    Is there a way to use dimmers with low energy lightbulbs?

    As title. I tried changing some old style ones with new low energy ones in our hall lights today and they crackled and sounded like they were going to explode. Ended up changing the switches as well.

    Good question, I switched back to normal bulbs:thinking:

    you need to get the special ones which are dimmable

    dont install low voltage transformer fed lights, use dimmable 240 v:thumbsup:

    and therefore probably cost accordingly?

    this may not help much but, i am doing quite a bit of electrical work on a new extension, i am putting in all rooms 20w/240v dimmable halogens,
    i think they way forward. all dimmers connected to flourescent type lights will be expensive, impossible or a pain in backside to do. as a general rule of thumb dont try and use dimmers with them:thumbsup::thumbsup:

    dont think they are extortionate, but obviously more then standard ones.
    have a quick search on the net and see what prices are like.

    I saw dimmable halogen low energy lamps in Tesco today,they were either two for 50 pence or two for a pound.

    dimmer energy saving bulbs are generally around the £10 mark, wait a while and the price will come down.

    Yep, the halogen ones are the only economical dimming energy saving bulbs.

    Cheeze: Dont forget thoug matey, you will need to have atleas 2% of the new lights in your extension as low energy, bilding contrl or something like that, although I am pretty sure it covers the whole house, so if you stick low energy lamps in all your normal stuff, you'll be fine having halogens in the extension (although not 100% sure right this minute :p) Just got back from a long day at MCM in London, followed by a 4 hour marathon session on a private hire boat along the thames with 200 other like minded souls
    Will check me regs book tomorrow (if you remind me) and see what it actually says.

    they will not be low energy. they are just basic gu10 halogens (probably 50W).

    Not when they will get banned eventually too.

    Dimmable CFL start at £8 each and much less when on offer at supermarkets. (from £5 deld on Amazon)
    Last up to 10 times as long and save towards £750 each when assuming a 10,000 hour life 100 watt equiv output using 25% of the energy of a normal bulb.

    A standard 100W incandescent bulb will probably use towards 80 watts at its dimmest setting.

    Some of the dimmable CFL's also have their own dimmer meaning you double flick the power at the correct brightness.

    The problem I'm having is finding dimmable, low energy, E14 (small screw fitting) bulbs. I've bought some lovely new lights but if I use the old style candle or golfball bulbs even at 40W bulbs I'll be using 8 x 40W = 320W all the time they are on. Hence the need for low energy ones. 8 x 7W = 56W, huge difference! I'd like to be able to dim them but I'm not prepared to spend £5-£10 per bulb as it'll work out cheaper using old style bulbs instead.

    Just to reiterate what i posted, i actually picked up these low energy dimmable halogen bc lamps and took them out of the box to inspect them as i had not seen them before.I can also confirm they were either 50 pence for two or a pound for two at tesco lee mill.
    I have been an electrician for over 35 years and i do know what a GU10 is!

    LE GU10 can still consume 40W to give out 50W light so hardly low energy!
