PAR LED lamps use this same design but, instead of halogen bulbs, use energy-efficient light emitting diodes. All PAR LED lights will be listed with a number after them, such as PAR LED 20. The number refers to the diameter of the base. To calculate the diameter, you should divide the number by 8.

Ed Miliband has recently defended his leadership of the Labour party asserting that he has a “very clear plan” for the coming years.
