LED
 
White LED technology can provide both long life and energy efficiency. Figures vary from one manufacturer to another but the best quality devices now provide more than100 Lumens per Watt and will last between 50,000 and 100,000 hours (until the output has reached 70%). Life expectancy is reduced with higher ambient temperatures.

 

Fluorescent
Still one of the most efficient light sources available, fluorescent tubes produce up to 90 Lumens per Watt and they are much cheaper to produce than LED’s. They have a life span of about 10,000 hours (until light output has reached 80%) although this is reduced by frequent switching.

 

Halogen
A form of Tungsten lighting, Halogen bulbs are less efficient then LED or Fluorescent, producing only 20 Lumens per Watt. They are however, much cheaper to make and do not require any circuitry to operate from a low voltage supply. The life span is also less at about 1000 hours until failure so bulb changing is more frequent.
