After an almost perfect problem free build, things went bad for a bit.
Put a small scratch in the top of the heatsink, then overheated one of the pads on the stars re arranging wires. Was trying to hide wires, but impractical I think.
Pulled it all apart, added a 4C LED, then heard the letterbox, new LED order arrived.
Did not manage to get the top copper plate back to shiny mirror finish, but decided a brushed look would be cool, cleaned up pretty good, stopped at 800 grit wet n dry, did not bother with 1200.
Added one of the T6 3C LEDs from the new order, so now 3 x T6 3C LEDs. EDIT -wrong! config is 2 x T6 3C, 1 x T6 4C
Since build almost complete and looking good, pulled reflector from my V1 Triple FM3
and assembled. Used lots of lube around lens so I could tighten bezel without spinning glass on reflectors and scratching lens.
Used some Arctic Silver around the heatsink and assembled head.
Grabbed a 4D tube and old tail with low resistance modded spring and stainless external ring for strap / lanyard.
Tried something different with mag switch rear spring, soldered 22 AWG wire to connector , through spring. Then metal epoxied around the spring. The spring now has no use, was just there to locate wire while epoxy set.
I had been connecting to power supply at various stages so new it was a worker.
Fired up with 4 fresh Smasung ICR2000 18650s and measured 3.8 Amps at tail.
Pleased to see a large amount of light coming out. Hotspot is a bit tighter (now very tight) indicating my V1 had 1 reflector not quite level (confirmed with visual inspection)
Took out for a photo, went to grab camera and heard a bang. Light rolled off sun bench onto the ground.
2nd stuff up (LED overheat, # 1)
Pleased to see only a tiny speck of ano missing from 3 inch head, tube untouched, extra scratch in tail, it was already scratched.
Over the drop instantly - it's a user now.
V1 will be rebuilt into Elephant for shelf queen.
1st time I've ever had a light roll of this bench:
See small white speck - only damage I could see.
Bezel has around 1 mm extra to tighten, will wait until I get a pot and install for dimming, tightening the bezel down without spinning lens on reflectors and or ripping domes of the LEDs is the only part of this build I get a little nervous about.
It should be dark in about 30 minutes...
I think for this light, car headlight may be good comparison
Just realized checking above, I have 2 x T6 4C, 1 x T6 3C. That was my original plan, found my way back there by mistake...
I did want just a tad cooler than 4C.
