I use a wall dimmer with either Ledytech retrofit?
The product details say that neither Ledytech retrofit is compatible with external dimmers or smart switches. Their dimming functions are intended to be used through the listed controls, including the app and remote, with voice control also specified. TobeBright takes a different approach and supports dimming with a compatible LED dimmer. Check the actual wall control and fixture setup before purchasing rather than assuming a dimming feature will work with any switch.
Which option is best if I want voice or smart-home control?
Both Ledytech kits list Wi-Fi, app control, Alexa, and Google Assistant support. Govee offers app, remote, Alexa, Google Assistant, SmartThings, and Matter-certified connectivity, making it the broadest listed smart-home option here. TobeBright and QiyuanLS do not list app or voice assistant control; TobeBright uses a compatible LED dimmer, while QiyuanLS relies on a remote and button controls. Check platform compatibility for your own setup before deciding.
How do I know whether a retrofit kit will fit my fan?
Measure the existing light opening and compare it with the kit’s stated size: the Ledytech models are 5.5 and 7 inches, and TobeBright is 6.69 inches. Diameter alone may not settle compatibility, since mounting, wiring, fixture construction, and clearance also matter. Review the installation details for the exact model, including TobeBright’s ballast-removal note for T9 fluorescent replacements. If the fan’s construction or wiring is unclear, ask a qualified electrician or the manufacturer before installation.
Conclusion
My recommendations depend on what you are replacing. Choose Govee if you want a complete smart fan and light with airflow, ambient color lighting, and Matter support. For a compatible existing fan and a preference for bright, practical white light, TobeBright has the highest stated retrofit output, provided you have a suitable LED dimmer and the dimensions fit.
If smart color and voice features matter more than wall-dimmer compatibility, choose the 7-inch Ledytech for its higher output or the 5.5-inch Ledytech when the smaller format is the deciding factor. Pick QiyuanLS for compact spaces with a standard E26/E27 socket where a remote-controlled fan and light are wanted together. In every case, verify installation type, opening or socket, and control compatibility before buying; the right choice is the one that fits the fixture and solves the room’s actual lighting or airflow problem.
