bvanant 179 Posted December 16, 2021 The amount of light cut out by a filter is independent of the source light over the wavelength of the filters of course). Most folks are using the same COB leds with the same color spectrum so unless you went to great lengths to engineer a specific spectrum the transmission should be fixed.

vaidhy 4 Posted December 16, 2021 Thanks.. I did not think about it this way. Then in fact, a cheaper LED with more blueish spectrum would do better than an more expensive LED with a more warmer color with the downside being that at night time, you are screwed.
