I have Naked Ladies bulbs. I'd love some Hostas.

do you by any chance have any daffodils to trade or for postage

Anything will be better than what you have now. You can put 4 cool bulbs - and it will work, or mix them 2 and 2. Since T12s are getting phased out - you can replace your fixtures with a 2 T8 fixture as well. Again - you can mix cool white and warm white or use 2 cool whites. Or you can replace it with an LED fixture - Costco has the shoplights for 29.95. To some extent it depends on how cold is your basement - if it is on a cool side - probably keeping fluorescents is better - they do warm the room. LEDs is barely warm to touch. If you want to try T8s - you need to change the fixture - the ballasts are different . In my experience - do NOT buy fixtures in Walmart - they are the cheapest but they do not last. If you have an old style wide reflector fixtures... investing in a new ballast and switchng to T8s makes sense. Then you can keep only one fixture per shelf. Irina, the rewiring hobbyist.

Probably varies by manufacturer. Remove the cooled bulb from the fixture, put a little bit of solvent -- like acetone or paint thinner -- on a paper towel, and see if it rubs off. Or you could try a fine abrasive, like steel wool. If the printing is etched into the glass, you're out of luck.
