What is a fluorescent backlight?
Fluorescent lighting is a highly versatile type of lighting that you most likely encounter at the office, school, or grocery store. It’s known for energy efficiency compared to incandescent and halogen light bulbs, and a lower price compared to LEDs.
Is fluorescent sustainable?
Compact Fluorescent Lamp Watt for watt, there’s no question whether or not CFLs save energy as compared to their predecessors. But with the concerns of toxic mercury and the recent developments in LED technology, CFLs may not be the smartest choice for long-term sustainability.
How many lumens is a fluorescent?
Well, fluorescent tubes can only produce about 50-100 lumens per watt (lm/w).
Is LED better than fluorescent?
LEDs are up to 50% more efficient than fluorescent lights – so they use less energy. Translation: Dramatically smaller electric bills. LEDs usually last at least twice as long as fluorescents, which means they need to be changed less often.
Are fluorescent lights still used?
Long life – Fluorescents last a long time, although not quite as long as LEDs. Widely used – Fluorescents are used in a variety of applications across multiple industries. Hotels, commercial office buildings, grocery stores, healthcare facilities, warehouses, parking garages, and more all use fluorescent lighting.
How energy efficient is a fluorescent light?
Fluorescent lighting is very energy efficient It uses around one fifth of the power used by incandescent lighting – an electric light with a wire filament heated until it glows. Typically, fluorescent bulbs last for 6000 to 8000 hours, whereas incandescent bulbs generally only last for around 1000 to 2000 hours.
How energy efficient are fluorescent?
Compact fluorescent lamps (CFLs) were the first energy efficient bulbs on the market and use around 70-80% less electricity than the equivalent traditional bulbs, as well as lasting almost 10 times longer.
What size is a T12?
1.5-inch
T12s are 1.5-inch diameter fluorescent tubes. These are the oldest of the fluorescent tubes and they almost always run off magnetic ballasts, which are no longer manufactured. Typically, you see T12s in troffers.
Are fluorescent lumens the same as LED lumens?
Lumens. Fluorescent lights produce between 50 and 100 lumens per watt. By comparison, LEDs can produce roughly 130 lumens per watt. For example, a T5HO Commercial LED tube light uses only 25 watts to produce an output of 3334 lumens.
What is the brightest fluorescent material?
Brightly fluorescent under ultraviolet light, tugtupite also exhibits tenebrescence. A zinc silicate, willemite is well known for its extremely bright green fluorescence, though it can fluoresce in other colors, as well.
Why do fluorescent tubes glow?
Every fluorescent tube is coated with phosphor powder. If you stuck your finger in the tube and rubbed the inside, it would look like you just enjoyed a powdered doughnut. This phosphor coating glows when it is excited by the invisible UV light, and that is what we see with our eyes – glowing phosphor powder which creates a “white light.”
How to choose the best fluorescent tube lighting for your project?
Determining the tube size of the fluorescent light will help you decide which tube lighting is a suitable replacement. The tube size will also be a clue on the best method for converting fluorescent tubes to LED.
What is the smallest fluorescent tube size?
T4 Fluorescent Lights T4 tubes are the smallest of the fluorescent bulb sizes, at only 4 eighths of an inch (0.5 in). Their size is what makes T4 lights popular for under cabinet lighting purposes and accent lighting for displays or a staircase. There is no industry standard for the length or wattage of T4 tube lights.
