I use a well lite area on the workbench and magnifying lamp.
John, I recently installed (2) 22" LED ceiling fixtures to replace (4) round 4-bulb fluorescent fixtures, the ballasts kept failing and cost as much as the entire fixture. I probably need to get 2 more, but where my work area is is directly below one of the LED fixtures. Between that, a magnifying lamp, and my optivisor I could perform brain surgery it's so bright in there! I'll eventually replace all my lighting with LEDs.
Thanks for the tip about opening up the holes
