A while ago I asked for help with shipping and DavidEF was kind enough to lend a hand. I appreciated it so I offered my services in return. Shortly after doing so the ebay seller I was trying to buy from contacted me and said they could ship direct to me. I didn’t want to renege on my deal with DavidEF and what he wanted kind of lined up with something I wanted to do anyway but hadn’t got around to it yet. So we agreed on a little bird price (cheap cheap).
From memory the goal was “an srk that can sustain 6k lumens from 4* sst-40 (or direct drive without thermal kick-in until the batteries run down)”. Now I have my reservations as to whether this is possible. I looked up other lights that sustain that kind of power and they are pretty much all actively cooled lights. Be that as it may I won’t let it stand in the way of this build :smiling_imp:
I don’t have an srk but I do have a Trustfire df009 which has a nice 4* 18650 body. The battery setup is 2s2p but for some reason I had it in my head that it was 4s. DavidEF will supply the electrical gizzards and I have a reflector on hand that’s suitable but doesn’t fit the df009 head so I need to conjure up some kind of custom head.
Side note - just recently Dale mentioned his 458 Ham’r which I had to revisit. Kind of similar idea - srk style with custom head.
I drew on the power of the gods to rise above the chicken scratches that I normally do
Start with one big lump of aluminium and hope and pray it doesn’t slip in the chuck :confounded:
To make sure the head was bored to the correct depth to suit the reflector I had to make up some centering rings and do a test fit. These were a bit of a pita so I only made 2 of them to get me past this point. Later I try to make them again… and again…. you’ll see
Phase 1 complete. More to come tomorrow
