-
Efficiency: LEDs
produce more light per Watt than incandescent bulbs.
-
Color: LEDs
can emit light of an intended color without the use of colour
filters that traditional lighting methods require.
-
Size: LEDs
can be very small and are easily populated onto printed circuit
boards.
-
On/Off time: LEDs
light up very quickly, some achieve full brightness in microseconds.
-
Cycling: 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.
-
Dimming: LEDs
can be very easily be dimmed either by Pulse-width modulation
or lowering the forwar contrast.
-
Cool Light: in
contrast to most light sources, LEDs radiate very little heat
in the form of IR that can cause damage to sensitive objects
or fabrics. Wasted energy is dispersed as heat through the base
of the LED.
-
Lifetime: LEDs
have a relatively long useful life. One report estimates 35.000
ot 50.000 hours of useful life, though time to complete failure
may be longer, significantly lower replacement costs, and lower
energy cost.
-
Shock resistance:
LEDs, being solid state components, are difficult to damage
with external shock,unlike other bulbs which are fragile.
-
Toxicity: LEDs
do not contain mercury, unlike fluorescent lamps.
