The LED (light emitting diode) is a semiconductor diode, also an electronic component, and was developed several decades ago. However, as a lamp, as we know and use, it is only a few years in the market and is constantly evolving.
Here are, briefly, the most important facts in simple term
Standard input voltage is 100~277V AC, but 347V or 480V high bay is welcome.
1-10V Dimming, Dali Control, Microwave motion sensor control and ZigBee control is available.
There is no set height. It depends on the geometry of the room and what lighting levels are needed. IES recommends approximately 30fc for most working areas.
The high bay is designed to run between -20℃ and 50℃.
The LM79 tests are performed at 25℃ +/-1℃ which is standard. The fixtures are rated for -20C to 50C (-4oF and 122oF).
Tempered glass or PC cover is standard. It ensures these LED are not damaged.
60degrees refers to the emitting angle of beams. You can put the light on a flat surface, turn it on then you can measure its angle easily. But it is inaccurate to observe with naked eyes. The smaller the angle is, the more condensed the light is. Generally, the angle of lamp is 30°,45°, 60°, 90° and 120°.
A good LED light with help of quality optics as directly as possible (calibrated beam angle) , to bring it where it is needed. So the product choice reveals itself through logic through consideration of the construction method and area of application.
Our led light includes different installation way, such as lifting by hook or rings, surface mounted by metal bracket. Any customized installation is welcome too.
