Efficiency - LEDs use a process called electroluminescence, which means electrons combine with electron holes when turned on. Incandescent light bulbs have a filament that burns to produce light, which means that energy is used to create heat. No filament is used in LEDs, so heat is not a major issue. LEDs are thinner and lighter, which makes them more economical and efficient. The bulb's low-temperature capabilities, digital control capabilities, and ruggedness make LED lights more efficient than other lights. Overall, LED lights typically use 30% less energy than regular light bulbs.
Lifespan – LED bulbs last approximately 50 times longer than standard incandescent bulbs. The filament that burns inside an incandescent bulb quickly wears out, causing the bulb to need to be replaced. LED lights have no burning filament, so they last about 50,000 hours longer than standard incandescent bulbs.
Brightness – Brightness is extremely important when it comes to emergency lights. Emergency lights are used to illuminate evacuation paths from a building in an emergency. LED lights are one of the brightest types of light bulbs. They are much brighter than incandescent bulbs of the same wattage. LED lights are the best choice for brightness among emergency lights.
Maintenance – All emergency lights require inspection and testing; LEDs are no exception. However, extended service life makes replacement less likely. The cost of constantly replacing non-LED light bulbs can be high. Emergency lights with LED bulbs can save your facility money in the long run.
