Buying Guide: Key Considerations For LED Retrofit Kits
- Fixture compatibility: Confirm if your fixtures are 1×2 or 2×4 and whether magnets can securely attach to your lamp housing.
- Lumen output and efficiency: Compare lumens and lm/W to ensure the kit meets your brightness needs while maximizing energy savings.
- Electrical requirements: Check voltage range (commonly 100-277V) and whether 0-10V dimming is supported if dimming is desired.
- Heat management and safety: Look for aluminum backs and flame-retardant materials that reduce heat buildup and fire risk.
- Installation complexity: Tool-free magnet mounting offers faster upgrades; ensure your fixtures are iron-based for magnets to work effectively.
- Longevity and maintenance: Prioritize kits with longer-rated lifespans and clear installation manuals to minimize future maintenance.
