[Review] Amutorch X9

Some specs/mod info for my X9:

  • amps: 15 on a LK at 4.20V
  • lumens: 5440-4830 (Tom E #'s), 4800-4260 (ANSI)
  • throw: 40.5 kcd (402 meters) taken at 5 meters
  • driver diam: 29.0 mm, pure FET based, std FET gate resistors
  • pill has only 5.0 mm of clearance above the driver - tight for piggybacking
  • MCPCB is 1.5 mm thick
  • shelf is 2.0 mm thick
  • LED wires are 20 AWG, longer than need be to allow driver to be pulled out
  • driver was glued with silicone like substance (plyable) - knocked out using a solder pick tool thru the LED wire hole -- came out easy
  • springs appear to be IOS BeCu - high quality
  • the switch appears to have a piece partially broken off - doesn't appear to effect it's operation, but may replace it - don't think I broke it, not sure
  • that "2R2" component is used in the USB-C charging circuit, not for LED output

More pics from a break down:

Thank you TomE for those infos !

any idea how to make this nice flashlight more bright? which leds should fit without driver change? /dont want to loose usb port/…

Well, I modded my X9 to XHP50.2's, gets ~10K lumens, but I piggybacked in a driver. Looks like the stock driver is FET based, so you could just swap the LED's to XHP50.2's, assuming/hoping it can take higher amps, stock is ~15 amps, XHP50.2's in my custom driver setup hits 30 amps at max.

I don't see any other option for LED's to get more output, and the good thing is the stock driver is already FET based. But again, you always throw the dice when bumping up amps. I'm guessing it should work ok, because 15 amps is already a big #.

this sounds very good….:slight_smile: you wrote to me…is there any pizza xhp50 neutral source? i guess you got them separatly…

Dunno - KD has them in 6500K and 6000K, both CW, same with MtnE. Should be 5000K or lower to be NW. I haven't checked Mouser or Arrow in a long time.

What battery are you using? I wonder if my old blue Littokala cells will even hit 30amps.

LK's won't, GOLISI 26650 though did for me.

any idea where is this flashlight available please? with typical usb ,not magnetic…

Well the old model had USB charging, new model is magnetic. I got one of each but both had the charging removed because of piggybacking in a replacement driver.

Neal lists the old model here: https://www.nealsgadgets.com/collections/amutorch/products/amutorch-x9

but I'd check with him first if it's really USB charging.

BG lists the USB charging model here: https://www.banggood.com/Titanium-Black-AMUTORCH-X9-SST40-XP-L-HD-3600lm-High-Lumen-Flashlight-USB-Rechargeable-26650-Flashlight-Portable-4-Modes-USB-Charging-Work-Lamp-Camping-Hunting-Emergency-Lantern-p-1463001.html?ID=2246143494&cur_warehouse=CN

BG I'd trust less to ship a USB charging version.

One month back order… As many other models…and from neal never again rather…

Do you want my red X9 with xml2 nw?

Where you from? Hm… I wanted reflow it with xhp. Not sure if is there space for it…

Poland.
What xhp? 50.2? X3 has already done it

yes yes……xhp 50…but neutral white.sure not cool white.and i cant found them sadly…as a tripple.but for this you need bigger reflectors …so maybe the xml version can fit… cos there are bigger reflectors than xpl version…:slight_smile:

I already did it too. I got a triple XHP50.2 3v and now have a triple XPL HI V4 3C. The XHP50 triple was done before I got into Anduril, so it's NarsilM v1.3, while the XPL HI just finished the other night so it's got my latest Anduril.

I piggybacked in a 20 mm 0.8 mm thick FET+1 driver by DEL, OSHPark for both of them, wiring up the blue and read switch LED's so comes out look'n purple-ish. Not that I like Amutorch's:

yes we know we know…but its sold out or what….and you inspired me to make it xhp triple…with stock driver to save usb port.i dont want flashlight without usb anymore…

Tom E is there enough space inside to add a driver and keep components from the original pcb so as not to lose charging?

Not really sure - it's tight, but no where near as tight as the AX4, but fortunately with the AX4, I had a driver with a mounted switch that fit, with some tweaking. The X9 has the LED resistors on the driver. I left the resistors in place and wired them up to I/O pins #3 and #7 separately to the red and blue. Right now Anduril supports an AUX1 and AUX2 LED, but unfortunately doesn't take advantage of using them separately.

I've found for batteries, it's a tight fit as well. The problem could be my spring bypasses though - might have reduced spring height just enough to cause problems. Flat top LK style batts fit good, but the ones with a protruding top are a tight squeeze. I marked up the batt- end of a new EFEST 4200 pretty good.

Btw, those type of switches are prone to failure - they get bend back over time, sometimes just making it harder to activate, other times can break the contact, or bent back far enough to not work. Can't tell from the pic, but I have a clear epoxy backing that switch to support it better -- highly recommended even for the stock driver/setup.

from where you got the tripple xhp board please? iam looking for neutral white colour….
