Regular spectrum ratioblue460nm:white14000k:red630nm:violet420nm:UV380nm=24:25:2:2:2
They said they can customize the ratio of lights. but standard is listed above. they are quoting 125 per unit with optics and recommended two of these units
I have looked at buildmyled lights but it would cost me $520 ( recommended 2 48") which is double than what the above ones cost.
Does any one have these units? is it worth the risk for the cost? its a lot of features for almost half the cost
can you recommend any changes to the LED combinations than the default listed above
