Hi all,
I figured I'd put all of my shop lighting projects into one thread to save cluttering up the forum with individual projects. This is mostly an electrical thing, but there's some machining in there somewhere
Here are some that I made a while back:
Lightbar (5-6W), uses a 400mA mains driver and 4 Nichia 119 LEDs. They're ~4000K colour temp, 90+CRI, all from Fasttech.com, cost $1 each. They're a bit of a pain to reflow onto stars as they have 2 pads instead of 3 like other 3535 LEDs, but not a major problem.
Converted desk lamp (2W), uses a 5V wall wart in the base, 2 AMC7135 current limiting chips (total 700mA) and a single 119 LED. The head is a bit top heavy, so the next one will get a finned heatsink instead of a lump of alu
Converted drill press lamp (<1W) on my 15in Walker Turner drill press. I've absolutely no idea if it's original or not. This one uses a 12V 150mA driver (from one of those 12V halogen replacement bulbs) and a 12V wall wart
