Hey guys,
I’m wanting to build myself a decent midsized thrower. I’m after a host that’s not too expensive that’s somewhere between the head size of a convoy C8 and L2.
Size is a fairly important factor as I want something i can carry inside my hiking bag that won’t take up too much space.
It will need good heat dissipation as I’m intending to use a hard driven xpg2 or 3.
Unfortunately not many hosts in that size range that I know of. That supwildfire light has about the same head size as the L2 but is probably lighter weight.
The Utorch UT02 is probably more than you want to spend on a host, but it may be the size/shape you’re looking for. You can get it for about $40. Comes with XHP35 but doesn’t throw crazy far stock, about 90Kcd I think. But it would make a pretty cool light if you fully modded it, 300Kcd with dedomed XPG2: What did you mod today? - #3019 by giorgoskok
You should definitely check out the Brinyte B58u with xp-l hi. Built like a tank but little longer than C8 because of the ridiculously deep reflector. In a stock form it “destroys” similar c8 by a large margin.
With a discount code 18,6$ I think it is a real bargain.
Buy all this
-Flashlight
-BLF X6 driver
-Maxtoch 26mm XP MCPCB
-Dedomed XPG2 S4 2B
-A few centering rings for XP
You’ll need to file down the pill in order to allow the 26mcpcb to fit, also it’s good to cut a copper disc and put it under the mcpcb to fill all the space under it.
Mine does 240.000cd, if the XPG2 were from the old good ones it would be near 300.000cd
Hmmm some food for thought here.
The supwildfire looks like a nice cheap option but I’ve been stung with cheap before.
The UT02 looks good and seems to be available for ~£30 in the UK but seems a waste of a good torch and currently I’ve not modded anything with an e.switch yet so that’s a bit daunting.
The B58u sounds like a good shout, does anyone one here have one and a C8 to give me a size comparison photo.
Thanks for the advice so far.
That B58u does look pretty decent actually. It seems quite slim so will tuck nicely into my hiking bag. With a dedomed high CRI xpg3 in it should be pretty good. OT slightly but I am loving the new Cree LED’s, the 3000k high CRI emitters are perfect for me. They are all I use at the moment especially now I’ve learned how to successfully dedome them with no weird coronas!
Yeah…I don’t see that happening. There’s no way your driving a XP-E2 with a fet+1 dd driver. The XP-E2 Torch maxes out at around 3 amps vs other XP-E2s that max out at around 2.6 amps. That led will burn smooth up with that set up.

Sounds like I’ve been lucky and should swap out the emitter before the smoke comes out
I still don’t see the driver…you’re gonna have to make a believer out of me on this one. I’ve burnt up a few even trying to use 24awg wire and non-bypassed springs.
Uhhh, considering just how blue that looks, yeah, I’d say you’re overdriving it quite a bit, torturing the poor little critter and being unable to hear its silent scream…
Like I said, Es and E2s kinda max out under 2A if not DTPed and thoroughly cooled. I’m not interested in dumping 50% more current through it to get maybe 10% more light.
For me, 1.05A (3×7135) is the perfect sweet spot for an Al-star E2, maybe 1.40A for a bit more light. Can run them 24/7 that way w/o overstressing them, getting a decent amount of light, and not killing your runtime.
Plop it on a Cu DTP star, and you can raise the current a bit (maybe 2A…ish) and still get decent light w/o flattening out.
Someone (djozz?) had graphs of Es and Gs and 219s on Al cs Cu stars, and light output for various currents. Maybe goggle around and see if you can find it?

Oh, and don’t be cheap with the thermal compound. Get some AS5 and make sure there’s good thermal contact to wick away generated heat from the sensitive little critter.
