Review: UltraFire T90 SST-90 3x26650 Flashlight from Wallbuys (Picture Heavy)

This is a clone of the X6 with 26650 support then?

Is it better than the x6 output wise?

It is there, body diameter.

From what I read on here and DX, the TF X6 driver pushes about five emitter amps, so this would drive 40% harder. I think the output is slifhtly better, but the X6 reflector might be better, I haven’t seen it though…
I think this driver is better for modding (details coming soon) and 26650 support is a big plus. The larger body tube pairs up better with the huge head.

Nice review relic! How does the throw compare to the HD2010? Any beamshots?

sounds like you’re thinking of a resistor mod AND mt-g2

if it lives, I’m guessing 2x overall output, same throw

:open_mouth:

Was dragging my posts because of the thousand post giveaway… Excellent light, excellent review… I am curious as to the variations in performance between the two. The ones that use 18650 & 26550… Any ideas?

It outthrows the HD2010 stock, and with the mod really outthrows it. No outdoor shots yet, it’s been snowing just enough to make it not possible.

I think the die size of the SST-90 and the MT-G2 are similar, so I’m expecting (hoping) the hotspot stays the same size, therefore, more throw… we’ll see :wink:

I can’t compare, but based on reading here and there, the T90 might perform slightly better (higher emitter drive current, more capable driver). I’d like to compare the reflectors, since that is where the most important difference w.r.t throw will be. Looking at the reflector sold on DX I think they are identical (and it is reported that this is the one in the X6). The dimensions match my measurements.

Thanks relic38 for the review. That thing is a real whopper. Any chance of a shot in your hand (hands)?

Here’s a not so great in-hand shot.

holy crap - that thing is 14” long!

resistor mod? Are you going to push 9A? :slight_smile:

Check the first reply for my resistor mod.

And, yes, I am pushing 9 Amps. You could push a lot more if you wanted to. :wink:

Thermal test just finished, results added to mod entry. She runs a little hot, but with some airflow, it should be OK. This was with it just sitting on a desk.

Wow. Your hand shot shows just how big that monster is. Well done on the driver mod. You really know your way around these things. A GPS would not even show me around on electrical thingys.

wow… bravo!

I updated the throw number, my lux meter is rated to 50klux, but will happily go above that and lie to me. I tested at 5 feet and 12 feet and calculated the candelas; ~73kcd after the mode. Based on the skew the meter was giving me, the stock candelas was probably 57kcd.
Not too bad. I hope it doesn’t snow tonight :wink:

very cool! ive always liked the sst90

Awesome review relic. Thank you

You should really dedome it...

I’ve thought about it, and I might eventually. I really like the beam the way it is with this amount of spill. Looking at those shots, most of the spill disappears, becoming a pure thrower. I’m not sure yet if that’s what I want from this light.

Great review with modding instructions! Thanks.
