I'm considering buying a Home Easy ceiling rose, as my light switch is in awkward place and I'm unable to move it. I have an LED bulb in the correct socket, and this manual says you can't use fluorescent bulbs, only incandescent. However it makes no mention of LED bulbs. Is it safe to use an LED bulb in such a socket?
There are a few reasons you might not want to use an LED bulb in a fixture:
- If the fixture is dimmable and the LED bulb is not, the bulb may flicker or not come on.
- If the fixture is enclosed, an LED bulb may overheat. (LED bulbs generate much less heat than incandescents, but they do generate some... and they're a lot more sensitive to overheating). Some LED bulbs say they're OK in enclosed fixtures.
- LED bulbs are often larger (even if the mount is the same), so an LED might not fit.
- If the fixture or circuit runs a small amount of current through the bulb at all times, this can cause a LED bulb to stay lit. This is usually an issue with light switches that have some electronics in them and don't have their own neutral (e.g. a timer or night light). I can't really tell what's going on with your fixture, but this might be the reason.
If the LED bulb is dimable it might work.
Typically when you see incandescent only it is modifying the AC wave form. Incandescent bulbs don't care and can work over a pretty broad range. Where bulbs that have a solid state controller or transformer in it are pretty limited to a standard AC wave form. And if that LED/CF bulb can be dimmed, they they can handle the most common type of AC dimming only.
