it seems with all those really cheap (
You get what You pay for, but most of them still work ok) lights from chinese shops like dealextreme, most ppl suddenly "need" the latest high power leds run on full power (~700-900 Lumen) or multiled-setups which are even more powerful.
🙄
For me, I already was perfectly satisfied with the previous single-die led (~200 Lumen) and now these lights offer around 300.
This is a "typical", small, single 18650 flashlight, offering a runtime of about 2 hours; clamped to the bars.
This were any 1*18650 light You read in here.
(extreme cheapo offers will be about $ 50,-- including light, batteries, charger, bar holder)
to see the general idea:
open
www.dealextreme.com and klick "flashlights" and then "18650 flashlights" for the flashlights,
or "sports & outdoors supplies", then "bike acessories" and "Bike lights and electronics". there something like the Magicshine MJ808.
PS: Last weekend we did a difficult trail snow ride, where I lent around 2 of my 1*18650 lights and had mine run on medium power (nailbender XM-L P60 insert) and that was totally ok. There simply is no real need for more power.
* "real" bike lights (XM-L on full power with external battery) are too big to bring more than one.
Also they are "single-use" items, as they can only be used for biking, while my flashlights see some use very often.
Of course my personal requirement is
small and
bright enough, I m more the backpacking guy
