Marco Yep they are M bin wg i think
Level 1 Is pretty dim and I would say it is an emergency long runtime mode
2 and 3 are superb with a real nice quality about them .
4 and 5 are amazing .
from my 14.4 li ion pack
at level 5 it is drawing about 2.6 amps
level 4 1.2 amps
level 3 .6 amp
level 2 . 3 amps
level 1 .07 amps
I have no idea yet on how it handles the heat as it has not had a ride yet
but I did some testing with a fan and it on the bars and it semed good.

Hi Trout!
That's a nice setup you've built! The heat is the pivotal point in all of the LED-based headlights...
I have decided to give an inordinate amount of heatsinking to my 3xMC-E's (same as yours, WG, M bin), so I bought a large, 13 x 10 x 6 cm (approx. 5 x 4 x 2,4 in.) HeatPipe processor cooler... :-)
Driving the LEDs on the max. current with a HipFlex, the gills of the heatsink get VERY hot (right now it's 60 degrees centigrade and rising...), but that's inside the living room with no fan to cool it, just giving off heat by radiation and just a little convection. The high temps arrive just at the highest level drive; at level 4 it drops to a more appropriate 41 degrees.
Giving it a little air helps a lot: just by "going" (fanning) at 10 km/h the temperature can be lowered significantly.
I also have a 14.4 Li-ion pack, measured the currents and they are the following:
level 5: 1.94 amps
level 4: 0.9 amps
level 3: 0.44 amps
level 2: 0.24 amps
level 1: 0.1 amps
Here are some preliminary pictures:

The lens needs to be fitted to the front and the whole thingamajig has to be fixed to the bracket which will be holding it on the handlebar.
