I have a couple of W200 heads spare due to the body leaking . I am not sure if this is due to them being bored too deep to take 18650's or due to centerline porosity.
Either way I have 2 heads and you know what they say. Two heads are better than one!
At this stage I am still a little undecided on how to configure it all.
But I will probably go with a standard reflector and XML in one side and a Ahorton Aspheric and XML in the other each driven off a DX 3 amp 3 mode driver converted to single mode. Each will be independently switchable.
I would prefer the switch on the head but not quite sure how to do this.
To convert the DX drivers you remove the mode board and replace it with a 1K resistor. I am guessing if I put a reed switch in line with this resistor it will then turn the light on and off.
