It has been getting a bit dark lately and my attention has shifted from traction to lighting. It really bugs me to carry lighting batteries when I've got a fat lithium behind me. My lights are 6V LED so I've installed one of these in a diecast box:

...and it took just a week to arrive. The strobe of the LED lights makes it whistle a bit but it runs cool. Quiescent is 40mA @36V, measured efficiency 86% at 6W. Not too bad.
I know it's overkill for lighting, but I hope it'll last. Max i/p is 48V (Caps are rated at 50V). I've varnished the PCB and secured the toroid and caps with silicone.
How does everyone else light up ?
