Buying Guide: Key Considerations For T12 To LED Retrofits
- Fixture compatibility: Check fixture depth, ballast status, and whether the kit uses ballast bypass or ballast-compatible wiring.
- Brightness and efficiency: Look for lumens per watt (lm/W) and total lumen output to match your space’s needs.
- Installation method: Magnetic retrofit kits offer quick installs; ballast bypass kits require wiring changes—consider skill level and safety.
- Color temperature: Choose 4000K–5000K for general workspace tasks; 5000K–6500K for high-visibility environments like warehouses or garages.
- Lifespan and maintenance: Longer lifespans reduce replacement costs and downtime; verify 50,000+ hour expectations when available.
- Dimming and controls: If you need dimming, confirm 0-10V compatibility and any driver limitations.
- Size and form factor: Ensure the kit fits within the fixture cavity and aligns with existing mounting hardware.
- EMI considerations: Some tubes may affect radios or remote devices; consider placement and installation guidelines.
