I did’n t measured before and after but it feels to get hotter faster with hand.
If somebody will do this also please measure temperature with time on the side fins before and after the thermal paste.
The light will never be any good because of the messed up user interface, but the extremely out of focus optic certainly challenges the UI in things done wrong in this light, I have rarely seen an uglier beam profile.
The focus problem is because the optic rests on two small opposite ridges on the inside of the head that are too high up. Because removing plastic is easier than removing aluminium, I filed a bit off the optic on both sides to make it sit deeper, closer to the leds. I broke off one of the legs of the optic in the process, but in the end the light closed up fine.
Because the optic now falls inside the head, to make the glass lens still clamp the optic in position, I added a paperclip ring on top of the optic (a silicon o-ring did not work, it twisted out of position when closing the bezel)
The paperclip does not spoil the looks of the flashlight.
thanks this was my first TIR light and I thought the Beam is OK
I did glue the paperclip only on 2 sides where the optics is filed down because otherwise it blocked light from the TIR
after I modded the TIR I could see it does throw better and beam looks better overall
if you need a driver how about a TA one I can make you one with Narsil just for material costs, the light is great with Narsil
Yes, that is thw other way around to get leds and optic closer together, someone posted already that he had done that succesfully. I will look that post up.
About a new driver: I’m not sure that can be done while saving the internal charging function? I don’t think that could accept to have a flashlight with a charging hole that is there doing nothing (and fancy aftermarket cover for that emty hole :party: )
(back in the days when I wanted a flashlight for actually using it, a random hole in it would be perfectly acceptable, but that was a looooong time ago, I aim for at least perfection now, and of course never get there)
I can partly see what you did there, that looks like a fantastic modding job! (did I mention that I’m lazy? :party: )
Edit: I just read Toykeepers review of the D4, and my lazy me (plus unavailability of the many hours it will take to do the mod) will just wait for Hank to sell them, it has everything the S42 should have had without difficult modding :innocent:
i filed about .8mm and it has improved the beem a lot! Optics seem to fit ok without adding anything. Glass tightens up against it fine and works good. Thank you again for the tip.
