Remote battery head unit upgrade?

I have been using a cheapo 2 emitter head unit with remote battery (8.4v) for night trail riding. Works ok, is very light on my helmet weight wise, but the battery was the limitation.
Like this: Amazon.ca

I bought a case that allows me to run up to 6 18650 rechargeable cells, so I feel like I have solved that issue. Now I am wondering about finding a better head unit (is that what I would call it?). I’d prefer to just find the light part and not buy another battery….but just looking for an optimal 8.4v light that uses remote battery.

Would this be considered a headlamp and this would be the right place to ask? I see all sorts of versions for bike handlebar mounting with crazy numbers of LED’s but I would prefer to be advised by someone that knows something rather than rolling the dice.

OK, down a rabbit hole! Can someone help me choose something? I don’t want to fall for sheer number of LED’s…there must be diminishing returns!

I see you found the mtbr lights and light riding forum - they should have better suggestions than this forum for bikes. I consider that type of headlamp when used with a good headstrap to be the best form of headlamp for moving: trail running/skiing/cycling. But remote battery lights aren’t discussed much at BLF. The remote battery lights are also getting less popular at mtbr now, but they make sense as helmet or headstrap lights.

My Yinding with neutral white XM-L2s just died this season after about 5 years. That was a good inexpensive (~$30 head unit only) option, but not made anymore (or hard to get at least). I’ve also had the older version of the Gemini Lights Duo and another older Gemini, as well as the original popular Magicshine from about a dozen years ago. I’d look at the Magicshine MJ-9 series. If you want to spend more, check out the Gemini Duo, Gloworm Alpha (gen1), and Lucifer M6.

Thanks, yes I posted there as well. I may be looking for a unicorn of reasonable price and better than current without buying battery. The Lucifer brand is interesting and different! The Magicshine monteer also looks good. The Gemini and Gloworm are very similar with the 2 emitter designs….like the basic one I have now.
