If not, they'll have to change the name......0

Yes in the long term they do as they consume less energy and thus this will reflect in your energy bills, I think it tends to be round £5-£7 per bulb which would depend on the room and usage.0

I moved into my house 8 years ago, and bought energy saving lightbulbs for every room.
I have never had to change a lightbulb yet!:j:money: Martin Lewis Rocks!:money:0 -
Hi,
yes they will save you money, plus they last longer, and they are getting even cheaper now, less than £1.0 -

Energy saving light bulb 20W (same light as 100W conventional)
20W X 8000 = 160000W = 160kWh @ 10p =£16
plus cost of bulb £1.00: TOTAL COST = £17
Conventional 100W light bulb
100W X 8000 = 800000W = 800kWh @ 10p =£80
plus cost of 8 bulbs @ 20p each = £1.60: TOTAL COST = £16.20
Two slight disadvantages with low energy:
1. They take a couple of minutes to get to full brilliance;
2. Most types cannot be used with dimmer switches
Don't worry about switching your TV off "standby" - change the light bulbs !
I think you need to re-do your sums0 -

I heard someone giving money-saving advice on the radio recently (no, not Martin:rotfl: ) and he said don't use them for areas which are switched on regularly for just a few seconds/minutes(such as hallways etc) as they cost even more than normal bulbs(
) in the early stages powering-up so would be a waste of money. Also. lots of switching on/off shortens the life of the bulb so not much gain there either.
I'm not sure I understand it myself:o but that's what was said and why I didn't buy any for some of our fittings,0 -
i have to say i love them for when u wake up in the middle of the night and need a wee, those few secs it takes it to warm up means it doesnt hurt ur eyes when u turn the light on in the hall0

Morrison's supermarket are currently selling Phillips energy saving light bulbs for 39p each 11 and 18 watt. They are the neat little ones, but you must get there quick after a delivery as the baton fittings sell like hot cakes leaving only the screw fittings0

Yes they do use a lot more power when starting up so I hear but is only for a very short period, and your more likely to have the bulb on for more than a few secs for a hallway, many households seem to have hallway light and particularly landing on for hours on end even through the nightI heard someone giving money-saving advice on the radio recently (no, not Martin:rotfl: ) and he said don't use them for areas which are switched on regularly for just a few seconds/minutes(such as hallways etc) as they cost even more than normal bulbs(
