down lighters MDF??

[lancenotalot]

I want to make a centre section of the living room ceiling lower than the rest by about 75mm.
I was going to do this by fitting a timber frame through to the beams and then fitting some MDF onto the frame.
My question is will MDF be safe to fit down lighters into or will the heat create a problem?

I was looking at something like this

You need a fitting suitable for mounting directly onto a flammable material.

All suitable fittings will have a letter F inside an upside down triangle on them.

Like this one for example:

It is very difficult for MDF to burst into flame but it does count as a flammable surface.

You should look for F-marked fittings (designed for use on a normally flammable surfaces). The fitting with tell you what power lamp you can use it may be 35watts rather than the 50W you could use on a plasterboard surface.

AFAIK those cheapo B&Q ones aren't F-marked.

Edit: curses RF, don't you ever rest...

Why dont you use plasterboard instead?, mdf i would imagine would get very heavy.

thanks for the replies,will look for some with the F marked symbol,did think of using plasterboard but want curves on it and not sure how the edges would turn out.

With respect, it would seem that you do not understand what a fire-rated downlight is for nor the difference between a fire-rated fitting and an F-marked fitting.

in fairness I figured his point was that CFL's run cooler, which is a good point, I'm uncomfortable fitting halgen lighting to wood evan when it's supposedly F-rated

I certainally wouldn't use fire-rated fittings anyway, the enclosed space makes them run hotter, open back fittings and fire hoods for me...
