How to choose a good LED corn lamp?
Current LED corn light fair ground are far quoted price of every trade, and they all said that their products have more than a lot of good, how to judge the quality of LED corn light as a layman?The LED corn lamp is based on several parameters:
1,Light decay. The better LED corn lamp declines by 30 per cent before 25,000 hours.The main factors that determine the light failure are the quality of the light source, the difference of the cooling structure.
Foreign original factory packaging of high power light source, such as CREE failure is better than domestic packaging, as amateur can't see the light source, simple way of judging the main is the price , foreign light source of the original light source is higher than domestic packaging price .
So if you want to buy a good quality LED corn lamp ,you have to provide the manufacturer information about light source.
2, light effect. Namely each watt of lumens, the unit LM/W, it is to reflect the energy-saving performance of the lamps and lanterns, better lamps and lanterns, its light effect is higher. As leds light effect improve, TEK LED corn light is likely to produce 130LM/W this year.
3, light source. LED corn lamp using large power LED as light source, the price is higher;
4,Power supply. A good driver power supply can guarantee the life of the whole lamp, LED has a theoretical life of 50,000 hours, but general power supply life is less than 50,000 hours.
In order to guarantee the life of whole lamp, the driving power supply is also a key link.On the other hand, leds have to be constant current drivers, and low cost constant pressure drives shorten the life of the LED.
How to choose a high quality LED corn light? That is consumers care about this problem, according to above several factors to choose can avoid buy inferior LED corn light, choose the right LED corn light.
