At present, LED light and compact fluorescent light and not much difference between the luminous efficiency of LED, with the increase of CREE.

3, this year may be light output of 186lm/w light source, high power LED lamp is still a straw hat or piranha type LED; LED lighting lamp using high-power LED as light source, the price is higher; and the straw hat lamp or piranha type LED price is very cheap, not suitable for the light source lighting lamp level.

4, driving power, good driving power can guarantee the integral lamp life, theory of life of LED is 100 thousand hours and the general driving power of life less than 100 thousand hours; to ensure the life of lamps, driving power supply is a key ring; on the other hand, LED must be a constant current driver, if the constant pressure and low cost the drive will shorten the service life of LED.
