I find the central light helpful to visualize powder charges in the cases. I've experimented with the strip light temporarily positioned in a couple places, but cannot find anywhere that seems to add any additional useful illumination. I am running only the center tool-holder "overhead" light, but is is definitely helpful.

The strip light mounts on the inside of the main frame.

Great light helps brighten the loading area up. Works great!

I've been looking for some more light inside of my Dillon loader. This is the perfect fit. One light drops into the center of the toolhead. The other sticks to the inside of the frame. All LED. Perfect! Lots of light just where I needed it.

I installed this lighting system on my press as soon as I took it out of the package, and I'm VERY pleased with how much light it provides over the entire work space around the shell plate. If it is as rugged as the rest of the press system, I'll be ecstatic for a LONG time!
