Works well - switchable colour temp and dims nicely. Unfortunately can be mounted backwards on rail too easily (and in that case it doesn't work). Took a while to figure this out. Mounted correct way it's a bit wobbly but doesn't matter too much because it's on the ceiling after all where you aren't going to bump it. So far so good.

Exactly as described. Lovely matt finish

I couldn't belief the value on this track head, similar styles are over double and was a bit skeptical but the performance is just as impressive. Smooth dimming and really bright. I choose the black version and it has come up as a real feature to room. I can't recommend this product enough, super happy customer :)
