Smart ceiling fan light kits cover two very different needs: replacing the light on a compatible fan, or adding smart lighting and fan functions where the existing setup allows it. My strongest picks depend on which job you need done. The Fandian Replacement LED Light Kit is the focused choice for owners of compatible Fandian retractable fans, while the Ledytech 7-inch, 1800-lumen kit offers the most light and broad app, remote, and voice control. For small rooms with an E26 or E27 socket, the QiyuanLS two-pack adds a compact fan as well as a dimmable light.

The central tradeoff is fit versus flexibility. Fandian is a replacement part with narrow fan compatibility; the Ledytech kits offer colorful smart lighting but require a suitable 120V light base and cannot be used with external dimmer or smart switches. QiyuanLS is not a conventional ceiling-fan light replacement at all: it is a screw-in fan-and-light unit for compact indoor spaces. I rank these options by how clearly they fit their intended installation, what control they offer, and how much a buyer must verify before ordering.
Complete the kit
Key Takeaways
- For a compatible Fandian retractable fan, the Fandian replacement kit is the most directly targeted option, but verify the fan’s LED light type before ordering.
- For brighter retrofit lighting, Ledytech’s 7-inch kit offers up to 1800 lumens; the 5.5-inch model tops out at 1200 lumens and may suit a smaller opening.
- For app and voice control, both Ledytech kits support Wi-Fi, Alexa, and Google Assistant, but neither works with an external dimmer or smart switch.
- For an E26/E27 socket and two compact rooms, QiyuanLS includes two screw-in units with fan speeds, dimmable light, adjustable color temperature, and timers.
- These are not interchangeable upgrades: check fan-specific compatibility, socket type, light-base dimensions, wiring, and existing switch controls before choosing.

More Details on Our Top Picks
Fandian Replacement LED Light Kit for 42-Inch Retractable Ceiling Fans
The Fandian Replacement LED Light Kit earns this role because it addresses the most direct fan-light repair job in this lineup: replacing the light on a compatible Fandian retractable ceiling fan. Rather than asking buyers to adapt a generic smart fixture, it is designed as a replacement kit for that brand’s fans. Its dimmable, seven-color lighting and app control add more flexibility than a basic replacement lamp, with separate Smart Lamp Pro and Smart Light Pro apps listed for iOS and Android.
Its advantage is also its main limitation. Unlike the Ledytech retrofit kits, this is not presented as a general-purpose light for a range of ceiling fixtures. And unlike QiyuanLS, it does not add a fan to a socket; it depends on an existing compatible retractable fan. That specificity may make it the cleanest match for a Fandian owner, but it makes the product a poor bet for anyone with another brand or an uncertain LED assembly.
Check the exact fan and LED light type before buying. The listing identifies 42-inch Fandian retractable fans, but the supplied information does not promise compatibility with every model in that family. App control provides useful dimming and color changes, though the details do not list voice-assistant support or the extensive scene functions found on Ledytech. I rank it ahead of broader retrofit lights only for the buyer whose existing fan matches; outside that narrow group, the Ledytech options are more flexible lighting upgrades.
Pros:- Designed as a replacement light kit for compatible Fandian retractable ceiling fans
- Dimmable lighting with seven color changes
- App control is listed for both iOS and Android
Cons:- Compatibility is limited to suitable Fandian retractable fans
- The existing fan’s LED light type must be checked before ordering
Best for: Owners of a compatible 42-inch Fandian retractable ceiling fan who need a replacement light and want app-based dimming and color changes.
Not ideal for: Buyers with another fan brand, a standard light socket, or uncertainty about their fan’s LED light type; the supplied details do not establish universal compatibility.
- Brand:Fandian
- Product type:Replacement LED light kit
- Compatibility:Compatible Fandian retractable ceiling fans; verify LED light type
- Fan size:42 inches
- Lighting:Dimmable; seven color changes
- iOS control:Smart Lamp Pro app
- Android control:Smart Light Pro app
Our verdict“I recommend this as the most direct smart replacement for a compatible Fandian fan, but not as a general retrofit kit.”
