looking for a 3a 3v led driver 60v input

[NeilP]

I suppose it all depends on how good the original driver was that came with the light.
XM-Ls are good for 3 amp, but maybe the original driver did not supply that.? I don't know just an educated guess from the measurements and testing I have done with 4 similar lamps in the last few weeks.

I'd test the output from the driver and see what it si actually giving. may be able to get a few more lumens out of it with a better quality driver.

i now opened the new magicshine clones i received. it's horrible how chinese crap can become even worse. once they started copying the original lamps which still as quite expensive, they did i quite well. good quality, good leds, good drivers and proper manufacturing. now they copy the copy of the copy. and it's getting cheaper and cheaper. the heatsink is so super thin and light weight that i don't think that it can handle the job even a little. the heatsink is NOT screwed down to the body, but the reflector now pushed the emitter board down so all falls apart when you remove the reflector. wires are super thin. the driver only outputs around 1a instead of 2.5 to 2.8a. so the light is quite dim.
i now ordered those parts:

as well as those two led lamps to try them out

i hope that those parts will perform better. all driven by a 9v/3a dc/dc converter powered by the main 12s battery

I knw what you mean about crap quality.

I bought two twin LED SingFire head lamps.
nice alloy mating, nice threads, even heatsink was passable.

but the wiring to the battery and control board..what a mess.

I put in two 18650 batteries, 2600mAh, in parallel..so 5.2Ah..so a 5 amp charge rate a just under 1C should have been fine...but oh no..within a fe minutes, it stopped charginign and light did not work. The 5amp charge current had melted all the internal wiring form the charge port to the battery terminals.

as expected

but still advertised as 1800lm it looks to be around 300-400lm max.
ps: of course i know that a single xm-l emitter can't output more than 1000lm - but still it's crazy how those chinese sellers try to cheat ppl.
