Had "most" of house re-wired about 2 1/2 years ago. I have in the kitchen 2 light bars, each holding 4 GU10 halogens. Now, the problem is they blow bulbs on a monthly basis. To the point I currently have 3 out of the 8 working! Is there any reason that anyone can think of? Maybe the kitchen lights wiring was not replaced and is not up to powering halogens?
The other problem is, as said I have "most" of the house re-wired. The little waste of oxygen that did it only did about 3 quarters of the house and decided to double his quote. So I kicked him out. So I dont think the kitchen light suppy wire was changed. Kitchen fully on seperate ring etc etc just getting fed up with buying light bulbs as part of my weekly shop.

Any advice recommendations welcome.

I used to have that problem, in my case I think they were overheating as since I changed them to 35W from the 50W's I now lose very few.

My experience of GU10 bulbs has also been poor, they fail faster if you get finger prints on them so only touch via a soft cloth.

I cannot see the supply affecting this.

the gu10 lamps, go often a quickly, it can be down to some many factors, i would recommend replacing the lamps with GU10 Compact Fluorescent Lamps, Pack of 10 GU10 Compact Fluorescent Lamps - 9w | eBay UK

what make and how much do you pay?
I have noticed the cheap unbranded ones go quickly, the slightly more expensive ones do outlive them.

Agreed, cheap GU10s go quickly. I'm now using these +/-3.5W chip LEDs and they are great, and super efficient. The light they give doesn't suit everyone so try one first.

NTDWM by the way.

The GU10 Compact Fluorescent Lamps menrioned will work too, but, you need the deeper light units to take them as the compact bulbs are longer then standard GU10s.

Life varies enormously between brands the biggest name brands aren't always the best.
For longer life I have a mixture of halogen and LED lamps in my G10 fittings and have found the life of Phillips LED lamps have been very disappointing.

hmmm - I've been looking at low(er) energy replacements for GU10s. We've just done some redecorating etc. and replaced a 4x 20W (I think) 12V unit with the bulbs with 2 pins for a 4x 50W GU10 24V unit. I immediately noticed that it's like a sunbed under the lights so I wanted to look at alternatives for both heat reduction and energy saving. Questions in my mind were:

Fluorescent

Lower energy
Physically bigger so probably would not fit my lamp bar
Also quite expensive

LED
Lower energy
Maybe not quite so expensive
Are they the same size as normal ones?
Light quality - I agree about trying them first, but are "day white" or "warm white" better? what's the difference, given that at the moment the bulbs are effectively spots over cooker/sink area?
Also, what's the difference (price, light quality, life) between the chip LEDs and the bulb LEDs?

Also, I just noticed that those chip ones have a beam angle of 120 degrees - most of the others I have seen are around 40 degrees. Do the bulb ones have a tighter beam?

hi, i have found that the led ones, nobody so far has like the type of light they give off, suit an office.

the beam, is on a normal one is quite large, the 40deg one will be more of a focused light, to light up a feature.

the gu5 (12v) lamps are better that the (gu10), they last longer, but are more dearer to fit to start with.

regarding your lamp bar, can you post a pic up? or a link to one?

The link I put on was to 50w equivalent led bulbs, they are not 50w - they are 3.5w. Go for warm as the bright wight are quite blue in my opinion.They do tend to give a wide beam so go for narrower angles. They are the same size as 'normal' GU10s, I don't have experience of the longevity as I've not had one fail yet. I was not sure when I fitted them - the light is 'different...' but I don't notice it now. They are also cold so no 'sunbed' like heating from above.

If you do decide that GU10 CFLs will fit, look out for the 13 or 14W versions, the 9 and 11s seem a bit weak after 50W halogens. Also look at a mix of CFL and halogen or CFL and LED, as if you're anything like us, you'll pop in and out of the kitchen for things and the poor light of cold CFLs isn't good. They are however very good for bathrooms, as they are not such a shock to the system when you switch them on, bleary eyed, in the morning
