I’m a fan on the original M3, but the lack of built-in charging made it difficult to use as an everyday carry light. So for a while I was carrying the Jaxmnve M3 which is a clone of the OTR M3. That clone has some pretty annoying levels, though. I was glad to see that On The Road has release their new version called the M3 Pro that has built-in USB Type-C charging.
OTR says the new Pro model is 3mm longer, but you can hardly tell.
It’s got an xpl emitter compared to the xml2 of the original M3, on the right.
The new one has a black switch cover which seems to be installed from the back side instead of the front. This switch cover can be rotated if you push and spin. So I’m not completely sure how waterproof this is.
The original M3 clip had a shiny black finish, the little nub that catches on your clothes is a little bit tighter and the fit to the light was a bit tighter. The new clip is almost the same except for a matte black finish, a little bit more space under that nub and a more appropriate tension to attach to the light.
Here is my chart of amp draws on all five levels. This was taken using the UNI-T UT210E clamp meter. The M3 Pro is in the bottom right. You can see that most of the levels are the same as the original M3, in the top left, except for medium and high.
Parasitic drain was a super low 43 microamps.
Here are the lumen outputs from my TA Lumen Tube calibrated with a Maukka light. I tested all 3 at the same time using the same battery. They are all CW.
As you can see, the medium and high levels are a little bit higher on the new model. The Moonlight levels were too low to register so I’m assuming somewhere below one or two lumens. The turbo level is just a little bit less even though their amp draws were very close. I’m not sure why, but it’s probably not a big deal.
The charger pulled 0.94A at 5v. Just like the U16, the M3 Pro has a blue switch led that blinks when power is first applied. A red led turns of when charging (and for the low voltage warning) then turns blue when fully charged.
There’s still room for improvement in this light. I’d like to see them get rid of the high mode and add a level between Moonlight and Low. Going from 1 lumen to 120 lumens is a pretty big jump.
