A compact fluorescent lamp is a phosphorous-coated glass tube containing argon gas and mercury vapor. Electricity sent via the tube excites the mercury, setting off a chemical response that creates ultraviolet (UV) light. The phosphorus coating inside the tube absorbs the UV gentle and emits visible mild. Mild-emitting diode bulbs include a chip of semiconducting materials, typically product of a mixture of aluminum, arsenic and gallium. When an electrical present passes to the chip, electrons transfer from the negative layer of the material toward the optimistic layer and launch energy in the form of photons. Mild-emitting diode bulbs are constructed so that the photons released are concentrated and directed outward to create steady, visible gentle. Based on the U.S. Division of Energy, compact fluorescent lamps and light-emitting diode bulbs use seventy five to eighty % less vitality than traditional incandescent EcoLight smart bulbs.
