I took another trip to Home Depot during lunch today, and they had one set of Daylight bulbs with enough output to suit me. 23 watts = 90 watts incandescent. So I snapped them up and installed them into the overhead fixture in the sewing room tonight. Much better! The fluorescent Soft White bulbs were the same wattage but the quality of the Daylights is sooo much better--no yellow, so much kinder to the eyeballs. I even did a little mending on black this evening. Hopefully this will open up whole new opportunities in sewing.
The old bulbs will be relegated to the sconces on either side of my garage door, where they'll save me having to replace bulbs out in front of the house all the time.
