Thanks.

.......snipped......

I also have 3x40 incandescent in the dining room and lounge both on dimmers which reduces the wattage.

Beware of assuming that dimmers save a lot of power; they slice up the leccy sine wave and apparently the consumption is read by the meter as being quite high still - maybe someone could prove this by trying power meter on thair system (I got rid of all my dimmer switches so can't test this any more).

See paragraph near bottom of this web page:

Quote: "yes, less electricity is flowing from the mains into your house. However the question is though whether your meter can measure this reduced power consumption. Depending on your meter it may not see any difference. This is partly because dimmers also cause the voltage and current to be slightly out of phase."

Interesting

I made my comments based on the redings given by my energy monitor which shows a 40+% drop from bright to TV ambient on 3 x 40w load.:think:

For TV ambient, I discovered neat round 5W (equiv about 25W) energy saving bulbs in Wikinsons. I never used those back wall lamps on full power anyway.

Each light does have it's own switch so I can turn the one off behind the telly and saveanother33%:)

These could also be replaced with 28W halogen bulbs, such as the ones from Phillips and Osram which are contained inside the traditional shape outer glass bulbs and come in a range of bases to fit different fixtures. They produce the same amount of light with less energy used and the dimmer would still work fine too.

I have a few table lamps with inline dimmers and like being able to adjust the brightness, which is why I've been using these. So far nothing else I've seen dims as well as these halogen replacements, and although not the most efficient bulbs available they are 1/3rd more efficient and come in higher wattages to replace 60w (42w halogen) and 100w (70w halogen) bulbs.

I'm thinking of changing some of the bayonet bulbs that I have to LED also... I have found Bayonet to GU10 converters, has anyone used these before? Do they work ok or I am just better off buying Bayonet LED bulbs? I just like the light from the GU10 LED's that I bought and would rather use them if i can.... any ideas?

I have just received a batch of Halers EvoLED and these are going into a new vaulted ceiling. Each of these units cost me over £40, but I can honestly say they are high quality.

These are rated at 425 lumens, they seem subjectively as bright as a 50W halogen, but only time and experience will truly tell.

I recently had the ceiling in my kitchen replaced and took the opportunity to put new lighting in. The electrician strongly recommended the Haler EvoLED; they certainly are of a good quality build and come with a 7 year warranty.

VERY pleased with them................

So having successfully fitted new LED bulbs in my kitchen and being very impressed, I've decided it's time to do the bathroom. Pulled a bulb out to check it was GU10 and it's not, it has a different connector, more like a sharp prong, i think they are called MR16?
Anyway, i understand these bulbs each have their own power supply etc so want to change these fittings to GU10 so I can get more of the led's i used in kitchen.... any idea how to do this?

My 9 kitchen MR16's are in sets of 3, with one transformer per set. If yours are similar, you'd have to get into the ceiling space and rewire to each bulb - probably drill a larger hole for a GU10 too. Bit of work to do and is probably affected by regulations so might need a qualified sparky to do it by the book.

Hi Victor, thanks for the reply. Mine are spaced out and from having a play, I think each individual bulb has it's own power supply. Any idea how big a job it is for a sparky? Only 6 downlighters in total. Expensive job or not?
