LED, which stands for “Light Emitting Diode,” is a modern lighting alternative to gaseous and filament based lighting technologies. For years they have been used only in low-intensity needs devices, though recent technological advances have allowed LEDs to evolve for more high-intensity uses. Devices ranging from flashlights to commercial lightboxes now employ LED technology. With cost continually dropping, LEDs stand to easily dominate the lighting market.

One major benefit of LED technology is its extreme energy efficiency. More lumens are produced, per watt consumed, than any alternative lighting source. Additionally, consumer products using LEDs are shrinking in size due to the exceptionally small physical footprint of these lights. This translates into both lower initial price and lower long term cost as both energy and raw material needs diminish.

One of the most cited benefits of LED use is their incredible longevity. Typically the lifespan of incandescent lights is between one and two thousand hours while fluorescent lighting sources last approximately ten to fifteen thousand hours. LEDs last between thirty-five and fifty thousand hours at peak performance with many lasting far beyond these specs. Some lights put into service during the 70’s and 80’s are reported to still be running strong.

Some of their other practical advantages include universal light intensity control, color changing capabilities, minimal heat production, no inherent toxic materials, and the absence of glass as safety feature.
