When used with a fan, air cooled hydroponic lighting allows plants to grow nearer to the lights and is therefore more efficient. A two way spigot allows two air cooled lights to be connected to one extraction fan. A two way spigot is pictured with an integral adaptor to reduce the diameter of the outlet hole. Two small (75mm diameter) inlets join to a main can, which has one 100mm diameter outlet, intended to be connected to a fan and possibly on to a filter.

Note that air cooled lighting reflectors can be purchased before purchasing spigots, ducting, fans and filters. This allows a lighting system to be upgraded as budget and experience permit.
