Fluorescent light bulbs
They are the most common source used in commercial buildings, producing about two-thirds of our nation's illumination. Fluorescent bulbs are easily distinguished by their tubular design. They come in circular, straight or bent in a "U" shapes.
Fluorescent lamps are a good retrofit for incandescent light bulbs that operate a significant number of hours. Circular fluorescent bulbs can be used where exposed socket incandescent bulbs are currently used. Compact or PL fluorescent bulbs (available in 5-40 watts) can be substituted for many incandescent bulb types and will fit in many different lighting fixtures.
Facilities already using fluorescent bulbs should consider high efficiency fluorescent designs. They produce about the same amount of light, while saving about 10 to 15% of the energy usage. |
