Yes siree Mr. RainmanP sir, I saw your original post regarding the Optronics lights and, truth be told, if I were embarking on this journey now I would likely go that route. But since my contraption was already put together by the time I found this thread.....well....
My lamps are MR11s. Since I've already got them, I think I'll go ahead and try to use them.
Hmmmmm, this commuter mug here could be retrofitted to house an MR11 with a switch in the snap-off-cap......hmmmmmmm....
