LED floodlight manufacturers do not have fixed cooperation customers, all want to find good quality and cheap manufacturers to cooperate, but the quality is proportional to the price, why the same appearance and the same power of lamps and lanterns, different manufacturers price gap is very big, first of all from the composition of lamps and lanterns.

LED projection lamp consists of lamp housing, chip, aluminum substrate, constant current source, lamp housing with the same workmanship, different manufacturers make different materials, some have only appearance, thickness and quality cannot be guaranteed, poor use for one year, light attenuation is very large!

Chip, this is also the main gap, the same power with different chips, the effect is certainly different, commonly used is Corey, Puri, crystal source, but it is difficult to distinguish between true and false!

The price of different manufacturers of aluminum substrates is also different, and the price determines the quality!

Constant current source brand is different, the price is not the same, the quality is not the same, the constant current source of the impact of the stability of the lamp!

The last is the work, this need not elaborate.

So the choice of manufacturers is very important, why mass production is more expensive than small production.

Which is the greater loss if you covet cheap and lose your reputation?
