Compact Fluorescent Light Compact Fluorescent Light

• Can save more than $40 in electricity costs over its lifetime

• Uses about 75% less energy than standard incandescent bulbs and lasts up to 10 times longer

• Produces about 75% less heat, so it's safer to operate and can cut energy costs associated with home cooling

Halogen LightingHalogen Lighting

• Lamp is kept brighter than incandescent bulbs.• Light is more similar to that of sunlight.• Bulbs burn whiter than incandescent bulbs.• Electricity heats this filament up to about 4,500 degrees

F (2,500 degrees Celsius). Just like any hot metal, the tungsten gets "white hot" at that heat and emits a great deal of visible light in a process called incandescence
