Tiger Light : Future Cats Purr About LED Lights

Two tigers from the future have a few things to say about screwing in those LED lights to help make their lives possible 50 years in the future. Hear what they have to say about the "Tiger Lights" that you put in and how the lights you put in may be the ones that save their lives! Stop climate change, save a tiger.

Bengal Tiger via en.wikipedia.org/wiki/Bengal_tiger
The Bengal tiger (Panthera tigris tigris) is the most numerous tiger subspecies. Its populations have been estimated at 1,706–1,909 in India, 440 in Bangladesh, 163–253 in Nepal and 67–81 in Bhutan.[2][3][4][5] Since 2010, it has been classified as an endangered species by the IUCN. The total population is estimated at fewer than 2,500 individuals with a decreasing trend, and none of the Tiger Conservation Landscapes within the Bengal tiger's range is large enough to support an effective population size of 250 adult individuals.[1]
Bengal is traditionally fixed as the typical locality for the binomial Panthera tigris, to which the British taxonomist Pocock subordinated the Bengal tiger in 1929 under the trinomial Panthera tigris tigris.[6][7]
It is the national animal of both India and Bangladesh.[8]

L.E.D. Advantages : via en.wikipedia.org/wiki/L.E.D.
Efficiency: LEDs emit more lumens per watt than incandescent light bulbs.[117] The efficiency of LED lighting fixtures is not affected by shape and size, unlike fluorescent light bulbs or tubes.
Color: LEDs can emit light of an intended color without using any color filters as traditional lighting methods need. This is more efficient and can lower initial costs.
Size: LEDs can be very small (smaller than 2 mm2[118]) and are easily attached to printed circuit boards.
On/Off time: LEDs light up very quickly. A typical red indicator LED will achieve full brightness in under a microsecond.[119] LEDs used in communications devices can have even faster response times.
Cycling: LEDs are ideal for uses subject to frequent on-off cycling, unlike fluorescent lamps that fail faster when cycled often, or HID lamps that require a long time before restarting.
Dimming: LEDs can very easily be dimmed either by pulse-width modulation or lowering the forward current.[120] This pulse-width modulation is why LED lights viewed on camera, particularly headlights on cars, appear to be flashing or flickering. This is a type of stroboscopic effect.
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.
Slow failure: LEDs mostly fail by dimming over time, rather than the abrupt failure of incandescent bulbs.[58]
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.[121] Fluorescent tubes typically are rated at about 10,000 to 15,000 hours, depending partly on the conditions of use, and incandescent light bulbs at 1,000 to 2,000 hours. Several DOE demonstrations have shown that reduced maintenance costs from this extended lifetime, rather than energy savings, is the primary factor in determining the payback period for an LED product.[122]
Shock resistance: LEDs, being solid-state components, are difficult to damage with external shock, unlike fluorescent and incandescent bulbs, which are fragile.
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 manner. For larger LED packages total internal reflection (TIR) lenses are often used to the same effect. However, when large quantities of light are needed many light sources are usually deployed, which are difficult to focus or collimate towards the same target.
