I have 8 halogen bulbs in my kitchen ceiling (Diall 40 = 50w GU5.3 MR16, 760 lumens) and am about to buy another pack of 4, these ones

http://www.diy.com/departments/diall-gu53-40w-halogen-eco-mr16-light-bulb-pack-of-4/237253_BQ.prd

Cheap enough at £5 for 4 but should I get LED instead which seem to be about £7 each? Would they last longer and be more economical? If so, can anyone link me to an equivalent 50w/760 lumens brightness LED bulb? Also, each of my 8 kitchen lights have individual transformers, so will LED bulbs work ok with those transformers?
 
Work out how long it would take to break even, make a saving. Its about 20pence a kwh

I recently changed our kitchen 50w x4 gu10's to dial 3ws £4 each.

I worked it out at 1kw a day at 5 hours so 73pounds a year to run

Leds = £8.76 a year

Also the light is really good. So good in fact Ive now done the whole house in leds.

Looking at the meter looks to be a saving of 20-30% over the whole electricity useage

Bullit
 
For a direct replacement for 50w you would be wanting a 10w led lamps

These work at 12v as do most of them and give out the correct lumens beware of "equivalent to 50w" statments as they usualy never carry the same amount of lumens I personally if it was possible would take out the 12v transformers and fit gu10 lamp holders and led lamps

would think leds would last longer. I got a few eco halogens from tool station they lasted 7 months now have leds

the led hut have a vat free pomo going right now
 
Thanks for the replies guys.

Good link, thanks. Couple of questions.

Your link says 490 lumens but my halogens say 760 lumens, so shouldn't the lumens be the same to be equivalent brightness?

Will they work with my existing transformers anyway?

Around the 500 lumen mark is probably the best you'll get without going up in wattage as the lumens vary greatly between lamps that's why for me I always look at lumen output shouldn't notice much difference it's at the lower wattage led I can notice a difference philips normally work out of the box that's why I use them but if they don't as above put about 2 to 3 on a single transformer but if you have to do that your better off sending them back and doing a gu 10 retro fit as long as your fittings will allow
 
When looking for LEDs for my kitchen I bought one 5w and tried it - it was way to bright - Now have 8 GU10's 2.5w LEDs and they are only 200 lumen and are as bright as old bulbs - kitchen is bright and light but not glaring.

The transformers might have a minimum load so 1 LED won't work with them. You can either either link 2 or 3 together (depending on load) on one transformer or better still do away with the transformers completely and install GU10 LED's.
8 of these http://www.tlc-direct.co.uk/Products/LTSM5WW.html and 8 of these http://www.tlc-direct.co.uk/Products/TLGULH.html will do the trick and will look great.

Great links JohnnyG! Also there's a TLC Direct near me, so no postage. Saw a pack of 4 GU10's equivalent to 50w in B&Q this evening, but being B&Q, I doubt they'll be as good as the ones you linked. Also, the B&Q ones are higher wattage at 6.5w and under 400 lumens.

So I worked out £38.30 inc VAT for 8 of those TLC LED bulbs and £16.80 for 8 of the TLC GU10 lampholders. Not too bad. I'll have to get my guy in to fit them as I not too hot on electrics. So all in probably around £100 fitted, give or take.

Wanted to check something. Will the LED bulb slide into my current bulb holder easily, same as my Halogen bulbs? I'm guessing it should do. There's a rounded springy clip that the bulb slides into. In other words, I shouldn't have to change any of my light fitting metal surrounds, right? Here's some pics. You can see how they clip in to the holder.

Interesting. Ah well, I'll still go for the 5w LEDs, I don't mind if it's extra bright. :p
 
The lamps I linked to are the same size as standard GU10's but have a slightly more convex face, they fit in GU10 fittings fine.
They are the same width as MR16's so will go in your fitting although you may have to persuade the holding clip a bit.
If you're going to TLC just take a fitting with you to check, they're very helpful in there :)
