2, The another way we need to know the factory’s certification and know the factory’s market. If a factory major for low end market, even the price is cheap. How you expect they can make a Europe or USA standard quality product for you. But how to know it ? Very easy, low end market factory usually very small, usually don’t have ISO, SGS, or TUV factory inspection. You can know the factory details from these factory reports including how many skilled workers, QC stuff,engineer..etc.
Secondly; Evaluate is product quality.
1,First look the high bay light configuration, configuration affects the quality of the product, generally check the led chip and the power supply, the Good light source match high quality power supply can let the LED highbay work stable operation for a long time.
2,Check the power wattage, On the market, Always have some company sell a 80W high bay light as 100W or even 150W , for new buyers cant recognize, but through the electric meter connection, can see its real power. The virtual standard power directly cause to insufficient illumination, so it will actually affect the work of the factory workers below.
3, Look the material and type of the lamp radiator, in general, the higher the purity of aluminum, the larger the heat sink, the better the heat dissipation effect. The lamps with bad heat dissipation will make a lamp with high temperatures in a few hours, and the heat that can’t be released can continue to affect other led high bay light accessories, such as light source and driver.
