2. United States lighting energy policy - Wikipedia

   en.wikipedia.org/wiki/United_States_lighting...

   The Energy Policy Act of 2005 (Pub.L. 109-58) provided an energy-efficient commercial building tax reduction program for lighting systems that exceed code lighting. Based on estimates by the U.S. Department of Energy (DOE), lighting represents 40% of the electrical consumption in a commercial building, through the improvement of these systems ...

3. Gas-discharge lamp - Wikipedia

   en.wikipedia.org/wiki/Gas-discharge_lamp

   Germicidal lamps are simple low-pressure mercury vapor discharges in a fused quartz envelope. Gas-discharge lamps are a family of artificial light sources that generate light by sending an electric discharge through an ionized gas, a plasma . Typically, such lamps use a noble gas ( argon, neon, krypton, and xenon) or a mixture of these gases.
