I would do as Smiley Dan says and switch to GU10's.

MR16's are overcomplicated and pointless these days.

Our new build has GU10's in the kitchens and in the bathrooms, and building regs were fine with it.

Is it easy to change from MR16 to GU10?

Not sure about easy.

It would depend on your setup. If you have transformers for each fitting, then you just take the fitting out and swap it for a GU10 of the same size and wire it to the mains connection. If they are connected by low voltage cable to a central transformer it becomes more difficult as a complete re-wire would be needed.

If your transformers are not suitable for LED then you would need a complete re-wire anyway, and GU10's would be cheaper to install from scratch as no transformers are required.

If you are serious about it you should probably get an electrician to take a look at it for you.

Can recommend these GU10s to replace 50W Halogens. I have never seen our kitchen in such bright light. Excellent delivery with printed invoice from German manufacturer (Sebson).

£35 for ten?

That's only £3.50 each! (I know you can all work it out but I thought it was worth stating!)

I wouldn't personally pay so little per lamp, but I wish you good luck with them.

I bought these which I'll admit are expensive, especially compared with the ones above.

I see most LED companies and manufacturers are still completely ignoring Colour Rendering (CRI). Crazy that some don't even publish the CRI outputs.

While I see the importance of CRI figures and there is no 'real' reason not to publish them, most home users (which is the largest chunk of the target market for these bulbs) are simply not interested.

If you are a photographer or cinematographer the CRI might be a big deal, but for Mable in her kitchen (no sexism intended) it isn't a big deal. I cannot see the CRI being so poor that you can't tell between a green and red pepper.

That being said, it is commendable that your company does make an effort to publish these details.

Changed these over myself this weekend. Was just a case of pulling the fitting out, unscrewing the old halogen and transformer and replacing with GU10 mains lead.

GU10 mains lead http://www.energylightbulbs.co.uk/products/gu10-mains-lead-240v-connector = £1.10

Integral LED http://www.amazon.co.uk/dp/B00MA7Y03O/ref=pe_385721_37986871_TE_item = £4.74

Total cost to replace 13 = £75.92 (£5.84 each)

The Integral LED's used are a which best buy, so confident on the quality, and LOT less than the high prices mentioned above. (£240!!!)

I changed my 10x50watts GU10's in the kitchen with 10x4w Warm White from LEDhut - cost about £60 about three years ago.

Savings = 460watts per hour = about 5-6p an hour. As we have them on for an average of 2+ hours a day we save about £40 a year.
The light is much better than halogens and there is less shadowing as they've got a much wider beam angle. They also last a lot longer.

I haven't bothered with the bathroom as we have 5 x 35w halogens = 175w. We'd save about 155watts = 2p an hour but as we only have them on for less than an hour a day we'd only saving about £7 a year it would take a lot longer to pay back.

I have just blown a 12v 20w halogen G4 Capsule cooker hood bulb. It's the standard 31mm length including pin. Looking to replace with LED, a straight swap would be ideal, don't wish to blow cooker hood or want a transformer, sounds too complicated.

We use cooker hood for ambient light, so its on a fair bit, also when cooking

Have contacted Baumatic (manufacturer), but still waiting. Has anybody swapped over with success.

Thanks in advance.
