My 8' workbench has a pair of 4' 6 LED bulb fixtures from Envirolite mounted to the ceiling above it, 20,000 lumen between the 2 fixtures if spec sheets are to be believed. The first fixture I got from Homedepot.com, the second came from a different online presence as HD was out. SWMBO says it like having the sun in the office. I have the same old eyes as you and I like lots of light on my work area. My bench has 3 adjustable shelves attached to that is why the lights are suspended from chains from the ceiling. The top shelf isn't really lit that much, but that shelf is basically for storage.
