LED Retrofit
Definition
The process of replacing older, less-efficient commercial lighting (fluorescent, metal halide, incandescent, HID) with LED (light-emitting diode) fixtures or lamp replacements. LED technology uses 50–75% less energy than fluorescent and 80–90% less than incandescent lighting.
Why It Matters for Your Business
LED retrofits deliver some of the fastest paybacks in commercial energy efficiency — often 1–3 years before incentives, and under 1 year with utility rebates and Section 179D deductions. They also reduce cooling load (less waste heat), improve light quality, and cut maintenance costs with 50,000+ hour lifespans.
Frequently Asked Questions
What rebates are available for LED retrofits?
Most utilities offer prescriptive rebates for commercial LED upgrades — typically $20–$100 per fixture. Programs vary by utility. The DSIRE database (dsireusa.org) lists current state and utility incentive programs.
Does Section 179D cover LED retrofits?
Yes. Qualified lighting improvements are one of the three eligible categories under Section 179D. The lighting subsystem deduction requires meeting ASHRAE 90.1 lighting power density reductions.
