I like the 4" LED fixtures I bought at COSTCO for general lighting. White painted walls and ceiling help too. However nothing is better than the daylight from the double window near my bench. It is diffuse but directional and casts enough shadow to clearly see scribe lines and features. At night the overhead has plenty of light for general tasks but I have a harder time seeing some details without a little shadow. I have a track light over my window with 4 reflector bulbs (LED floods I think) that I use when carving or doing hand tool work. I will even turn the overhead off when doing this to get a little more definition. I also have some cheap (IKEA) goose neck LED lamps that I can use to good effect for things such as hand saw filing.
