My porchlight burned out and I went to Home Depot to get a replacement bulb. The previous one was a sort of torpedo-shaped fluorescent arrangement branded "Lights of America" and, as I recall (it's been several years), rated for outdoor use. The Home Depot fella told me I was imagining a light specifically rated for outdoor use -- that any fluorescent was fine, and pointed to a shelf. I bought a small twirly-tube thing that cites a "minimum starting temperature" of -20F. The front panel says "Usages: suitable for totally enclosed fixtures" with 2 little pictures of a lamp and a ceiling fan with lights.The porch lamp is not "totally enclosed" enough to prevent a rain of dead moths from falling on my face as I removed the plastic panel bottom enclosure. It's outdoors on the porch ceiling, not "enclosed" in the house.
What does "totally enclosed" mean?
