As the high cost to install,repair or replace a high bay light,the quality of the LED high bay become very very important.
How to choose a LED high bay or test the sample?
1. Meet the light requirement
No matter what the quality is,first the LED high bay should meet the lux desire,if the light produced by the LED high bay is not bright enough,the choose will be a wrong choice.
The lux on the room will be determined by following perameters:
A . Install hight of the LED high bay
B. The angle of the LED high bay
C. The quantity of the high bay installed
D. The lumens of each high bay
2. The right materials
The right materials is not the best materials,even a LED high bay is made up by the best materials,like meanwell driver,Cree LEDs,best heatsink,the product may also fail in the future,the right materials is to meet different desire,like some customer only need 2 years warranty,some may need work at 60 celsius…
Cost-effective materials while the cooling is guaranteed,this would be a good product.
Cooling is the most important to the LED high bay,while we use a good driver,even good LED chips,but the heatsink and cooling technology couldn’t gurrantee the LEDs work at lower temperature,the LED high bay will fail definitely.
So what temperature could gurrantee the life of the LED?
For the SMD LED products,the pads of the LED should below the temperature of 80 celsius,and for the COB LED,the pads of the LED should be below 70 degrees,however,the lower the temperature,the longer life of LED.
4. Good LED driver
A good LED driver is not same as brand LED driver,like meanwell,beside the meanwell driver there are also some other Chinese brand drivers that have great quality and competitive price.
Not damage is not the only factor to judge a good LED driver,THD,effiency,PF,output accuracy is also very important,if these factors are not good,they may harm the LEDs,and reduce the life of the LED.
