How to Distinguish the LED Light Quality as Layman

At present, there are a lot of different LED lamp quotation as the same light from the wholesales manufacture in the market, and the light suppliers keep saying that their product quality is the best one in the industry. As a layman, it is important to distinguish the LED light quality standard when you choose a LED light manufacture in long term cooperation. Actually, the quality depends on several parameters , such as light failure, luminous efficiency,light source,driving power,etc.

1, Light failure.

Usually, the LED lamps’ the light failure < 30% after 25000 hours; the main factor of light failure is the stand or fall of light source, and the difference of heat dissipation structure; the light failure of original high power light source from foreign is better than the domestic original, you may not find the the light source,and just simply judge it from its price. Actually, the foreign light source price is higher than domestic. The way to judge is that the LED light factory offer the light source manufacture’s information to prove.

2, Luminous Efficiency.

It means the number of lumens per watt, and unit is LM/W. It reflects the energy-saving performance of lamps and lanterns, power saving of lamps and lanterns, and the higher light efficiency.

3, Light Source.

The high power LED as light source for LED lamps. Usually, the price is higher; and straw hat lamp or piranha LED price is very cheap, which is not suitable for the light source of lamps and lanterns lighting level.   

4, Driving Power.

 Good driving power can guarantee the overall life of the lamps and lanterns. In theory, the LED life is 100000 hours and the normal drive power supply less than 100000 hours. In order to guarantee the overall life of the lamps and lanterns, driving power supply is also a key link;On the other hand, it must be LED constant current drive, if using a low-cost constant voltage driver , it will shorten the service life of the LED. As an ordinary consumers , how to identify the LED driver power supply of the good or bad? You also need to judge the light failure service life, light efficiency, and quality warranty period. The LED light manufactures is better, who dares to provide a long quality warranty period.
