    How many dimmable 50w downlights would you all recommend for a room of 17ft by 11ft? The ceilings are 8ft high.

    I think 9 (3 x 3) but have been advised that 6 ( 3 x 2) would be more than sufficient.


    Also, the ceiling is 12.5mm plasterboard with a skimmed finished so would 60 minute fire & acoustic rated lights be acceptable to the authorities?

    bog standard fittings would probably acceptable, depending on whether theres a flat or a garage above.

    Whatever number of lights you choose, if you're dimming them, splitting them into 2 or 3 switches will prove beneficial to your dimmers.

    It's on the top floor so above me is just a flat roof.

    The room is an open plan kitchen/ living room so I was going to split it into two areas for lighting; the kitchen with 3 lights and the living room with 6. Each area will have its own dimmer switch.

    You never know! :LOL: I was hypothetically speaking. Were there a garage above, the ceiling would have to be fire rated (IIRC), since all barriers between garages and living accomodation must be fire rated!

    it just looked like a fairly ordinary (metal box with buttons in it) but rather large lift though i didn't get a very good look at it.
