I currently have 2 light fittings (bathroom and utility room) with conventional 50W GU10 bulbs. These run hot and don't last long, but I have avoided LED's until now as the output seems to be so poor and the cost so high.
Can anyone recommend a suitable brand that gives a decent output, doesn't cost a fortune and will have a reasonable life expectancy?
Second question-is 6W LED the approximate equivalent of 50W? All the ones I can find seem to be rated no higher than 4.9W.

Done all that when i had new kitchen extended and spots all over giving out loads of heat and barely see my hand in front of my face

Ended up going back to florescent lights

2 x these in the kitchen to replace spotlights

60 watt x 2 tubes and the light output is just immense by comparison - we have been well pleased

we have put something similar but smaller in the bathroom and the whole place is just brilliant as a result

Thanks for the info, but you can't use this site to promote your own business.

Just a quick update on the subject of ~cheap~ (i.e. sub £4) LED downlighters:

Just received a 60 LED SMD-type downlighter and tested it next to the 3*3W type.

If you are using ceiling downlighters, the 60 LED type are next to useless, because they don't produce a spot of any sort. The lensed 3*3W on the other hand do, though the spot area is smaller than a corresponding halogen (the makers quote a beam angle of 45 degrees, but the ones I have are probably only half that width).

IMO the only situation where the 60/80 LED type are likely to be any use is where the area to be illuminated is close to the lamp.

Just some info for those interested.

Firstly OP. If your lamps are blowing quickly then I'd bet my birthday money that you are using the wrong lamps (bulbs). Unless the back of the fitting is open to something like a loft, you should only use aluminium lamps NOT dichroic. Dichroic lamps were developed for the fashion industry and throw the majority of their heat out the back. In an enclosed space this means the lamps overheat and that severely shortens their life. Fitting an aluminium lamp will throw most of the heat forward. You can tell the difference tween them quite easily. The dichroic you can sort of see through and the aluminum you cannot.

LEDs. On a cost/life/output basis compact floris are far better performers. The latest ones are instant start and light outputs are comparable with halogens. Further they last and cost next to nowt. One might suggest that LED MR16s and GU10s are for posers who like teh dark with money to burn... :rotfl:

My understanding is that it is the light output or lumens you need to look for along with the colour. A 50w GU 10 puts out around 400 lumens, so you need a replacement that out puts in the 350+ lumen range. Then what colour the warm colour associated with halogen GU10 is between 2500 and 3000, but you may want it whiter or very warm.
LEDS do not perform well in a confined space where they can get hot so they need cooling fins to give out the kind of light on a 50 w bulb.
There is a lot to take in and it would seem you get what you pay for. Sylvania an Toshiba provide some of the best branded lights in the 6.5 - 7.5 watt LEd GU10s giving out 350 lumens or more. I beleive Sylvania invented the GU 10 format.

I bought some of these:

Then I bought some more of them, and then I bought some more of them, and then I told all my friends to buy them, and now I'm telling you to buy them. I've been using my original batch for ~ a year now, no problems yet. Good brightness, good colour, although it does have a slightly different feel to it. I just put another 4 in our new bathroom. I have no complaints and am planning on buying another 12 for our new kitchen that's currently going in.

I bought 10 from www.simplyled.co.uk not the cheapest but produce 430 lumens of light output and they are brighter then a normal gu10 halogen bulb with a 120 degree beam

50w halogens give out far more than 400 lumens. I replaced 50w halogens with 380 lumen LEDs. They were both warm white, and 60 degree beam angle (you MUST check the beam angle!). I'm looking for 400+ lumens MR16 bulbs now.
They're getting brighter and cheaper all the time...

The cheaper ones will give out about 400. The more expensive can give out 600+