QiyuanLS 2-Pack Screw-In Ceiling Fan Lights with Remote
The QiyuanLS two-pack takes a different route from the other entries: each unit screws into a standard E26/E27 socket and combines a small five-blade fan with a dimmable LED light. That makes it the most practical choice here for buyers who want both airflow and lighting without installing a conventional ceiling fan. The included remote adjusts four fan speeds, brightness, three color temperatures, and a timer, so routine changes do not depend on using a phone app.
Compared with the Fandian replacement kit, QiyuanLS is less tied to a particular fan brand but still depends on a specific socket. Compared with Ledytech, it adds a physical fan, yet it does not offer the listed Wi-Fi, app, or voice-assistant controls. Its 19-inch diameter and indoor-only design also point toward compact rooms rather than broad coverage in a large living space. The two-pack can suit two small spaces, but it should not be mistaken for a full-size fan upgrade.
The 3000K–6500K range gives buyers a choice from warmer to cooler white light, and the 1-, 2-, 4-, and 8-hour timer settings make it easier to schedule a shutoff without leaving a light or fan running. The product description lists both remote and button control, although the supplied details do not establish smart-home integration. I rank it as a value-oriented functional pick for socket-based installations, not as the strongest smart-lighting option. Skip it if you need app or voice operation, outdoor use, or the circulation of a larger ceiling fan.
Pros:- Two screw-in fan-and-light units are included
- Fits standard E26/E27 sockets
- Remote adjusts four fan speeds, brightness, color temperature, and timer
- Offers three white-light color temperatures from 3000K to 6500K
Cons:- The 19-inch fan design is aimed at compact spaces, not broad room coverage
- Indoor use only
- The listed controls do not include app or voice-assistant operation
Best for: People furnishing compact indoor spaces with standard E26/E27 sockets who want a two-pack of combined fan-and-light units controlled by remote.
Not ideal for: Buyers seeking app or voice control, a full-size ceiling fan, outdoor equipment, or a replacement light matched to a specific retractable fan.
- Pack size:2
- Fan diameter:19 inches
- Blade design:Five blades
- Socket:E26/E27
- Fan speeds:Four
- Light color temperature:3000K–6500K
- Wattage and voltage:30 watts; 110 volts
- Timer settings:1, 2, 4, or 8 hours
- Control and use:Remote and button control; indoor use
Our verdict“I’d choose this two-pack for compact rooms with compatible sockets when remote control and an integrated fan matter more than app-based smart features.”
Ledytech Smart RGB LED Ceiling Light Retrofit Kit, 1200 Lumens, 2700K–6500K, Alexa and Google Assistant Compatible
The Ledytech 5.5-inch retrofit kit is the better choice for buyers whose main priority is smart lighting rather than adding or replacing a fan. It combines adjustable white light from 2700K to 6500K with RGB colors and dimming from 5% to 100%. Its app, remote, Alexa, and Google Assistant controls give it the broadest listed control options in the roundup, and customizable scenes provide a way to save preferred effects rather than changing settings from scratch.
Its most useful comparison is the larger Ledytech 7-inch model. The smaller unit is listed at up to 1200 lumens, while the larger version reaches 1800 lumens and uses an 18-watt light. If a buyer needs more output or has a larger compatible light base, the 7-inch kit is the stronger fit. The 5.5-inch model may make more sense where the opening is smaller or the room does not call for as much light, but the listing does not establish that it fits any particular fan housing. Buyers should check the light base and dimensions rather than assume that “retrofit” means universal ceiling-fan compatibility.
This is a smart ceiling light retrofit, not a fan kit. It does not provide fan blades, airflow, or fan-speed control, so it serves a different purpose from QiyuanLS and the Fandian replacement. Its 120V indoor installation also comes with an important switch limitation: it does not work with external dimmer or smart switches. Music synchronization uses a phone microphone, which may be less appealing to someone who expects built-in audio sensing. I rank it ahead of the 7-inch model for buyers prioritizing a smaller listed size and more modest maximum output, not for those seeking the brightest option.
