    Jeepers creepers. $8.59. Mondo bright, multiple modes: 3 light levels, flashing strobe and SOS. "Survival" flashlight, powered by one 18650 rechargeable Li-Ion. Blindingly bright on high. Ridiculous. Would make a great headlight for a security bot. erco-approved.

    erco I have a flashlight with a Cree XM-L T6 led and it takes 2 Li-ion 18650 2400ma 3.7 volt cells in series, has the modes you describe above and it is BRIGHT! Here's the datasheet for those LED's.

    I've been trying to figure out the difference between the 502B erco linked to and the 501B which is only $5.55 and includes two batteries and a charger.

    Any reason why the 2B version is more expensive than the 1B?

    Your link is to an auction (currently $8), not BIN.

    I keep forgetting ebay also has auctions. I get used to buying cheap Chinese stuff with a set price.

    One comment on the Amazon site - so maybe not such a good deal..

    Yes, I saw this guy's review, where he noted that it was a ~500 lumen light, not 900. http://www.youtube.com/watch?v=JI7Ltv2U5AU

    Nonetheless, a blindingly bright light. And as the fellow says, the strobe mode is very disorienting. Could be a useful defensive weapon in certain situations. Jeepers, now I'm starting to sound like a survivalist... "Sure, you can take my flashlight. When you pry it from my cold dead hands!"

    I'll have to do some battery life testing to see how long my Chinese Li-Ions (is ChiLi-Ions trademarked yet?) last.

    Well guys I find these LED flashlights great when you want to illuminate a tiny spot, if you could find that spot that is. In the movies you always see how they search a dark room with their pencil beams always missing the danger in the dark.
    I've made my own using cheap 12V 5W LED reflector lamps (40 degree) powered from a 9V NiMH but I plan to do a small inverter PCB so I can use a couple of common AA NiMH instead. I can shine this across the road and spot all the possums in a gum tree in one go (Gidday fellas) or just light up a room or even on occasion a carpark , either way it is very useful. I have other lamps which are brighter still.

    I always buy the lights the LEO's have. They always have the best stuff, and it is field tested; the hard way.
