At first, I had doubts about its performance, (8675lm/75w & 7370lm/67w according to the manufacturer, with dimensions of 60X60 & 40X40 cm respectively). I dared and bought one 67w and one 75w and I didn't regret it! The light intensity is more than enough, even from the 67w model. Fortunately, it can be reduced with the remote control. The light temperature is also adjustable. The settings are made in small steps and very easily, so one definitely achieves the desired light. The absence of "flickering" is also impressive, especially if the space was previously illuminated by a different type of lighting (not LED), which makes this light ideal for workspaces. One would think that the space is lit by sunlight! This particular light can be hung or directly screwed into the ceiling, there are no 2 versions "S" or "P" as mistakenly described by the stores. The only drawback I consider is the fact that the settings are maintained only if it turns on and off from the remote control and not from the main switch. An excellent purchase, which I highly recommend!
