Another question: The U2 bin XML on copper - is that the one from ledtech.de ? (As far as I remember) that you wrote about in another thread (I found the best U2 you wrote - or somthing to that effect)
And a third - could you show a picture of the "bypass" operation on the springs? Is that "just" a matter of getting some copper wick/wire soldered to the top and the switch?
Thank you for your time Andi, it is really nice of you to share with us all like this :bigsmile:
Cool! Anyone know anything about Easylightbuy.com? I also found this Ultrafire version at shenzhen-wholesale.com. Think I will stick with the Fandyfire version.
could not insert thumbnails, so here's the link to the gallery
and just a few close-up pics:
With the sony LI-Mn 26650 works great, more then 6 amps maximum. I have to check, if this is healthy for the flashlight... maybe I get a better driver. It seems to be DD on full power. There are three minor scratches, two of them are hard to see.
with a fresh sony 26650, I have measured about 6,6 amps, I think in real life with tailcap it draws less amps (resistance of switch, spring etc). I will see if I get an other driver.
With a half full battery, after 25 mins. tailstand the flashlight didn't got very hot (about 30 deg. C). the battery doesn't get very warm like that.
the 26650 has a capacity of about 2600 mah (last charge with 1,8a). at about 2,8v, it gets darker, and at about 2,74v it switched off. so for a Li-Mn, that's safe (min. 2,5v). But this is just a first look, will have to test more.
So is the 3x XML light from beamtech any good? $50 shipped seems like a decent price. I am looking to get my first multi-led light. Its hard to tell in this thread which light is being talked about in which post sometimes. I don't think 1 X 18650 could really power a 3 x XML light could it?
