Fluorescent lighting is a compact light method which uses fluorescence to produce light that is visible. Fluorescent lamps operate via an electric current in the gas which stimulates a mercury vapor, that produces short-wave ultraviolet light. This triggers a phosphor coating on the inside of the bulb to glow with light waves that can exceed 100 lumens per watt. Because compact fluorescent lamps (or CFL) contain mercury, the UL certification requires recycling the lamps instead of just throwing them in the trash. However, when used in large numbers in the commercial industries, they can be disposed of in landfills because they do not poison the soil and the amount of mercury does not increase in waste streams. Fluorescent lamps are far more energy efficient than any other type of lighting methods. Their bulbs also last longer than any other bulbs, generally, between 10,000 to 20,000 hours. There are three main types of fluorescent lamps – cold cathode, hot cathode, and electroluminescent. They each use phosphors triggered by electrons to create light waves that are easy on the human eye.
Fluorescent Lamp Holders
There are many varying parts to fluorescent lighting fixtures. One such part or fixture is the Fluorescent Lamp Holder. The straight fluorescent lamps have two sets of electrodes at each end, which connects to the lamps via small metal prongs. In CFL’s the electrodes are hidden because they have the screw type base. The prongs in both styles fit into the Fluorescent Lamp Holder, either in a slide on or snap in mounting. The fluorescent lamp holders are available in various sizes, large, medium, and small. A Fluorescent Lamp Holder part is also designed for the straight bipin base bulb. The 12, 15, 24, and 48 inch straight fixtures are commonly used in homes and offices. The 4 foot (48″) and U shaped, circular types are probably the most widely used sizes. The latest advancement in the lamp holder models, are the T-8 and the T-5 adapters or conversion sets. They are UL and CSA approved, with an easy retro fitting conversion using existing socket plates. The T-8 and the T-5 conversions are designed with spring loaded features for positive lamp contact. These models are more commonly used for straight-in lamps with no turning required, plus they can be used with 18ga solid wire with 3/8 inch strip length.
