Hisoo 2 Pack LED Light Engine Retrofit Kit
The Hisoo kit provides three color temperatures (3000K, 4000K, 5000K) and dimming from 5% to 100%. It’s designed for ceiling fans, pendants, and lanterns, with two installation methods—center-screw or magnet-based mounting. Best for multi-fixture use and for buyers who want precise color temperature control before installation. Caution: verify your dimmer compatibility since some older dimmers may not smoothly dim to very low levels.
Ledytech LED Ceiling Fan Light Retrofit Kit, 4 Inch
The Ledytech kit offers 3CCT switching (3000K, 4000K, 5000K) via a toggle switch and delivers 2200 lumens with CRI90. It is designed for direct retrofit into ceiling fan housings or standard ceiling lights, with plug-and-play wiring and 120V operation. Best for quick upgrades where a slim, panel-style light is desired. Caution: ensure your fixture can accommodate a 4-inch panel and confirm the plug-and-play adapter matches your existing wiring.
Legental 3″ LED Light Engine Retrofit Kit
The Legental kit uses a compact 3″ PCB within a 4.04″ overall size and outputs 750 lumens at 2700K, with CRI90 and dimmable operation at 120V. Best for compact flush mounts and small fixtures where space is limited. Limitation: lower brightness compared with larger kits, which may be less ideal for high-traffic living areas or rooms needing strong illumination.
Lustaled 2Pack 36W LED Light Engine Retrofit Kit
The Lustaled kit provides about 3200 lumens with 3CCT options (3000K, 4000K, 5000K) and 10-100% dimming. It targets larger ceiling fans and flush fixtures, offering robust brightness and broad diffusion. Best for bright living spaces or commercial areas where a high light output is needed. Caution: some users may prefer lower brightness for intimate settings; verify dimming range with your dimmer before purchase.
Buying Guide
What should you check before buying a retro kit?
- Fixture compatibility: Confirm the kit size (diameter/depth) fits your fixture housing and mounting style.
- Voltage and dimming: Ensure your home uses 120V and that your dimmer supports LED loads at the kit’s dimming range.
- Color temperature needs: If you want flexible ambiance, choose 3CCT kits; for consistent lighting, fixed temperature kits may suffice.
- CRI and diffusion: Higher CRI (CRI90) helps color accuracy; panel designs with even diffusion reduce glare and shadows.
- Installation method: Decide between plug-and-play and fixed mounting based on your wiring comfort level and fixture type.
Tips for a smooth upgrade
- Turn off power at the breaker during installation to ensure safety.
- Test dimming at various levels after installation to confirm compatibility with your existing dimmer switch.
- Plan color temperatures by room use: 2700K for cozy spaces, 4000K for work areas, 5000K for task lighting.
