I have some nice fluorescent lights above my bench, but they leave the Dillon's "action zone" in the shadow. Then on the web I saw lights that drop in the toolhead central hole. Brilliant me, I dropped a small maglite with a tie wrap around it in the hole. It was fairly bright, but too much of a spot right in the center, not in the cases.

So, I bought a KMS UFO setup. I'm quite pleased. It gives plenty of brightness and good coverage with even illumination. It's a little tricky to install on the 550C because the press clearances are snug. Don't be too quick to stick down the light strips. Scope out the installation first and then place the strips carefully. Otherwise, you may have some interference.

All in all, it was a great add to the press!
