Here's the photo of the proto for the L1P and L2P 3-stage circuit:
The circuit will NOT use drop resistors to reduce the output. This design uses the leaf spring switches to actually change the level of current going to the Lux by modifying the feedback to the controller. This method is very efficient for all levels. This means the runtime for lower levels will be about double compared to using drop resistors to drop the switcher out of regulation.
