Sleek design!, you can`t fault Philips for this shape?, bloody huge spigot mounts on them though! , I`ve been looking at ours whilst walking the dog, they all have some sort of spigot adaptors in them to get them to hold on to a standard 34mm outreach arm.
You can tell their designed to be a default post top mount.

It's definitely up there in the better led design lanterns. So far all the columns these have gone on fit without any problems, although makes me wonder if they have got different spigots?
