FAQ2_Jiangsu Liangfeng Lighting Co.,Ltd

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

9 What about input voltage of led high bay?

Standard input voltage is 100~277V AC, but 347V or 480V high bay is welcome.

10 Are you going to have high bays that are controllable?

1-10V Dimming, Dali Control, Microwave motion sensor control and ZigBee control is available.

11 What is the maximum mounting height for the led High bays?

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.

12 What is the operating temperature range for the high bay?

The high bay is designed to run between -20℃ and 50℃.

13 What is ambient temperature of LED Fixtures?

The LM79 tests are performed at 25℃ +/-1℃ which is standard. The fixtures are rated for -20C to 50C (-4oF and 122oF).

14 Is the cover over the LEDs glass or plastic?

Tempered glass or PC cover is standard. It ensures these LED are not damaged.

15 What does it mean by 60 Degrees beam angle? How to measure it? And do you have lights with larger degrees?

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.

16 What about installation way and installation accessories?

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.
