Buying Guide
What should you consider when choosing a 17W LED ceiling fan light retrofit?
- Fixture compatibility: Measure the fixture’s space and verify the retrofit’s overall size (often 5.39″ for many kits). Confirm the socket type and voltage (usually 120V).
- Color temperature: Choose between warm (2700K), neutral/daylight (5000K) or adjustable (2700K–5000K) to match room mood and decor.
- Color Rendering Index (CRI): A higher CRI (CR I90) ensures colors appear natural under the light, beneficial for living areas and workspaces.
- Dimming: If you want dimming, ensure the kit supports TRIAC dimming or is compatible with your existing dimmer. Some kits require a separate dimmer purchase.
- Longevity and efficiency: Look for wattage around 17W and lumens around 1200–1644LM for a balanced bright, energy-efficient result.
- Model-specific fit: Some modules are designed for particular fan models (e.g., Merwry, Caprice). Check exact model compatibility to avoid installation issues.
- Certification and safety: Prefer kits with UL/JA8 certifications and trustworthy brands to ensure safe operation and compliance with electrical standards.
- Installation approach: Consider whether you need a compact, magnet-mounted solution for easier installation or a more traditional retrofit that requires wiring and setscrew alignment.
