The payback math
A 4,000 sq ft office running 280 hours/month at 1.2 W/sq ft fluorescent vs 0.55 W/sq ft LED saves about $1,300/year at 2026 commercial rates. With a $5,500 retrofit and a Dominion rebate, payback is 2.8–3.5 years.
What's included
- 2x4 LED flat panels replacing fluorescent troffers
- Occupancy sensors zoned per office and conference room
- Daylight harvesting in perimeter offices
- 0–10V dimming for conference and breakroom
Light quality wins
- Uniform 4000K color (vs aged fluorescent yellow-green drift)
- Instant on, no warmup
- No flicker, no ballast hum
- Same lumens at lower wattage
