Halers H2 Pro 550 60D LED Downlight Chrome 2700K White [Energy Class A+]

Very good quality and still the best available to date.Expensive, but quality costs money.

We have a similar model LED downlight in our house (60 WW instead of 60D, which probably stands for Warm White). Be aware that these may be easy to install, but as far as we have been able to figure out the springs make them impossible to extract for replacement without pulling the ceiling down, except for what we eventually did, which was sawing through one of the springs with a hacksaw. The only advice the manufacturer was able to offer was 'get an electrician to do the job if you have problems'!Update: Collingwood have just emailed me a video showing their technique for the removal process, which I hope they will put on line. I'm not sure how well it would have worked with our LED as their spring has a bend in it which would have reduced the strain on the ceiling, but in view of this I've upped my rating from 1 star to 3.
