mattwnz: It does make me wonder though how you can sell IC light fittings that are designed to olnly take energy savers, when there is the risk that someone may install an incandescent in them, due to them having standard b22 and e27 fittings in them.


By labelling the fitting, which requires testing that the label has permanent adhesive and will last sufficiently long.  Often he label gets changed to something cheaper after compliance testing, but then the liability lies with the manufacturer and not with you.  After the fact it is also really hard to prove that the label fell off, when the house went up in flames and no evidence is left apart from the end used used the wrong type of bulb.

It is stupid, but that is how it works.  We have pendant light fittings that are (was) labelled 60W max, but you can physically fit anything.  I have also seen on (think it was) Philips LED bulbs the packaging says do not use in pendant/recessed fittings.
