Why LED Retrofits are a No-Brainer
Lighting typically accounts for 20-40% of a commercial building's electricity bill. Switching from fluorescent (T5/T8) or HID lamps to LED reduces this load by 50-80% while improving light quality.
Beyond energy, LEDs last 50,000+ hours compared to 10,000 hours for older bulbs, slashing maintenance costs—a factor this calculator treats as a bonus.
