Why LED Lighting?
LED lights last up to 50 times longer than a standard Halogen light globe. At 45,000 hours you only need to change the globes once every 30 years.
LED lights run on 90% less energy than standard halogen lights, and with up to 50% of a electricity bill comprising of lighting, thats a huge saving over a year.
LEDs produce more light per watt than incandescent bulbs.
LEDs can emit light of an intended color without the use of color filters that traditional lighting methods require. This is more efficient and will lower ongoing costs.
LEDs can be very small (smaller than 2 mm2) and are easily populated onto printed circuit boards.
On / Off Time
LEDs light up very quickly.
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. They are a perfect match with movement sensors.
LEDs attracts almost no insects. Most insects are actually attracted to the ultraviolet rays (light with a wavelength of between 400 and 320 nanometers) emitted by conventional light sources. Conveniently, LEDs for standard residential applications just happen to emit almost no light in this ranges.
LEDs can very easily be dimmed either by Pulse-width modulation or lowering the forward current.
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.
LEDs mostly fail by dimming over time, rather than the abrupt burn-out of incandescent bulbs.
LEDs can have a long useful life. LED life is approx. 35,000 to 50,000 hours of useful life, though time to complete failure may be longer. 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 1,000–2,000 hours.
LEDs, being solid state components, are difficult to damage with external shock, unlike fluorescent and incandescent bulbs which are fragile.
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.
LEDs do not contain mercury, unlike fluorescent lamps.
