Horticutral Lighting
You may hear of some Chinese supplier declare that their LED high bay UGR (Unified Glare Rating) value <22, and when you buy sample and test, you will find out their UGR value is actually higher than what they declare. Why?
Actually we have help some of our clients test some sample, we find out that these suppliers all imput a higher lighting surface area value than the actual lighting surface area value while making IES file, in this case, the UGR value <22 can be fabricated.
And there once some clients who used to choose milky cover to avoid higher UGR value, because they think LED high bay with milky cover, it looks comfortable to eyes, while when project finished installation, they find out that the lighting effect is not as goods as they think. Why?
Actually the above two questions all refer toward UGR, if you do not know what is the main factor affect UGR value, you will never know what is the right solution to reduce UGR.
There is one formula of UGR, and it looks complicated.
To put it simply, total lumen, lighting beam angle, and lighting surface area are three main factor affect UGR. It is concluded:
Higher lumen with higher UGR,
Smaller lighting beam angle with lower UGR,
Bigger lighting surface area with lower UGR.
AGC always focus on offering a better lighting effect to our clients.
Now we already have UGR<18 solution-HiCloud high bay+50 degree PC lens H25203+PC reflector H00C01A(as the below picture show)
As you can see from the above IES file, the solution works effective, with UGR<18, the efficiency is still high up to 138.72 lm/W.
Request IK10 to be used in sports field? Just remove the PC reflector, you will still get UGR<22.
