Energy Efficiency - LEDs (or Light Emitting Diodes) are up to 90% more energy efficient than conventional lighting sources. LEDs are also more directional, making it possible to efficiently direct and focus the light, achieving useful illumination with far few lumens, and much less energy wasted
Environmentally Friendly - LEDs do not contain hazardous mercury, unlike CFLs (compact fluorescent lamps)
Long Lifespan - Conventional lighting lasts from 1,000-10,000 hours, while quality LED lighting will last 50,000 to 100,000 hours (that's 17-34 years at 8 hrs/day!)
Color and Color Rendering Capabilities - LEDs can emit light of any color without the use of color filters (gels) that traditional lighting methods require (assuming proper controls). With recent technological advances, LED lighting has been inching up the CRI range
Durability - LEDs contain no moving parts or fragile filaments. Being that they're solid state components, they are difficult to damage with external shock.
Application / Design Flexibility - A single LED is relatively small in comparison to other light sources
Low Heat - LEDs radiate very little heat, which helps to maintain temperature control in and around lit areas.
No UV Emissions - LEDs produce no UV radiation, making them ideal for illuminating UV sensitive items on display, such as antiques, works of art, jewelry, etc.
Cycling / On/Off Time - LEDs light up very quickly and are ideal for use in applications that are subject to frequent on/off cycling, unlike fluorescent lamps for example, which tend to burn out more quickly when cycled frequently, or HID lamps that have a significant warm-up time.
Wide Selection of Products / Uses - LED products have followed the rapid technology advances of the computer industry, and now LEDs are available for almost any application you can imagine, including white LEDs for general illumination, spot lighting, wall wash lighting, submersible lighting, cove lighting, rope lighting, flex neon, retrofit lamps, displays, exterior/outdoor areas, pool/spa lighting, pond/fountain lighting, marine lighting, video tube lighting, dance floors, architectural lighting, club/restaurant lighting, and event lighting, to name a few.
