"If you're using T8 or T12 fluorescent lamps in your ceiling troffers, hard-wired LEDs are now an excellent alternative," says Power Smart's lighting guru Cristian Suvagau. "Not only do hard-wired LED alternatives to T8s and T12s offer energy savings, they also reduce maintenance costs because of an LED luminaire's long lifetime.
"When treated right, an LED luminaire can last 50,000 to 60,000 hours, compared to 20,000 hours for standard T12 and T8 replacement lamps."
According to Suvagau, switching ceiling troffers from T8 fluorescents to LEDs can result in energy savings of more than 40 per cent in a single application. The savings climb to roughly 50 per cent when a change is made from T12 fluorescents to LEDs. The only exception is T5 fluorescents: since they're not used in ceiling troffers, they can't be replaced with these LEDs.
Features, benefits and applications of LEDs in ceiling troffersSuvagau estimates that close to two billion fluorescent lamps are in use at any given time in North America, and are typically found in office buildings, schools and classrooms, hospitals and banks.
"The adoption potential for LEDs in ceiling troffers is tremendous," he says. "T12 fluorescent lamps are also slowly being phased out, so now is the right time for customers to consider LEDs as an alternative."
Energy savings aside, another benefit of LEDs for ceiling troffers is the easy installation. There's no need to open up the ceiling or cut drywall. A certified electrician should be able to install an LED into a ceiling troffer in a modular ceiling grid or surface-mounted fixture in less than 10 minutes.
Other benefits of LED ceiling troffers:
- They don't contain mercury.
- The modern aesthetic is appealing, suitable for new construction and renovations.
- They're designed to direct light more specifically to the task area.
- They work well with a variety of lighting controls, including dimmers, timers and occupancy sensors.
