Amutorch XT45 Quick Review [Gen 1]

Hello BLF! I have been lurking on this forum for around a year now, and I thought it was time to make a contribution myself, as I haven’t seen many reviews of this light yet. If you have any questions feel free to ask them!

Quick Review
Just got my hands on the Amutorch XT45, the cheapest SBT90.2 light on the market (I paid 61€!).

Build quality: Build quality is very good, with no imperfections, and the switch is stiff but not excessively. It’s surprisingly pocketable (if you have big pockets), weighs slightly more than an E07 and it’s slightly longer, see the album for comparisons.

Led and runtimes: The SBT90.2 is incredibly powerful, so the body gets too hot to hold after just 1 minute and the light steps down to low in just over 5 minutes, before climbing back up to an estimated 300/400 lumens and sustaining it. Here is the turbo runtime graph (battery is samsung 40T):

At around 3.0V, the light stays on only in low mode, with 5 seconds bursts on medium and high.

The modes are an estimate based on my ceiling bounce app:

LOW – around 50 lumens

MEDIUM – 800-850 lumens

HIGH – 1300-1400 lumens

TURBO – 4500 lumens

The medium mode is not sustainable, at 25°C room temp it heats up to the thermal limit (60°C?) in just 5-6 mins, then falls to around 300 lumens but tries to get back up to 800 as soon as it’s cool enough.

Tint/throw: The colour temperature is around 5500K and the tint is greenish, I improved it with a minus green filter and now it’s much better. Throw is slightly less than my Acebeam k65, which is really impressive, and I really like the beam profile. Here is a beamshot compared to my FW1A xpl-hi 5000k, the tint is similar with the minus green filter on (FW1A on the left, XT45 on the right)

Conclusions: For the price, I definitely recommend it! The only things I don’t really like are: the medium mode which is too high, and the fact that it’s not waterproof at all as the switch let in some water during this water cooling test on turbo:

Many thanks.
Does it have a forward or reverse clicky?

Thanks for the excellent review. The output curves are very helpful! Seems like the temperature regulation is not very refined compared to Olight and other premium brands. Too bad the tint is green.

Not sure if it’s the same version I got. But what I have on hand has this UI:

reverse-clicky tailswitch
full-press = turn On/Off (has mode memory)
half-press: High -> Medium -> Low -> Very Low
double half-press: Turbo (Turbo is not in regular cycle, and is not memorized)
triple half-press: Strobe

Just ordered the upgraded version from Amutorch today. I was going back and forth between the X9L, NI40 and chose the XT45 because it just looks very appealing to me and got a great deal through Amutorch with the coupon they gave me, thank you Amutorch :D. I’ll get the other two later on. I just wish they used a step down/up thero regulator instead of the 30 sec timer.

So basically a light that can’t sustain medium (~800 lm) but drops to a mere 500. Facepalm

I have this light (2nd vers). It does sustain the medium mode well, head never got too hot.

Yeah, unfortunately on the first version it gets too hot to sustain unless you are using it in cold temperatures.

Got the 2nd version. Measured around 150Kcd at 2second switch on.
Test was done at 10 meter throw.
