Q:How much time LED lamp life

LED the whole lamp life means establishing droop 30% of the time, the higher the temperature of the solder, the more serious the droop, at the same time because of the LED drive power components in the limited life (especially the electrolytic capacitors under high temperature electrolyte dry), so we all find balance in cooling costs and the temperature of lamps and lanterns

Q:Buy what good LED lamp? How to judge the quality of lamps and lanterns is good or bad

Droop, good LED lamps and lanterns in 25000 hours before the light failure < 30%; Decided to light the main factor of failure is the stand or fall of light source, heat dissipation structure difference; Foreign original factory packaging of high power light source, such as CREE light source the light of the light source of failure is better than that of domestic packaging, as amateur can't see the light source, simple way of judging the main is the price that foreign light source of the original light source is domestic packaging price much higher; So if you want to buy good quality LED lamps and lanterns must provide light source manufacturer information.

1, 35 w u shoot the light, power is far greater than 3 w LED lights, both the brightness of the more than 10 times of... Painted - 2, substitution, both the voltage must be consistent, otherwise (voltage is too low, or high) will be not bright, or burned failure. Painted - 3, "with variable pressure searcher don't have to change?" ...... See come out, the original 35 w shoot the light, is the low voltage power supply, LED lights also can, if the same voltage but LED3W brightness, is far less than 35 w.
