What does phosphor coating do?
Phosphor layers provide most of the light produced by fluorescent lamps, and are also used to improve the balance of light produced by metal halide lamps. White LED lamps consist of a blue or ultra-violet emitter with a phosphor coating that emits at longer wavelengths, giving a full spectrum of visible light.
What is the phosphor in fluorescent lights?
The inner lining of fluorescent tubes are coated with phosphors, which absorb the ultraviolet light from electrically charged mercury vapor and re-emit visible light based on a mixt of blue, green and red emitters. The blue phosphor in current use is already low in rare-earth elements.
What is the main benefit of Triphosphor fluorescent lamps?
Answer: As the name implies three phosphors allow for better colour rendering as each one emits light mainly in one region of the light spectrum corresponding with a primary colour. The result is more realistic reproduction of colour making objects look more natural and people healthier!
What Triphosphor white?
Fluorescent Triphosphor Tubes T8 – White. A new generation of triphosphor coated fluorescent tubes. Using T8 triphosphor tubes in place of T12 and T8 halophosphor tubes. increases light levels and extends lamp life, up to 20000 hours. when used with electronic control gear, improves colour rendering.
Is Phosphorus an LED light?
LED Technology Blue phosphorus is the most commonly used type of light-emitting diode (LED). To produce white light (as an alternative to fluorescent light), blue phosphorus LEDs are used with energized yellow phosphorus.
What are the disadvantages of fluorescent lamps?
Disadvantages of Fluorescent Lighting
- Fluorescent lamps contain toxic materials.
- Frequent switching results in early failure.
- Light from fluorescent lamps is omnidirectional.
- Fluorescent lights emit ultraviolet light.
- Older fluorescents suffer brief warm-up period.
- Ballast or Buzz.
What is the normal life of a fluorescent lamp?

|---|---|
| Fluorescent | 24,000-36,000 hours |
| HID | 10,000-24,000 hours |
| Compact Fluorescent | |
| Plug-in | 10,000-20,000 hours |
What does Triphosphor mean?
: a salt or acid that contains three phosphate groups — compare atp, gtp.
Is warm white or cool white better?
While cool white look great in modern kitchens and where the brighter the better, warm white works much better where you are looking for softer light. It’s particularly well suited to lounges, living rooms and traditional kitchen, like country styles, where the white light contrasts too much with the rest of the room.
