Got my new 4 led light, works great, in fact works better than the 1 as its a bit less "spotty" (and dammmmm its bright) i was expecting different modes to run with 1/2/3/4 leds, but it seams high is full blast on all 4, and low is just running all 4 on a lower setting. I never bother with the strobe mode especially in poor lit areas, as i found it makes things appear a lot slower than you would expect and i crash LOL it does have its use for pointing at the ground when commuting on the road as the flashing is more than enough to get car drivers attention (just don't aim it upwards or they will run you over)
Never tried it for any legnth of time yet, unsure on battery life, i would expect it to be less though (i was getting 3 hours + from the single XML led) Its a shame it does not have a super low mode of just 1 led, so you can still get 3 hrs + from one charge, but.....
I tried my new battery pack with my old light and it switched on for around a second before it went off, i started to investigate and it looks like the led driver board is toast on my old lamp
plus point is that the battery pack is fine, so i now have two of them and can keep one in the back pack as a spare.
A lot of the time on club rides i turn mine off completely as its not needed unless we are deep in the unlit woods!
One chip on the old lights driver board looks a little damaged and it has that kind of "burnt electrics" stink about it, i would quite like to resurrect this as a little project and had a quick look on ebay for cree led driver boards, but i am gazzzumped on all the different options (saw some for about £1.50)
a lot of the boards i looked at seam to be for 1 single battery (not a pack of 4) and i am a little bit confused on how to change the mode, i dont care if the thing is stuck on high as soon as its plugged in (in fact i prefer it) but all the led driver boards i looked at dont have the little switch on it (i think there for torches)
Anybody played around with these internally?
