LED panels look better and save money. Flat Panels are LED lighting solutions that replace fluorescent lights in drop ceilings. Flat Panels are installed by removing the ceiling panel and wiring into the power source. They can be mounted in multiple ways depending on your needs including suspension-mounted and surface-mounted. Some advantages to having LEDs in drop ceiling lighting fixtures are that LEDs have lower Wattage for the same level of lumens (light) cast, they last longer (up to 50,000 hours of use, equaling several years), and they contain no mercury or other harmful substances.
