What does Triphosphor mean?

Definition of triphosphate : a salt or acid that contains three phosphate groups — compare atp, gtp.

What colors do fluorescents emit?

Traditional tubular fluorescent lights are higher, around 5000K, meaning they give off a white light with a blue tint. Early CFLs were like that, but as noted above, consumers complained. Now CFLs are available with color temperatures around 2700K, about the same as incandescent.

What is Halo phosphor?

A wide variety of different whites can be created by the halophosphate system. The phosphor is in fact a blend of two different materials which radiate broadly in the blue and orange parts of the spectrum respectively. By changing the ratio of the two components a full range of warm to cool white hues can be achieved.

What is SP41?

Manufacturer: “This F15T8/SP41 is a fluorescent lamp that uses 15 watts. It has a T8 lamp shape, and a G13 base. It has a 4100K color temperature, and a color rendering index of 75. The bulb has 940 initial lumens, and an average rated life of 7500 hours.”

What is the phosphor in fluorescent lights?

In a fluorescent lamp, the emitted light is generated by a phosphor layer which is deposited on the inner side of a glass tube. The phosphor is excited by ultraviolet light, which is typically generated with a gas discharge in low-pressure mercury vapor….

Which of the following has best lamp efficiency?

Detailed Solution. A graphene LED light bulb is simply an LED light bulb where the filament has been coated in graphene. A graphene LED bulb is reported to be 10% more efficient than regular LED light bulbs.

Can flourescent bulbs be warm?

Fluorescent lights do not get as warm as their incandescent counterparts. Fluorescent lights never get hot, but a small amount of heat energy is created when keeping a fluorescent light on.

Is phosphor and phosphorus same?

As nouns the difference between phosphor and phosphorus is that phosphor is (chemistry) any of various compounds of transition metals or of rare earths that exhibits phosphorescence while phosphorus is (chemistry) a chemical element (symbol p) with an atomic number of 15, that exists in several allotropic forms.

What are inorganic phosphors?

Inorganic phosphors normally consist of a crystalline host material doped with a relatively small amount of rare earth or transition metal ions, called activators, which convert light from shorter wavelength to longer wavelength (Stokes shift) via electronic transitions.

Are F40 and T12 the same?

A T12 is 12/8ths of an inch, or 1.5″ in diameter. A T5 is 5/8″ in diameter. All F32 and F40 lamps are essentially 4 foot long lamps (47″ if you don’t count the pins). The FR71T12 is actually a 71″ long x 1.5″ diameter lamp that can handle from 80-120w and is typically run at 100w.
