Circular Fluorescent Tubes - Fluorescent Light

What Does Luminosity Mean

Luminosity is the amount of light that a tube or lamp is able to put out and the area which it is going to be able to illuminate. Incandescent lamps are at a disadvantage here because they are often only able to turn about 2% of their power input into visible white light. Fluorescent lamps, on the other hand, are able to convert about 22% of the input to light. This means that they are more efficient.
The luminosity can vary based on the type of tube that you have. The rating that a lamp receives is based on the lumens after 100 hours of operation.
