99% complete.
1 reflector not straight, having a rest after huge build and sort that out later.
Huge build as I needed a huge heatsink for FM 3 inch head.
Drill press, hacksaw etc and quite a few hours and 1 Copper/ Al heatsink!
Not that it looks small there, here it is next to H22A P7 Mag D / Download Multi Sink
1 LED epoxied. Other 2 being done together, perspex so I can see before applying mass.
Cree XML2. 2 x T6 3C and 1 x T6 3A on Noctigon 20mm copper stars.
Cree XML-10R reflectors.
Trial fit in head. Yes, lens is there. Reflectors are around 1mm shy of the lens and rattle around but don't fall off.
I need spacer/spacers. PC case rubber spacer/standoff almost works.
There is still a 3mm screw for handling.
Complete with 3D backend.
Yellow piece is the standoff. 1 reflector slightly wonky. Centered, just not pointing straight ahead.
Going to be patient and think about good solution. Maybe just epoxy tiny piece underneath reflector to shim up a bit..
Beam has 2 LEDs burning 1 hot spot with 1 LED making an oval shape addition on 1 side.
Nice to sort now, but honestly exhausted after that sink.
Direct drive at the moment.
Hooked up power supply, through the mag switch 9.5V resulted in 2A, 10.05V required for 3A.
So that's pretty low VF, DD will need caution.
Results with Samsung ICR2000 / Sony Konion (2 years old) cells:
3 x ICR2000 @ 3.81V = 4A
3 x Sony konion-V 3.85V = 3.7A
3 x Sony konion-V @ 3.95V = 4.4A
So the Sonys fully charged will be around 5A. Samsungs just too gutsy to use DD.
I'm thinking Der Wichtel 5A buck driver and use 4 x 3400mAh LIONs in Elephant or 4 x 26500 in the 3D Mag.
Regarding spacers for reflectors/LENS, anyone have suggestions?
I've thought of trying to glue 3 flat orings to top of reflectors.
For this assembly I managed to push down hard on the lens while screwing bezel down and kept lens still, rotating inside well lubed bezel
so if I had some orings that were a bit stiffer than normal it might be possibe not to distort the orings and twist them off the reflectors...
