After posting this morning, I went to our local electrical supplier, and asked about shop lighting. Specifically, high-bay LED lights. I know, I can order from Amazon, but I wanted to get my hands on one and take a look at it, spend some of my money with the local folks, and educate myself.
They sold me something by ASD Lighting (asd-lighting.com), their UHB5-PRO series. $139.00 out the door. I installed a plug, got out a ladder, bung it from a purling, and asked Belle what she thought. Of course, I had to move the ladder and re-hang the damned thing, but that's how things go in a well-run household. I have to admit, she was right.
That brightens things up a bit. The boys had been complaining that the gun cleaning table was a bit dim, They won't be able to make that complaint now.
And, now that I've educted myself, I can go to Amazon and save a few bucks.
