Led flood light fixture is rapidly replacing less efficient incandescent bulbs. Although flood fluorescent bulbs cost a little more to begin with, they are more efficient than incandescent flood lights and will save money in the long run. Like all fluorescent lamps, fluorescent light bulbs floods used a tube filled with argon gas and some mercury to produce light. At each end of the tube are electrical terminals.
When led flood light fixture is on, it sends electrons through the gas. When one of these electrons is a molecule of mercury, mercury absorbs the energy of the electron. The electron releases this energy as a photon of ultraviolet light.
The back led flood light fixture is a parabolic mirror. When photons of light hitting the mirror are reflected directly from the bulb. This creates a focused beam of light. Compact fluorescent lamps are much more efficient than, ordinary incandescent bulbs, using 50 to 80 percent less energy. Also they last much longer than incandescent bulbs, saving you money on replacement cost. Fluorescent bulbs contain mercury, which is toxic to humans. They must be handled carefully to avoid breaking and taken to a recycling center when burned.
