Re: reloading bench
The best work lighting is lots of indirect sunlight.
If there is not enough of that, the next best thing is a blend of florescent lamps, halogen lamps, incandescent bulbs, and different frequency LEDs.
I have spent plenty of time in light labs, but as a power supply guy, not an optics engineer. I can barely convert Lumens to Lamberts.
But I have a friend who has been buying high power LEDs directly from China to make home made work lamps. The single frequency light is terrible for working. He combines the different color LEDs, to improve it, a little.
What you want in work light is a bright, diffused, wide and balanced frequency spectrum.
