the only thing i will say regarding lighting, LEDS are the most efficient light form there is. any other light their efficiency are not as much a most people think. a normal light bulb gives off 70.03% of its energy in heat, 1% in sound and 28.97% in light, so just remember that nearly 3/4 of the energy is lost in heat. just like to say i no this due to 4 years becoming an electrician
