Buying Guide: Key Considerations For 277V LED Retrofit Kits
- Voltage compatibility: Most kits list 100-277V. Confirm your fixture’s ballast bypass requirements and verify that the kit is compatible with 277V circuits to avoid mismatches.
- Fixture type: Troffers vs. shoebox vs. strip retrofits have different mounting needs. Choose kits designed for your fixture type (2×2, 2×4, canopy, or shoebox).
- Brightness and efficiency: Look for lumens per watt and total lumens to ensure adequate coverage. Higher efficiency reduces running costs over time.
- Installation method: Magnetic mounting offers fast, tool-free upgrades but check compatibility with existing fixtures. Some kits require ballast bypass or wiring changes.
- Beam angle and color temperature: For outdoor areas, a broad 5000K daylight tone is common. Indoor spaces may benefit from warmer temperatures (3000K-4000K) depending on use.
- Safety certifications: ETL or UL listings indicate compliance with safety standards, particularly for outdoor or high-occupancy areas.
