Many clients consider the power only when choosing the led high bay light, and ignore the most important point that why we buy the led high bay light, It is the brightness.Including some large projects, the lamps designed data used by the designing institute are many years ago,but with the update of technology, the parameters have changed greately. So how can we choose the led high bay light with good quality, high briness and energy saving?

First of all, we have to look at the overall light efficiency of the lamp, not the led chips light efficiency, In the past  the parameters used by the design institute were basically 70-100lm/w , Now the mainstream brands on the market are 100lm/w, and all most of  Royal lighting , the light efficiency 150lm/w-200lm/w.

so we have to take it into consideration when choosing lamp power. In the past, one 200w  led high bay light, may be enough with Rongya Lighting's 100w led high bay light. Let's do a calculation. If the number is 200, how much electricity can we save in a year? For example, the electricity fee is one RMB for 12 hours a day, 360 days a year. That is 172,800 RMB.Another point is that some low-end products have high power and low light efficiency, so they can only use high power to increase brightness. However, due to heat dissipation problems, if the high power is used for a long time, the life of the lamp will be much shorter and the light decay will be much greater. Therefore, some merchants have a plan to reduce the power. At the beginning, the power will be reduced to 50% of the original power after a few minutes. Then the brightness will naturally not be achieved.
