Why use 12v downlights

[Bul]

Do many of you choose to install 12v downlights instead of mains ones?
I was thinking that doing away with the problem of the transformers failing. I still see reasonably new installations with 12v downlights.

As an apprentice we always fitted 12v due the the brighter, whiter, light output.

These days I only fit high quality led fittings

Any augment for using MR16 low voltage downlighters instead of the latest 230v led GU10's, has now gone.
I'm thinking the only reason is that they can still buy end of line really cheap MR16 stuff because making profit is more important than giving their customers the most appropriate and up to date lighting solution.

Can't think the last time I fitted 12v lighting .......

There could be another reason they still use MR16's instead of GU10 led 's - poor product knowledge?

I recently replaced some of your 'bright, crisp white' 12v halogens:

I changed them for Philips GU10 LEDs:

I know which one I think looks better.

I've recently installed loads of it....but it was a tension wire system.

Or just dodgers and builders going to sheds?

The second pic there is a light on to the left and at the end which aren't on in the 1st pic.

wtf? 12v mr16 is brighter and a better quality of light than gu10 halogen. It's only the new LED fittings that have bettered them.

Your pictures are not comparable due to the other light sources present in the second picture. Retake the pictures without the additional lighting and using a camera which does not automatically adjust it's settings.

You have to compare like with like. 12V halogen is generally better than 230V halogen - the lamps are more efficient, more durable and have higher colour temp. So then you ask 'Why install halogen.' For critical applications that need the best colour rendering, you can't beat it because it's a proper continuous light spectrum similar to natural light. So for example I use halogen over my main work area and bench instead of LED, and therefore 12V. In a corridor, 230V LED is ideal.

Edit: Davesparks beat me to it while my internet was going wibble

I agree with the post about that second picture, you can see the tight cone that the LED is giving but there's some supplementary light there that isn't on the first one.

the only place most of us will run into mr16 on newish houses will be the rubbish combined spot/extractior fans.

the bathroom in this new house has a really bad damp problem because it just doesnt extract enough.

no window either lol

A lot of commercial lighting is specified as MR16 12V because of the colour rendering. It's also feasible it might be a better option as ELV in certain higher risk zones like above a shower for example.

You better get a stock in of those halogens, cos the EU's gonna get rid of them in 2018; EU delays ban on halogen bulbs | EurActiv, unless we are not in the EU by then :rolleyes4:
