Fluorescent lighting

Fluorescent lighting is a popular and efficient lighting system used globally. It is most commonly found in commercial facilities. Fluorescent lamps emit extremely bright glow without getting blistering hot like an ordinary light bulb. They are more efficient as compared to incandescent lamps. Fluorescent lamps and fixtures are certainly more expensive to install than incandescent lighting, but they are significantly cheaper to operate. Besides, the lamps last far longer than incandescent lamps, making the long term cost-of-operation for fluorescent lighting far less than incandescent lighting. Because of their versatility, fluorescent lamps are available in numerous sizes, types, shapes, colors and light intensity. Some are designed to operate in cold locations, while others generate large amounts of light at the expense of service life.
All fluorescent lamps grow dimmer with age, and they may even begin to flicker or flash on and off. These are warning signals, and we should make the necessary repairs as soon as we notice any change in the lamp's normal performance. A dim tube frequently requires replacement, and failure to replace it can strain other parts of the fixture. Also, repeated flickering or flashing will wear out the starter, causing the insulation at the starter to deteriorate.
