    LED pixel boxes. Not retro, but something I've oft considered building myself!

    Yep - something like this:

    2A per channel at 8-16V output should do the job for a pair of boxes maybe. Can also ditch the Bulgins and the heavy mains cables too. If I were looking at a conversion project I'd probably start here but as I suspect Wayne has already put a fair bit of time, effort and s into the existing conversions a handful of resistors is probably the cheapest fix.

    2A per channel isn't a problem. The LED Harlequins I use equate to .01A per lamp.
    The 8-16v is the big problem there. I've shelled out a couple of hundred quid on the 240v versions

    I thought you might say that... which lamps are you using?

    For the dozen or so in the inifinity tunnel, standard incandesent 25w Harlequins just to drain the residual current
