ditto on the fluorescent fixtures with daylight bulbs.
LOTS of fixtures and LOTS of bulbs!!!
Keeping the lights/fixtures close, the light shed will overlap and help to avoid shadows, which makes for a much easier and more pleasant work area.
Add into the mix, more than one switch ... if you don't need as much light, then you can leave some of the bulbs off. However, I did that, and I still find I turn them all on!!!
Because it's bright and clear, because of the daylight bulbs, I can sew any time of the day .... or night!
All of my lights throughout my home (regular bulbs, CFLs, and fluoresecents) have gradually been switched the the daylight bulbs, and what a difference it makes!!! Every once in awhile a warm or cool bulb seems to infiltrate, and I sure notice the difference in the colour given off ...... and soon get rid of it for a daylight bulb!!
