Bought this SR90 reflector a couple years back and wanted to build my ultimate thrower. The reflector housing, copper heatsink were machined on my lathe & mill. The lens is from flashlightlens.com and is UCLp. The driver is the mighty HX –1175B1 pushing a dedomed XP-L V6 1D at about 6A at the tailcap at about 4.8V. Power is supplied by 4 Tenergy 10,000mah NiMH batteries. Maxtoch BLF-TE for size reference. Don’t know the kcd but it handily spanks the Maxtoch BLF-TE and my modded Yezl Y3 with UCLp, resistor and dedomed XM-L2 U4 1C.
Well the TK70 was the only “4D Monster” flashlight I could remember that was close in size. If I am able will post some beam shots this weekend. Is the prefered method done with the flashlight on a tripod?
I don’t think you need a tripod, it just helps you get a good picture. Anything you can use to steady the light while you get the camera focused will help.
Really a compliment, I’ve seen your posts over the last four years and the amount of work that goes into a truly hand built, machined works of art. Having been a machinist for 40+ years, I know the walk is more than having machines, it’s the skill of the man on the handles that creates the finished product.
I want to upgrade to XHP35 HI and go to 4 32650 or 26650 cells. What would be the recommendation from a driver these days. Am tried of screwing with the NiMh cell and my current driver. Although it was a screaming thrower four years ago I believe there has been improvement in technology and feel my basic reflector is a great design. To recap recommend driver for XHP35 HI N4 with 4 cells inline.
Thanks,
Willie
