I've seen references to led machine lights on here, the latest being Stew's impressive 108 led affair. B&Q are selling 24 led clusters at about £6 each, and I bought a couple today to throw a little light on my Dore Westbury mill - quite a lot of light, actually. Each comes with 3 x AAA cells, but draws about half an amp according to my Avometer, so I'm rooting around my junkboxes for a =>1A wall wart giving either 4.5V (with the lamps in parallel) or 9V (series).
Sturdy plastic cases, and available in black as shown, or in a rather fetching blue. But that would clash with the DW decor.
My hidden agenda for this post is to see if I have worked out how to post pics. If it hasn't worked, then apologies and back to

and

until someone tells me the secret.
Cheers
