Lamp kinds comprise:

Ballast: A ballast is an auxiliary piece of gear built to start and correctly restrain the flow of electricity to discharge light sources including fluorescent and high intensity discharge (HID) lamps. Some lamps need the ballast to get thermal protection.
fluorescent light: A tube coated with phosphor including low pressure mercury vapor that produces white light.
Halogen: Incandescent lamps containing halogen gases for example bromine or iodine, raising the effectiveness of the lamp versus an incandescent lamp that is simple.

Neon:
Light emitting diodes:

Compact fluorescent lamps: CFLs are made to replace incandescent lamps in new and existing facilities.
Measurement of photometry or light is usually concerned with the quantity of helpful light falling on the quantity of light appearing from a lamp or other source as well as a surface, as well as the colours that may be left via this light. The human eye reacts differently to light from various parts of the spectrum that is visible, so the luminosity function must be taken by photometric measurements into consideration when quantifying the number of helpful light.
