This light source is LED with the following advantages:
1. Efficiency: LEDs emit more lumens per watt than incandescent
light bulbs. The efficiency of LED lighting fixtures is not
affected by shape and size, unlike fluorescent light bulbs or
2. 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.
3. Slow failure: LEDs mostly fail by dimming over time, rather than
the abrupt failure of incandescent bulbs.
4. Lifetime: LEDs can have a relatively long useful life. One
report estimates 35,000 to 50,000 hours of useful life, though time
to complete failure may be longer.
5. Shock resistance: LEDs, being solid-state components, are
difficult to damage with external shock, unlike fluorescent and
incandescent bulbs, which are fragile.
6. Focus: The solid package of the LED can be designed to focus its
light. Incandescent and fluorescent sources often require an
external reflector to collect light and direct it in a usable
