Fluorescent lighting other than compact fluorescent bulbs

Fluorescent lighting other than compact fluorescent bulbs
  In fluorescent lamps, energy is converted to light by using an electric charge to "excite" gaseous atoms within a fluorescent tube. Common types are "cool white," "warm white," etc. Special energy efficient fluorescent lights have been developed that produce the same amount of light while consuming less energy. Note: for definition of compact fluorescent bulbs, go to compact fluorescent bulbs.
