After googling how much power various electrical items use,
I read that a TV on standby uses 80% of the power it would use if it was turned on.
I have a mains smoke alarm with battery back-up which has a green light on permanently and a red light that flashes every 30 seconds. Just wondering if a smoke alarm 24/7 uses more power than a TV. Does it?
I was only wondering because if I go into the hall at night I could read a newspaper under the green light glow from the smoke alarm. It seem unnecessarily bright.
I get electricity and gas from EDF.
My quarterly bills from 6th Feb - 9th May were:
Very reasonable I think. Mind you I'm hardly ever home.

Combination boiler has halved my gas bill.
I've got a related question - would be grateful for an answer. I have a similiar kind of mains-powered smoke alarm, in fact two or three of them. All fine, except that the one in my bedroom, over my bed, keeps me awake at night - for the reason Phoney mentions - that LED is insanely bright. Given that it's obviously a bad idea to cover the thing up, I'm pretty keen to figure out a solution so I can get a good night's kip. (And eye-masks slip off during the night, so they only work for so long.)
Can anyone advise on how to remove the LED bulb, or at least get to it and safely cover it up? (Blu-tack, perhaps.) I can't even get into the smoke alarm to find the bulb. I already know that the alarm bleeps perfectly well when it's running low on battery, so I don't need the LED bulb as a low/dead battery indicator.
