I really like my On The Road M3 - I like it just as much as my Olight S Mini. The M3 is a fantastically made, easy to pull apart, and really practical bit of gear. It's obvious they've taken a few design queues from Olight across their line up...
Which makes me wonder...who's waiting for On The Road to come out with a headlamp - perhaps a competitor to the Olight H2R Nova? Their marketing department doesn't take requests do they? :)
OTR would have some stiff competition from the already established Skilhunt H03 series headlamps. I don’t know about how well that bicycle lamp turned into a head lamp would work out.
Honestly, there isn’t a huge weight penalty going from an 18350 up to an 18650 at 45-50gm, unless you’re an ultra-light backpacker. An 18650 has easily 3 times the capacity and better current handling, if you’re sporting a ‘blazer’ HL.
My 3 HLs are a Black Diamond Storm (3xAAA), a Fenix HL30 (2xAA) and a NiteCore HC50 (1x18650, 2xCR123As) and something like my Olight S Mini with angled head, or one of those Manker doohickeys might be neat, but I don’t think that a bigger 18650 jobbie is that much of a hardship for the casual user.
I’m no caver and I’m not a camper, so having to have some external battery pack powering my HL is definitely out of the question.
I have an H03 already, and it is excellent. I actually want a second one for the car glove box, but would happily give an OTR angled light a go too (provided it had similar features to the H03).
