does an 18650 light with magnetic charger and multiple levels exist?

    I was wondering if anyone knows of a dive light that runs an 18650 battery, has a magnetic charging system and has a high of like 1000-2000 and a low of around 500-600 lumens?


    something similar to this Warrior X? but in dive light form.

    a single 18650 can't drive 2000 lumen. That one claims it can do it for 1.5mins which is about right, but at that point in time the battery won't be able to drive it any longer, and the emitter is going to overheat on land.
    What benefit does the clip charger have for you? The charger on that charges at 1a, so it's going to take about 4 hours to charge the battery with their clip thing. Fine for land use, but if using it for diving you'll only get the single dive out of that light.

    1000 lumens would be more than enough. I just wanted to give a range. and a magnetic charger would allow charging without breaking a seal in a damp environment.

    @ekremer since the charging is so slow, why does it matter? It's one thing if it's a 30-60 minute charge time where you can charge it during a SIT, but with a 4 hour charge time, you're not going to be leaving it damp while it's charging. I've never had an issue swapping batteries out even with wet hands then you charge everything when you get home.
    Of note, the magnetic charging is going to lead to galvanic corrosion while underwater unless expensive electronics are put in there, and even then the contacts would have to be gold so they don't corrode naturally. UWLD has their SECS charging system, and Light and Motion has it in theirs as well, but the cost to implement that into cheap backup lights would be impractical.

    This is as close as I think you'll get.
