The Parabolic Reflector DLP allows Dual Lamp Positioning in either a horizontal or vertical burning position. With the lamp positioned horizontally the reflector will provide better light penetration with a wide angle coverage. With the lamp positioned vertically, the reflector will provide a more uniform spread of light with virtually no hot spots meaning that less heat is directed into the plant canopy. This is a popular configuration for use in grow tents. The large size of the reflector provides a really wide angle of coverage even at the lowest mounting heights making it ideal for use in areas with restricted head room.
