Yeah heat will be a huge issue. I had an 11D (6D + extensions) 2/3Ds with a 64458. The head was too hot to touch after ~10 minutes. I had ceramic insulation too.
The 64623 is a beast at 15.6V. Sets fires easily. on 5-6 32650s it will run a looong time in full regulation. Use a regulator instead of just a softstart.
Yeah, I don't think I'll be running it continuously for 10 minutes.
I already have a regulated 64458 light in an Elephant II body with a 3 inch reflector (using an Alan B programmable regulator), I'm really looking at how best to use one of my AW soft start drivers.
