Dimming controls are one of the best ways to change the mood of your space. Changing the way a room feels with lighting control is less inexpensive than changing the decor. Adjust a dimmer and voila new ambiance. When selecting a dimming control we need to match the control with the load type.
LOAD TYPES
Incandescent / Halogen: Line Voltage and Halogen lamps
Magnetic Low-voltage (MLV): Magnetic transformer supplied low-voltage
Electronic Low-voltage (ELV): Electronic transformer supplied low-votage
Neon / Cold Cathode: Magnetic transformer supplied voltage
Fluorescent: Electronic fluorescent dimming ballast
Light Emitting Diode (LED) Electronic LED driver
Before selecting any dimming control be sure to know what type of load you are trying to dim and the wattage of that load. The dimmer must be rated for the type of load and the quantity. As a general rule try not the mix load types.
