Plasterboard fixings for light fittings....

[Short Circuit]

I agree with i=p/u, if you are already worried about the weight of the light, it must be a fairly substantial one so the best solution is to fit a noggin behind it if possible and that spreads the weight out considerably. I use the Hollow Wall Anchors where possible for fixing anything to dry lining walls or ceillings. (like screwfix Quote No: 18266 ) but you really need the tool to use them properly. Also with any kind of fixings like this, where the hole is for the cables the actual plaster board is weakened so may not take that heavy light fitting!

You could also go for the circular dry lining boxes, if you make it a nice tight fit the lugs make it quite strong!

Depend's on the fitting. If it's just a pendant I'll use worm's and screws but if it's a heavy light I'll put a nogging inbetween the joist's and screw too that.

I've never had a problem with worm's, must just depend on the quality of them.

I'm very impressed with Fischer Universal plugs.

They are truly universal and only once in blue moon will I need anything stronger.

if its just a strip light or a small fitting, just use Rawl drywall plugs, screw them in 95% not the full way, they give a better grip that way, you could make up maybe 2 small thin rectangles of wood and counter drill holes, then screw them to the ceiling using Rawl Drywall fasteners and just use self tapping screws (the kind the drywall fitters use on the metal joists) as long as you wont screw through a twin and earth or anything on the other side...
