Lighting accounts for roughly 40 percent of energy consumption in many commercial buildings. Switching to energy-efficient lights can reduce lighting costs by as much as 75% each year. That is money back in YOUR pocket.
Fluorescent tube lights are more energy efficient that the popular A-type standard incandescent lamps, and will reduce energy consumption up to 40%. Fluorescent lights create less direct glare than incandescent lights have a cooler and quieter operation. Just as important, modern fluorescent bulbs do not flicker during start-up, making them perfect for commercial buildings.
When purchasing fluorescent lights, look for T8 high-efficiency one inch lamps, which have a low life-cycle cost and illumination that more closely resembles natural light. The T8 lights are smaller in diameter than the older T12 lights, which enable the gases and rare earth phosphors inside to function more efficiently.
LED lighting uses 75% less energy and will last 35 to 50 times longer than incandescent lights and 2 to 5 times longer than fluorescent lighting. They produce very little heat and will not break like traditional bulbs. LED lights that are Energy Star qualified even come with a minimum three year warranty, though in many instances they can last a decade or more. In terms of return on your investment, LED bulbs can represent huge savings despite their high up-front costs.
Don’t let the high prices of efficient bulbs scare you away though. You can reduce your upfront costs by switching out your old lights with one of these new types of energy efficient lighting as the old bulbs burn out. Eventually, you’ll have replaced every single bulb, and the savings will really start piling up.
