Light-emitting diodes (LEDs) have been around for nearly 50 years, but because of the sharp price drop, they have become popular in the past 10 years.
Here are 4 main reasons why LED emergency lights are better:
Efficiency-LEDs use a process called electroluminescence, which means that electrons will combine with electron holes when they are turned on. The filament of an incandescent light bulb burns to produce light, which means that energy is used to generate heat. No filament is used in the LED, so heat is not a major issue. LEDs are thinner and lighter, which makes them more cost-effective. Low temperature performance, digital control capabilities and the rugged nature of the bulb make LED lamps more efficient than other lamps. Overall, LED lamps can usually save 30% energy compared to ordinary bulbs.
Lifetime-The lifespan of LED bulbs is about 50... less
