The light output is excellent. The very slim profile is very appealing and makes the luminaire suitable for most ceiling mounted applications. Its double insulated feature makes it suitable for retrofitting in old installations that do not have an earth conductor. The idea of the mounting system is good but the installation proved rather fiddly: For the 500mm diameter luminaire he lanyard holding the luminaire is not sufficiently long to terminate the wiring and clip back the lanyard onto the base. It would be helpful to somehow indicate on the body of the luminaire the direction in which the body needs to rotate when removing the luminaire as hardly any user will keep the installation instructions for the design life of the luminaire.
