OMG :person_facepalming:
I read some posts where people dedome a led, and I have never read that flashlight was hotter after that so I found it strange when you say that, but obviously I did not understand well.
It is not important to me if colour temperature changes, only thing that I want to know is a beam of the light narrowed and can it gain more throw ?
With U4 when full zoom there is nothing but clear hotspot ( square ), and with HI V3 there is a ring around hotspot ( square ). Is this also a case when you dedome a U4 do you remember ?
Why are you crying? If you are white wall hunter just buy reflector light and enjoy on a nice wall beam pattern.
Aspheric beam mostly has those ringy imperfections around die. They can be eliminated… If you want pure square beam than use black oven paint or similar and apply lightly and precise.
I even enhance reflection around sqare (flood) in my builds and while it ain’t look nice on a wall I really don’t care for that. I really care how it throws at nigth an if I can get usable flood out of it.
There are even reflector - aspheric flashlight combinations out there with even more ringy beam like this:
I cry because that pic is result of ‘’dedoming’’ a led, if it can be called dedome, because I screwed up.
Original led was clear and without anything just pure little square, also a fabric V3 HI is clean and pure, and then look at my result
There is visible some marks like + and dot also too many residues from the dome, it look pretty ugly. When I watched on YT about dedoming it was easy and fast, but in my case not at all.
Those are just common reflections. The dome blocks those reflections. After dodo mint it is normal. Your dedome doesn’t look bad at all shining on the wall.
Yes, you assumed correctly.
It doesn’t affect the focussing zoomed in, the head stops at the LED shelf of the pill, it moves past the copper ring (1.8mm diameter wire).
Planning on adding a bit more, because i like it when you can zoom out as far as possible and have a wide flood.
Speaking of zoomed in and focussing, i replaced the 1mm thick copper DTP MCPCB with a 1.6 mm thick one (Noctigon) so that it does no longer “over-zoom” but stops at focal distance of the lens.
So in all zoomed out has the lens now 1.8 + 0.6 = 2.4 mm closer to the LED than how i bought it.
(changed the switch too, it’s a reverse clicky now, and recessed the boot a bit so it can tailstand better)
