Thread: Most lumens single emitter headlamps

  1. #1

    Default Most lumens single emitter headlamps

    What headlamps are out there that offer the most lumens without stepping down the output? Needing a headlamp for mountain biking & off-trail hiking/navigation. Seems like there are some decent outputs around 2,500- 4,000 lumens but they step down in just a minute or so which sounds annoying for technical/dangerous areas. Must be fully waterproof as well.
    Currently looking at Thrunite TH30, Olight Perun 2, Nitecore HC35, Zebralight, Fenix, Acebeam, etc.
    Because I need something super durable, I am leaning away from headlamps with cords.
    The Olight proximity sensor sounds like it might be dangerous. Does anyone have experience using it while navigating through heavy brush with uneven ground in which you need extra light? It would also be scary if the sensor dims the light on accident for leafy plants or rain at speed while mountain biking.
    Any thoughts or suggestions?

    Hey! I use a Petzl Swift RL for night riding. I also run a light in my handlebars so that I can see where my bike is heading and I can look up to see where I want to go. Hope this helps, and happy riding!

    Klarus HA2C 3200 lumens 18650 headlight. Use it at 400 lumens or lower and you don't have to worry about stepdowns. Most lights you'll get a max of 300-500 lumens if you don't want it to step down. 1000 lumen setting will work okay with airflow from bike riding. If you want higher constant brightness, get a bike mounted light with a big heatsink.

    Cool light, but it isnít close to being waterproof enough for me. Nice looking light, but I know I would kill it.

    If you need truly 2500-4000 lumens without stepping down, then lamp must have its mass and lot of cooling fins.
    Without any promoting our lamps, here is example how massive fins must be there to cool down properly 3200lumens. Inside, there are 4 current best XP-L2,V6 leds, copper board and efficient electronics to eliminate all heating and still in 20C degrees ambient without any movement it overheats after 4 minutes. This lamp cools down properly in 20C when you run, even slowly. When in lower temperatures, its much better.

    I wanted to say, that you should either think whether you really need so large light output or be prepared that these high lumens are only for few minutes until they stepdown because of high temperature. Also I think that cordless 21700 powered headlamp is quite front heavy for off trail hiking. Better when the weight is distributed between front and back but you wrote that you dont want cords. So as a compromise, I would rather use 18650 format.

    Those are two very different uses, calling for two different setups
    Anything suitable for mtb is going to be massive overkill for bushwhacking in terms of size, weight, and maintainable brightness. Plus, it will need to be helmet mounted, or a helmet mount + bar mount system vs. a headband.
    I'm all about the neutral tint floody Fw model Zebralights for the hiking part, but for mtb, I'd be looking at stuff like the Gloworm X2, XS, XSV, etc. Gloworm has multiple emitter lights with changeable optics(like spot/flood/"wide"), so you can mix and match combinations of them to your trails, and use battery packs with 2 or 4 18650s.

    I envy you the mountain biking. Don't think I've ever been so passionate about anything, but had to give it up(trying to avoid a triple anterior fusion for my "90yr old" back, per the orthopedic surgeon).
    I don't suppose you want to buy a medium Canfield Riot?
