While the precise wattage of a fluorescent light fixture depends on its design, fluorescent lights generally use around 25 percent as much energy as a comparable incandescent bulb. This is due to the fact that fluorescent fixtures produce far less heat, allowing them to convert more energy into visible light.Know More
Incandescent bulbs produce light by feeding current through a resistor wire, usually made of tungsten. As the current flows through the wire, it heats up and begins to glow. Traditional incandescent bulbs only convert around 5 percent of the electricity that flows through the wire into light, and the rest is released as heat.
Fluorescent lights, on the other hand, have no filament resistor. Instead, the electric current excites mercury inside the bulb, vaporizing it and causing it to release ultraviolet photons. These photons interact with a phosphor coating on the inside of the bulb, producing light. Since less energy is converted to heat, a fluorescent lamp can produce the same light as an incandescent bulb while using a small fraction of the wattage.
Since the wattage of a bulb can be an imprecise way of measuring its light output, many manufacturers have taken to rating their bulbs by lumen output. A 60-watt incandescent, for instance, puts out around 800 lumens of light.Learn more about Lighting
If fluorescent light ballasts have gone bad, they might become dim, buzz, change color or go through fast blinking cycles. All parts of the light should be inspected for default before replacement. A multimeter can be used to make certain that it is indeed the ballast itself that has gone bad.Full Answer >

Disposing of fluorescent light bulbs is only dangerous if the bulbs are broken or not handled properly, according to Fox News. The small amount of mercury in a single fluorescent bulb is enough to pollute 6,000 gallons of water, which makes proper disposal essential.Full Answer >
To replace a fluorescent light ballast, take off the cover of the old ballast, cut out the wiring, unscrew the old ballast and attach the new ballast. Ballast replacement is a common solution to flickering or humming fluorescent lights.Full Answer >
