Since that LED has been thought as the highest efficacy lighting technology by the world, LED lighting fixtures develop rapidly without stop, which also drive manufactories and dealers devote themselves into LED lighting.
The technology of LED industry is not skillful and there’s no universal standard, besides, different manufactories don’t use the same materials and the production technology also has a wide gap among them. As a result, the quality of LED fixtures differs in thousands of ways. Just because of this, the price of LED fixtures is volatile in the market. Even though the appearance, structure and function are similar, the price is totally different. Most of customers can’t identify the quality and where is the difference among them. Now, let’s learn some methods of identifying the quality of led high bay .
1.Luminance: different luminance is different price and they are not always in direct proportion.
2.Anti-static capacity: the stronger the anti-static capacity of LED high bay, the longer the lifetime. Generally speaking, its anti-static capacity is always bigger than 700V.
3.Beam angel: different use is different beam angel. Special beam angel is much higher in price, such as diffused angel.
4.Wave length: if wave length and color of LED high bay are the same, the price is high. It’s not easy for manufactories without LED sorting machine to produce pure color fixtures.
5.LED chip: the luminophor of LED is chip. The price differs greatly on chips. Import chip is much more expensive than domestic.
6.Chip size: it is expressed by the length of side. The quality of large chip is better than small chip. Price is directly proportional to chip size.
7.Power: according to manufactories’ design requirement, it is divided into constant current power and regulated voltage power. Both powers are often critical to the lifetime of LED. If a fixture doesn’t work, power is most likely burnt out.
Expert suggests purchasing LED fixtures from famous manufactories to quality guaranteed.
