R853 Large 32 Watt LED Downlight
The R853 has a white rim and is 165mm in diameter and 137mm high. It requires a 150mm cut out. The light uses 33.3 Watts of power to produce 3065 Lumens into the shop. A 75 Watt MH will produce 5000 Lumen but some of this is lost in the light fitting.
This light is not dimmable
