Fluorescent light bulbs are filled with low-density, gaseous mercury. These When the gas reaches a certain energy level, it begins to give off photons at certain wavelengths that cause the lamp to produce visible light.Compared to traditional incandescent lamps, fluorescent light bulbs are more costly to purchase, but use electricity much more efficiently. Mercury doesn’t absorb into the skin easily, so don’t freak out if you accidentally touch it, but do avoid breathing the dust or vapors.
