Lampsy's service was excellent.
The light is very good, although honestly overpriced for what it is. Some nice touches in the mounting hardware - in particular you don't have to take its weight while you screw thew up, but the hex screw used to clamp it tight is very awkward to use with the supplied standard length allan key unless you have very small hands. Also it doesn't any terminal for the earth wire, so you have to insulate that safely in some way to stop it touching the live temrinals.
Dims very smoothly on a standard dimmer.
