why LED?
Basic advantages of LED Light
​
-
Energy efficient – LED’s are now capable of outputting 135 lumens/watt
-
Long Lifetime – 30,000 hours or more if properly engineered
-
Rugged – LED’s are also called “Solid State Lighting (SSL) as they are made of solid material with no filament or tube or bulb to break
-
No warm-up period – LED’s light instantly – in nanoseconds
-
Not affected by cold temperatures – LED’s “like” low temperatures and will startup even in subzero weather
-
Directional – With LED’s you can direct the light where you want it, thus no light is wasted
-
Excellent Color Rendering – LED’s do not wash out colors like other light sources such as fluorescents, making them perfect for displays and retail applications
-
Environmentally friendly – LED’s contain no mercury or other hazardous substances
-
Controllable – LED’s can be controlled for brightness and color
Why LED’s are chosen for many applications
​
-
LEDs are ideal for use in applications that are subject to frequent on-off cycling, unlike fluorescent lamps that burn out more quickly when cycled frequently, or HID lamps that require a long time before restarting.
-
LEDs can very easily be dimmed or strobed
-
LEDs light up very quickly. A typical red indicator LED will achieve full brightness in microseconds.
-
LEDs mostly fail by dimming over time, rather than the abrupt burn-out of incandescent bulbs
-
LEDs, being solid state components, are difficult to damage with external shock, unlike fluorescent and incandescent bulbs which are fragile.
-
LEDs can be very small and are easily populated onto printed circuit boards.
-
LEDs do not contain mercury, unlike compact fluorescent lamps
