Energy saving lights aim to reduce the amount of electricity it takes to light a building. Energy saving lights have recently become more popular as households are more intent on recycling and reducing costs. An energy saving light bulb generates invisible ultraviolet light that excites a fluorescent coating, known as phosphor, on the inside of the tube, which then emits visible light. CFLs (Compact Fluorescent Lamps) need slightly more energy when they are initially turned on, but once the electricity starts moving, the CFL uses about 70% less energy than an incandescent bulbs.

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.
