Making an aluminum box

Nicely done. How about a picture of the lightring?

I'll put up a web page of the whole project when it's casting lumens on the worksurface. Shouldn't be long now. I'm expecting well over

10,000 lux of luminous intensity on the work surface at WOT. (10,000 lux is the intensity of direct tropical mid-day sunlight.)

Mains powered, no battery to change. Line cord goes thru a grommet in the back. Bottom plate attaches with four 6-32 screws into tapped lugs welded into the inside corners of the box.
