This light fitting feels well built with its hefty aluminium heat-sink. You can choose between three colour temperatures, and it works with Diginet MEDM dimmers. It is very bright at full power, and flicker free when dimmed. It comes pre-wired, ready to plug in to existing surface mount sockets. Its performance is far superior to the various compact fluorescent, and LED lights it is replacing due to its high light output and wide 120° spread. I am very happy with this purchase.
