We have 12 volt led strip lights in an off grid cabin. These are adhesive backed strips that run across the cabin on the truss bottom chord, exposed truss ceiling, 4' centre trusses.
After years of struggling with various expensive battery light options, non of which really worked, the LEDs have been a godsend.
As Graham says, it's the total lumens that make the difference, not the light colour choice. These are in warm white and on a dimmer. We run them at about half power. On full power it's light enough for surgery, although we only have fish knives there so we avoid that.
The warm white seems a little easier on the eyes, or maybe it's just similar to what we are accustomed to with incandescent. For a workshop I would be happy with cold or warm white as long as there is plenty of it in assembly areas.
