We have two light fixtures in our laundry room (the basic kind with the bare light bulb). The other day both stopped working. I checked the bulbs and they are good, and I used an electrical tester to verify that there is power to both fixtures when the switch is on. What else could cause this? I am stumped. Thanks.

I got two kinds of fluorescent white paint. One is supposed to be very vivid, and it's more expensive. However, the more expensive one is actually a lot dimmer under my black lights. And they both have a blue/purple look. So, could this be because my blacklights aren't high quality? I've looked at them under two blacklights. One is just a compact fluorescent blacklight. It actually has the phosphor of a regular white fluorescent bulb, just covered with dark glass or paint. The other one is a shoplight with two GE 4' F40T12 fluorescent blacklight tubes. I'm not sure actually if that has a special UV phosphor or not. Is there a better quality of tubes with phosphors that would work better with the paints? I'd like to do blacklight art, so I want good, true colors and a light source that's putting out very little visible light. Can I get a good quality blacklight fluorescent that's compact, so it would screw into a regular light fixture? Thanks, Laura
