I also received 4 of these lightbulbs from British Gas. Also a few months ago some from Electricity people. But each time they were a mixture of the equivalent of 40W and 60W, much too dim for an ordinary room. I put one, the equivalent of 60W in the toilet but why send 4 near useless ones when they could send, say 2, the equivalent of 100W. I know they will say we should use less electricity, but no way am I going to sit in a dimly lit room with the equivalent of 60W bulb. So these spare "gifts" are just piling up in the cupboard.
