I recently purchased some downlights on ebay that arrived without installation instructions. I have sorted the wiring out but (and I know that this sounds daft)I can't figure out how to keep the bulb up in the recess. The kit come with an outer housing, two springs and a circular piece of wire that I think attaches to the springs in some way, shape or form (????). The bulb fits directly into a transformer and will quite happily hang loose but when the housing is put into the ceiling it just falls out. Am I missing a piece of kit or do I just cable clip the excess cable? Any advice gratefully received.
