Stepped in it last time around with a link, my apologies mods.
For those of you that missed it, I built a LED light for my Lee turret:
Before:
After:
A few parts came in, and I've solved the biggest "problem" with the existing press light systems -- needing some uncommon power source/supply.
Now these are USB powered, so I can use a phone charger or battery bank to power the light. Using a USB battery pack great for my second press that is far from a power outlet works great.
