Incredible! Looks so simple to the naked eye, but its a very well thought out contrapment for those that know what really went on into creating this lumen tester.
How sturdy is it? If the area around the horse shoe was longer, if would be a very stable base, but I suppose you wanted it as small as possible, and if its sturdy enough this small, then even better.
I guess your not really pushing down on the pvc, so it shouldnt tilt forward.
So how big is the opening? Can the head to my btu shocker fit? my biggest headed lights are my trustfire j20, shocker, and the tn42.
I’m not quite sure in understanding the black electrical tape….so is the tape still left inside the pvc?
And lastly, so how does the readings work, just put the hs1010a on auto and whatever number you see, is the lumens? So in your photo, it shows 123, does that mean 123 lumens?