Pros:- Adjustable white light from 2700K to 6500K plus RGB colors
- App, remote, Alexa, and Google Assistant controls
- Dimming from 5% to 100% with scene and music-sync modes
- Up to 1200 lumens in a listed 5.5-inch size
Cons:- Does not include or control a ceiling fan
- Not compatible with external dimmer switches or smart switches
- Music synchronization uses the phone microphone
Best for: Buyers seeking a compact, app- and voice-controlled indoor LED retrofit with adjustable white light, RGB color, and dimming.
Not ideal for: Anyone who needs a fan or fan-speed controls, has an external dimmer or smart switch, or cannot verify a compatible 120V light base.
- Model:XGD-NZ-001
- Light and power:LED; 12 watts
- Maximum output:1200 lumens
- Color temperature:2700K–6500K
- Color and dimming:RGB, up to 16 million colors; 5%–100%
- Connectivity and controls:Wi-Fi; app, remote, and voice
- Voice assistants:Alexa and Google Assistant
- Size and voltage:5.5 inches; 120 volts
- Use and warranty:Indoor; three-year warranty
Our verdict“I’d pick the 5.5-inch Ledytech for a compatible smaller retrofit opening when smart controls matter more than fan functions or maximum brightness.”
Ledytech Smart RGB LED Ceiling Light Retrofit Kit, 1800 Lumens, 7 Inch
The Ledytech 7-inch retrofit kit is my pick for buyers who want more light output from a smart indoor fixture. Its listed maximum of 1800 lumens is 600 lumens above the 5.5-inch Ledytech model, making this the stronger candidate when brightness is a priority and the light base can accept the larger size. Like its smaller sibling, it offers adjustable white light from 2700K to 6500K, RGB colors, 5%–100% dimming, Wi-Fi app control, a remote, and Alexa and Google Assistant support.
That extra output comes with a size tradeoff: this model is 7 inches across, compared with 5.5 inches for the 1200-lumen kit. I would not choose between them on brightness alone; the right opening and fixture matter first. Both Ledytech options share the same basic smart-light strengths and switch restrictions, so the smaller model may be a better fit when its dimensions meet the installation need. Neither one adds a fan. For a buyer who needs airflow as well as lighting, the QiyuanLS screw-in units serve a different job, while Fandian is the more relevant option for replacing a compatible fan’s existing light.
The magnetic attachment and wiring clip are listed as installation features, and the package includes a remote. It supports scenes, music synchronization, and timers, but the music feature relies on a phone microphone or app rather than a dedicated microphone in the fixture. The key limitation is shared with the smaller Ledytech: it is not compatible with external dimmer or smart switches and is designed for indoor 120V use. I rank it first among the two retrofit lights for buyers prioritizing output, while keeping it below fan-specific solutions for anyone whose actual goal is a fan-light replacement.
Pros:- Up to 1800 lumens, compared with 1200 lumens from the smaller Ledytech kit
- Adjustable white light, RGB colors, and dimming from 5% to 100%
- App, remote, Alexa, and Google Assistant controls
- Includes scene modes, music sync, timers, magnetic attachment, and wiring clip
Cons:- Does not provide airflow or fan-speed control
- Not compatible with external dimmer switches or smart switches
- The 7-inch size must suit the light base, and music sync uses a phone microphone or app
Best for: Buyers with a compatible 7-inch indoor light base who want the brighter of the two Ledytech smart retrofit kits and use app, remote, or voice controls.
Not ideal for: People who need a fan, have a smaller opening, use an external dimmer or smart switch, or want an outdoor-rated fixture.
- Model:XGD-NZ-002
- Power and output:18 watts; up to 1800 lumens
- Color temperature:2700K–6500K
- Color and dimming:16 million RGB colors; 5%–100%
- Size and voltage:7 inches; 120 volts
- Connectivity:Wi-Fi
- Controls:App, remote, and voice
- Voice assistants:Alexa and Google Assistant
- Use and warranty:Indoor; three-year warranty
Our verdict“I recommend this as the brighter Ledytech retrofit when a compatible 7-inch base and smart lighting—not fan control—are the buyer’s priorities.”
