Bathroom Mains Downlights

[pfenwick]

Does anyone know where I can get some mains downlights for zone 1 in a bathroom?

you'll find zone 1 will be supplied by 12v transformers and IP rated 65

Doesn't have to be, if the manufacturer says it's OK for Zone 1.

Which is good, because it means that pfenwick won't have to install those useless 2" dia spotlights, and can use something larger which actually works.

However - pfenwick - what's above the bathroom?

If it's a loft, are you aware of the work involved in sealing the lights and maintaining insulation cover, and if it's a flat roof are you aware that it'll probably be impossible to install any recessed lighting in a legal way?

Not true.

Eterna manufacture an IP65 240v GU10 recessed downlight.

Yes, but if you don't have to stick to ELV, and therefore can have a much wider choice, why would you deliberately choose to install something which isn't meant to do what you want, was never designed to do what you want, and will be useless at doing what you want?

Mood lighting ?

I have four of the above 240v GU10 downlighters in my en-suite complete with 11w megaman low energy lamps.

They look good, do what I intended them to do, are installed in a room they were designed to be installed in and light my en-suite very effectively.

And how well lit would the room be with 44W of fluorescent lighting using luminaires designed to provide room illumination?

A tad brighter, maybe?

 

[GaryMo]

That I don't doubt but that's not to say that the product I chose doesn't work and is most definitely fit for purpose whilst providing a more than acceptable level of room illumination.

Aesthetics must also come into mind when selecting a luminaire, not just functionality though the fitting I linked to above scores highly in both departments for my chosen scenerio.

ban, i cant believe you're even knocking CFL downlights now. I thought you agreed, they are a good compromise for your hatred for downlights.

You know you're in a credit crunch when the actors come here for advice on DIY...

The type of lamp is irrelevant - I'd knock LED ones too.

What is wrong about them is not their absolute power consumption, it is that they are not designed to provide general room illumination, so they will always be less efficient than luminaires which are designed for that purpose, and designed to properly exploit the light source used.

So GU10s using incandescent lamps will always be less efficient than proper room lighting using incandescent lamps.

GU10s using CFL will always be less efficient than proper room lighting using CFLs.

And so on.

Plus CFL or not you still have all the problems associated with perforating the ceiling, and you still have a lighting system which simply does not work properly.
