I'm looking for a light that could mount to a handlebar but also has a strap to attach to your head so you can use it to run and hike with or to change your oil at midnight. Also, I'm a fan of a rechargeable light. That is, I'd imagine the weight of batteries on a head-mounted light is appreciable. Logical?

Also, how many lumens is necessary for a night run/hike/oil change - or do they all shine plenty of light?

Thanks!

MagicShine. Action LED sells them, and the head-straps, helmet mounts, etc. High power is claimed at over 800 lumens, but most testers say actual lumens is closer to ~500. I need more light than most. I find one MagicShine just adequate. Most will find it plenty of light. For hiking/working on the bike/working on the car, you need less light. In any case you cannot use the default high power setting unless you are moving at bicycle speeds. The thermal protection circuit shuts the light down if you run the light on high power for more than about 5 minutes on high power just standing around. I find the lowest power plenty for doing stuff in the dark and the middle power setting is brighter still and does not trigger the thermal protection. What more do you need to know? Get that credit card out already. Do I need to find the link for you too? Ok, here it is: BIKE LIGHTS ? Action-LED-Lights

Ya, I actually hung on all the way to the link. Thanks, Leis... Great site and lights.

Lupine makes best light for your needs. The big issue with cheap lights is overheating due to poor quality drivers being used to make lights. Once the light overheats it steps down, some drastically until the unit cools off then steps back up. Ok on a bike moving in cooler temps but on headband it is a big issue as very little airflow compared to on bike. Lupine makes best quality and you will only ever need to buy one.
