LED bulbs, or Light Emitting Diode bulbs area semiconductor light source that emits light when activated. Under the influence of a power source, electrons are able to recombine with electron holes in the device, thus releasing energy in the form of photons. The colour of the light is determined by the by the energy band gap of the semiconductor. LED lights have a must longer lifespan than the more commonly used incandescent lamps and are more efficient than a fluorescent lamp. Due to this, the LED bulb is becoming more commonplace within the home, but unlike the usual energy saving lightbulbs, they don't require any warm up time.
