Those look like Moffatt lights... they are some of the highest quality lights I have found and will last for years and years. I only have 3 so far, but hope to add more anywhere I need additional lighting! The ones I use (link above) have a quick disconnect so you can get one or two and move them around the shop if you can't afford too many. It is very convenient.
I then get some 120w LED floodlight bulbs from Lowes and I'm good to go. I use dual lights (one on either side) of where I'm grinding.
yes Moffat, I forgot the name, thank you