How We Picked
I ranked these products by how well each matches the distinct task implied by a smart ceiling fan light kit: replacing a fan’s light, retrofitting smart lighting, or adding a compact fan-and-light combination. Those tasks are not equivalent, so I do not treat a high lumen figure or a long list of controls as an automatic win. A product has to make sense for the buyer’s existing fan, socket, or light base.
Compatibility comes first. The Fandian kit is limited to compatible Fandian retractable ceiling fans, and its listing calls for checking the LED light type. QiyuanLS is designed to screw into standard E26/E27 sockets, while the Ledytech kits are indoor 120V retrofit lights that use a light base and cannot be paired with external dimmer or smart switches. These requirements shape who can actually use each option.
I then compared control methods and lighting range. App control matters when a buyer wants changes beyond a basic wall switch; voice support can add convenience, but it is only useful when the home’s setup and wiring are compatible. Brightness, color temperature, color effects, dimming, fan speeds, and timers serve different needs, so I weigh them against each product’s intended space rather than ranking the longest feature list first.
Finally, I considered installation scope and meaningful limitations. The QiyuanLS units are small and indoor-only; Ledytech’s music synchronization relies on a phone microphone, and its smart functions do not make it a fan replacement. The supplied product details do not establish universal fit, installation suitability for every fan, or performance in every room. I favor clear use cases and point out where a buyer should check measurements or electrical compatibility before purchasing.

Factors to Consider When Choosing Smart Ceiling Fan Light Kits
I would start by identifying what needs to change: the light on an existing fan, the room’s lighting, or both airflow and light in a socket-based fixture. This roundup includes products for all three situations, so a feature comparison only helps after the installation type is clear.Decide whether you need a fan replacement or a light retrofit
A fan-specific replacement light and a smart light retrofit solve different problems. Fandian is the only pick here explicitly designed as a replacement light kit for a named fan family. Ledytech’s kits offer smart lighting but do not add a fan or list fan-speed controls. QiyuanLS combines a small fan and light in one screw-in unit, but it is not a replacement assembly for a conventional ceiling fan. Start with the job rather than the word “smart”: replacing a fan’s light calls for a compatible part, while changing color or adding voice control points toward a retrofit light.
Check the physical and electrical fit before ordering
Compatibility is the first buying filter. For Fandian, confirm both the fan model and its LED light type; the product is not listed as universal. For QiyuanLS, confirm a standard E26/E27 socket and remember that its units are intended for indoor use. For either Ledytech light, check the listed size against the light base and verify the installation is appropriate for its 120V indoor design. The product details do not establish fit for every fan canopy or ceiling fixture, so do not infer compatibility from appearance alone. If existing wiring or the ceiling assembly is uncertain, get qualified help before installation.
Choose controls that match your home
The control methods differ sharply. Fandian uses a phone app for dimming and color changes. QiyuanLS lists a remote and button control for fan speed, light settings, and timers, but not Wi-Fi or voice assistants. Ledytech supports its app and remote alongside Alexa and Google Assistant, though both models exclude external dimmer and smart switches. A smart fixture may not respond as intended when its power is cut or altered by an incompatible wall control. Check the existing switch arrangement before choosing the more connected option.
Match brightness and color functions to the room
Among the Ledytech kits, the 7-inch model reaches 1800 lumens, while the 5.5-inch model reaches 1200 lumens. That makes the larger model the clearer choice when more stated output is needed, provided it fits. Both offer adjustable white temperature, RGB color, and wide-range dimming. QiyuanLS lists three color temperatures from 3000K to 6500K, which provides white-light adjustment without the listed RGB effects. Fandian offers dimming and seven color changes, but the supplied description does not list a lumen figure. Choose based on the light level and color range you actually need, rather than assuming every product’s “smart” features are alike.
Think about airflow and room scale
Only QiyuanLS in this set lists fan blades and multiple fan speeds. Its 19-inch diameter and compact-space positioning make it a different category from a full-size ceiling fan. Fandian is a light replacement for an existing 42-inch retractable fan, while Ledytech is lighting-only. If the room needs meaningful airflow from a conventional ceiling fan, none of these details supports treating the Ledytech kits as fan upgrades. Likewise, buyers wanting a replacement light for a retractable fan should not assume a screw-in fan bulb is equivalent to the original assembly.
