Top 3 tips for choosing LED High Bay Light
2017-04-05 15:56:19

LED high bay light cut your spending on electricity bills by 70% or more. 3 tips to know when choosing a LED high bay light for your warehouse or factory lighting.

1.       Choosing high lumen, Not high wattage

Brightness, measured in lumens, not wattage. When you are shopping for LED high bay light, compare lumens to be sure you’re getting the amount of light, or level of brightness you want. Same color rendering index Ra80, higher lumen output is better.

For example, to replace a 400W metal halide lamp, look for a low power LED light that gives you above 18,500lumens.

2.       Light distribution and Uniformity.

The right product with same lumen do not mean provide same illumination. Different optical provide different light distribution, so choose a product that is designed to ensure precise optical control of the light distribution. Put simply, beam angle.

LED high bay light with a narrow beam angle suitable for a higher ceiling or narrow aisles, wide bean angle are better for a open area. Recommend to installation height less than 10 meters.

3.       Consider your working voltage and Frequency

The voltage and frequency of alternating current (AC) electricity used in varies from country to country throughout the world. Most countries use 50Hz (50 Hertz or 50 cycles per second) as their AC frequency. Only a handful use 60Hz.  Before your purchase a LED high bay light, checking your existing working voltage and frequency. Universal voltage 85-277V AC for flexible use worldwide, but three-phase electric power are widely used in industrial facilities, the working voltage consider to 347V to 480V AC.
