Having installed some LV halogen lights in the bathroom, I need to protect them against overheating or causing a fire by buring them under 250mm of Rockwool.
I know this has been covered before here, and solutions of large inverted plant pots (don't have any) or proprietary incandescent shields (expensive) have been suggested.
I think I've come up with an alternative solution; that is, to use offcuts of 4" soil pipe or ducting as 'chimneys' to surround the fitting neatly and duct the hot air upwards (would also illuminate the roof space quite nicely! Don't have any spare of either unfortunately so was going to order up some Screwfix ducting (ref 15872 - five 350mm lengths for 5.95GBP).
So - do we think this would be OK? Or might it melt if it was that close to the fitting (50W bulb)?
Thanks David