Account for timers, scenes, and music synchronization
Feature extras can matter when they solve a routine task. QiyuanLS offers 1-, 2-, 4-, and 8-hour timers for its fan and light. Ledytech lists customizable scenes, timers, and music synchronization, which can add variety to ambient lighting. Its music feature uses the phone microphone or app, so the phone has to be part of that experience. Fandian’s supplied details focus on dimming, color changes, and app control rather than scenes or timers. Compare these extras with how you intend to use the fixture; a timer on a compact fan may be more useful than decorative effects, while scene control may matter more in a room used for entertainment.
Treat the installation notes as buying requirements
A feature list cannot replace an installation check. QiyuanLS is a screw-in product, but still requires the correct socket and indoor placement. Ledytech describes a 120V light-base installation with a wiring clip and, for the 7-inch version, magnetic attachment; it also explicitly rules out external dimmer and smart switches. Fandian’s replacement status does not guarantee compatibility with every Fandian light assembly. Before ordering, confirm the electrical supply, dimensions, control setup, and manufacturer compatibility. If any of those details do not match, another product in this roundup may be a better fit—or none may be appropriate for the installation.
Frequently Asked Questions
Which option is the best actual replacement light for a ceiling fan?
Fandian is the most directly targeted replacement in this roundup, but only for compatible Fandian retractable ceiling fans. The product information calls for checking the fan’s LED light type, so I would verify the exact model and assembly before ordering. The two Ledytech products are smart light retrofits rather than fan-specific replacement kits, and QiyuanLS is a screw-in fan-and-light unit.
Do the Ledytech retrofit kits include a ceiling fan?
No. The Ledytech 5.5-inch and 7-inch kits are LED ceiling-light retrofit kits; their descriptions do not list fan blades or fan-speed controls. They are the picks for app-controlled, dimmable white and RGB lighting. If you need both a compact fan and a light, QiyuanLS is the product in this group that combines those functions, while a compatible Fandian kit replaces the light on an existing fan.
Which Ledytech kit should I choose: 1200 or 1800 lumens?
Choose based on the light-base size and desired light output. The 5.5-inch model is listed at up to 1200 lumens, while the 7-inch model reaches up to 1800 lumens. The brighter model is a more suitable starting point when you want greater stated output and have a compatible 7-inch base; the smaller kit may fit a more limited opening. Neither listing establishes universal fit, so check dimensions and installation requirements before buying.
Can I use a Ledytech kit with an existing dimmer or smart wall switch?
The product details state that both Ledytech kits are not compatible with external dimmer or smart switches. Check the wall control and wiring arrangement before installation rather than assuming an app-controlled bulb will work with an existing dimmer. If your current setup relies on an incompatible control, resolve that issue before choosing a Ledytech retrofit or select a different product whose requirements fit the installation.
Does QiyuanLS offer app or voice control?
The supplied description lists remote and button control for the QiyuanLS units, including fan speed, brightness, color temperature, and timer settings. It does not list an app, Wi-Fi connection, Alexa, or Google Assistant support. Buyers who want those smart-home controls should compare the Ledytech kits, while remembering that those retrofit lights do not include a fan and have switch compatibility limits.
Conclusion
My recommendation depends on the fixture you already have. Choose Fandian if you own a compatible 42-inch Fandian retractable fan and have confirmed its LED light type; it is the most direct fan-light replacement here. Choose QiyuanLS if you need two compact indoor fan-and-light units for E26/E27 sockets and prefer a remote over app control. For a smart lighting retrofit, choose the 7-inch Ledytech when its base fits and higher stated output is useful; choose the 5.5-inch version when its smaller size and 1200-lumen maximum better suit the opening and room.
I would skip the Ledytech kits if your priority is airflow or if your setup depends on an external dimmer or smart switch. I would skip QiyuanLS if you need a full-size fan or voice integration, and skip Fandian if your fan is not confirmed compatible. These products serve distinct installation needs, so checking the fan model, socket or base size, wiring, and switch type is a better first step than comparing smart features alone.
