HI! I've used about 160 ft of VOLT® Dry Use - White - Standard Output, LED Strip Lights to illuminate a lot of built-in book shelves I've installed in a new library room in my house. I'm having trouble finding a PWM dimmer for the installation, since I have so many feet of lights, most of the dimmers are rated at too low a wattage. Does anyone know of a higher-wattage rated (wall mount) dimmer? Thanks! I should add that the 160 ft of LED strip takes about 1.45 Watts/ft (per VOLT) so I believe I'm looking for a dimmer that can handle 240 Watts.
