Grabbed my magnifying glass to check Sister G-13 and M in the closet tent. The glass focused the LED on my arm and I could see all but the four UV bulbs. The four didn't show up on my arm because I am quite white. So, I grabbed my keyboard, which is shinyish black, and was able to see the UV's, along with all the others. If I had something flat black, they would show up better. They're hard to spot, but able to be spotted. All my lights are working. What loss in efficacy, I don't know.
I got to trying the same thing with other lights and got the same result: A perfect image of the light source! Took a look at my HLG and could see all the little life givers.
