Bumping an old thread instead of starting another. When I was building Obiwans LS20.1, he had expressed interest in trying to make the flood have multiple levels. While I had made a rough prototype, I wasn't confident in the long term durability and so the idea was set on the back burner and his build had to move forward.
My LS20.2 has been carried just about everyday since I bought it and it was only a matter of time before my interest in making the flood have more levels would be peaked again.
One of the obsticals that needs to be worked around or made different is the small screw that secures the driver/contact assembly to the heatsink. Most drivers aren't small enough to either sit sideways or stacked in order to fit inside the head.
I had a few of the 4 level Nichia 219 L10 flashlights that I intended to keep around to sell to someone in need. Well those had thier drivers stipped from them, stacked on top of each other and wired to work in the same fashion as the original but , with more levels.
Flood first followed by the reflector. The flood is still a high CRI XP-G and the reflector has a Nichia 219 behind it.
So now I have 4 levels for BOTH emitters. Now this light really has some utility!
Tighten the head until the flood comes on and then either tighten and loosen to change levels or cycle the clicky on the C-Pac. Tighten the head more and the reflector comes on. Tighten and loosen the head to cycle levels. If using the clicky to switch levels while both emitters are on, both will cycle simultaneously.
Currently this only works with the C-Pac since the flood stays on with the PD body. This is due to an unintended ground path that just needs to be isolated, then it'll work on the PD again.
The driver assembly isn't the most attractive piece but it fits and the small screw fits just fine. By using a flashlight under the driver to examine the electrical traces on the board looking where a notch could be made, I then carefully used my dremil to make the notch on both drivers to give clearance for that screw.
I see Obi sold his LS20.1 recently. Just figures some drivers are finally available that do what he wanted.:sick2:
