Review: Aleto / UltraOK 1x 26650 XM-L T6 Flashlight: An HD2010 challenger? (picture heavy)
On a whim, I ordered a 1×26650 XM-L T6 flashlight on ebay. At the time, I was looking for a single 26650 light. I had ordered an HD2010 already, and thought “why not have two?” So today, I received my second 26650 flashlight. I bought it as a mod host, and as you will see, I have some work to do…
Edit: Also known as UltraOK brand here on BLF.
It’s not a bad looking light with a good finish, decent ano, and a polished aluminum bezel. Heatsinking is decent and enough knurling on the body to add a visual feature but no grip enhancement.
There are o-rings at each joint, however most are inadequate, making the light splash-proof only.
Popping off the emitter star reveals the hollow pill and the driver on the other side. There is lots of room in there for driver upgrades. There is thermal compound on the star, however most of it is in the middle where it doesn’t help. redistributing this to the outer edge will help with thermal coupling to the head.
So, will this light stand up to the HD2010? Time for some beam shots!
We’ll start with indoor shots taken at 1m on a white-ish wall. (f6.3, 1/30, ISO100, 5200K) the dots are 16” apart horizontally, 12” vertically.
Aleto 26650 XM-L:
As you can see, the Aleto has a very tight hotspot, mainly due to the emitter being quite far (maybe too far) back in the reflector. It doesn’t show well in the shots but the HD2010 hotspot is quite a bit brighter. (When my light meter arrives, I’ll update with cd readings.)
The Aleto is not quite as smooth as the HD2010 either.
For outdoor shots, I was time limited due to -15C windy weather and I packed it in when I could no longer feel my hands.
I managed to get 200m shots only. In hindsight, I should have did 100m shots as well. (After I do my mods I’ll make sure and do a few ranges).
All three shots have the same settings: 22mm, f/4, 4s, ISO100, 5200K
First the control:
Aleto 26650 XM-L T6:
OK, it’s a clear win for the HD2010 (if the images show up OK for you; they look dim on one of my monitors). One big reason for this is the drive current; Aleto is putting out a meager 2.2A while the HD2010 is at 4.2A!
There’s obviously room for improvement here. The beam profile is nice, so increasing the emitter current should give some decent improvements. I’ll do an update once I’ve done some mods.
- Nice machining and finish, the light looks good.
- decent threads everywhere but on the tailcap, which are not bad once lubed.
- Comes with a 4xAAA holder and an 18650 adapter
- very nice thrower-style beam profile
- No visible PWM
- Tailstands as good as a HD2010
- Most batteries will not make good contact, if any. Magnets may be required.
- Rough threads on the tailcap
- Hollow pill which is integrated into top body section
- Next-mode memory (with five modes)
- Emitter is underdriven with resistive regulation (output drops with battery voltage)
- Emitter may be mounted too far back in the reflector
- 20mm driver
- 25mm star
- Slightly different ano on the tailcap
- Length: 165mm
- Head Diameter: 57.5mm
- Body diameter: 31.1mm
- Tailcap diameter: 33.5mm
- Reflector output diameter: 51.1mm
- Reflector inner diameter: 46.8mm
- Reflector depth: 31.7mm
- Lens diameter: 52.5mm
- Driver diameter: 20mm
- Emitter star diameter: 25mm
Weights (without battery or holders):
- Total: 222g
- Head: 110g
- Body with pill section: 78g
- Tailcap: 34g
Emitter: XM-L T6 1A bin
Emitter Star: 25mm aluminum MCPCB
Lens: uncoated glass
Reflector: aluminum SMO
Drive currents (4.2V): H=2.25A, M=1.50A, L=0.28A
Drive currents (4xAAA NiMH): H= 1.80A, M-1.22A, L=0.21A
PWM: High=none, Med and Low = audible ring only (similar to NANJG 105C)
As shipped, this light has issues. if you are looking for a mod host, there are several upgrades needed to get this light up to the task of being a good thrower. If you only plan on running 4XAAA NiMH, then you may be OK, since the holder works fine. Expect short run times on high and a gradual tapering of the output.
I plan to do some mods to this and will post the results when done.
Thanks for reading!
