1 - Can I use them upside down? Like in a recessed ceiling light, which I keep putting off changing because I hate step ladders.
2 - X-10? I know I read that they work with the appliance modules, but do any work with the lamp modules?
3 - Ceiling fans - I have one that takes the little intermediate base bulbs that are difficult enough to find. Do they make CFL versions? And also curious, the fan manufacturer says not to use >40 watt bulbs, but since the CFLs use less electricity, can I use a brighter bulb?
4 - "Touch" lamps - would CFLs work with them? The lamps I have let you adjust the brightness by how many times you tap the base.
