No Clue on runtime but I would guess around 2 hours on high.

Re: 15 Watt Ostar LED Custom
Thanks TB I was trying to copy one of your patterns  The Diameter is a little bigger so it looks different though.

Re: 15 Watt Ostar LED Custom
I would love to see a beamshot comparison for this lil' guy compared to... well, anything else - maybe a normal 3D Maglite... 
Nice work... as usual!

Re: 15 Watt Ostar LED Custom
Alright, you got around to building a light with the 6 die 15watt!  Have you checked the forward voltage on yours? My 15watt is way under the average vf stated by Osram. They claim at 350ma it averages 19.5V and at 700ma it averages 22V. Running on 6 x R123 the bFlex wouldn`t function properly at 750ma if the vf on your Ostar was as high as the stated average. Good, more efficient! But I think you guessed a little too long with the 2 hour runtime at 750ma. Does the beam pattern seem any different than the 4 die 10watt Ostar? I`ve powered my 15 watt up but I haven`t put a reflector to it yet.
I like the battery tube design!

My VF at 700ma is 19v. You are correct on the runtime it's more like just over an hour on High. It pulls 650mah from the battery's on high. The beam is the same.

Hello Mac,
are you going to rebuild some of this flashlights again  ?
Maybe a silver one like in your gallery?

Re: 15 Watt Ostar LED Custom
I'm running one in a Mag drop-in from Wayne at Elektro-Lumens. The reflector is a 34.5mm Fraen designed for the emitter. I have it in a stock 5C with 5x AW C cells and a deep tailcap:
I took it out last night, and it's pretty much like the SF-V. Wicked throw/flood. I need to take it to the shoreline, because there's no place in my neighborhood with enough room to really do a beam shot.

Re: 15 Watt Ostar LED Custom
Hi, great work! Where did you get the reflector from? I can't find an online reseller for fraen  .
Thanks in advance.
