You could try adding a couple pieces of paper under the black centering thing. See if that makes it better or worse. (this moves the reflector away from the emitter)
If better, add a couple more pieces of paper.
If worse, then you might have to sand down the bottom of the black piece to make it a tiny bit thinner. (this moves the reflector closer to the emitter)
Its less in reall life i guess, the photo makes one spot brighter.
What i also tried is put them on moon light mode and walk towards the wall i will see a square(the led) with mine GT, the other GT there is never really a square it always kinda stays a cirlcle. Maybe other people can try this and tell what they see(or picture)
It’s btw in no way any criticism. Both light throw extremly well. Just slight difference in beam profile, but with so much variables its expected that there are some.
I’m going to measure throw of my GT and Nicolaas’ GT somewhere next week, it seems that you and/or your dad are also in or near Amsterdam?, we could make it a 4x GT session then if you are interested.
I would be very intrerested to find out what exactly is causing the difference - and how big the difference is on Djozz’ light meter…….
Provided good whether we could go outside (we have a nice beamshot area at a 5 min drive) and compare our GT’s to some other lights,
like my TN42 and modded Nitecore TM36 Light (dedomed XP G2 S2 with 849Kcd).
I think it’s the reflector. There’s a difference in reflection, my son has almost mirror finish (like it should be), while mine produces a blurry image of everything that reflects.
