Conduit box LED dimmer 0-120w aged gold front. After the great success of my copper conduit LED dimmer I decided to make the same dimmer switch with an aged gold dimmer knob. Inside I have used the same Varilight 0-120 watt LED dimmer module. This is trailing edge and will dim up to 10 x LED lamps. The dimmer is fitted inside an industrial metal galvanised end box with a galvanised lid. This is ideal for urban and industrial lighting designs. It has a simple 20mm threaded entry and will fit on to any 20mm metal conduit.
