I was at asda earlier. Don't usually go there but spotted unusual light fittings outside. Two types.
One had a thick white tube (maybe 1.5in dia) curved into a circle approx 200mm dia with metal clamps at the top and bottom of the circle.
The others looked the same tech but the tube was bent into a rectangle with the metal clamps at the short ends, the long ends looked about 400mm long.
The fittings themselves don't look dissimilar to high pressure sodium fittings (the round tubes were in bulkhead type fittings and the rectangular ones in floods)
What on earth are they?
