I know this has been discussed some but here is the situation. Installed a pergola about 2 yrs ago with Stellars. They wanted this lighting switchable so we installed a toggler and the system has worked flawless. This is a signle run out of 7 runs in a 900w MDL transformer. Now the client would like to be able to dim that one run but doesnt want to fork out for the ABT or a seperate trans. There is already a single gang with flip cover in a mortise on the pergola post we installed. Does anyone know of a GOOD 12v dimmer rated at about at LEAST 10-15a we can swap in place of the toggler ?
