Can CAST fixtures and transformers be dimmed?
Properly designed landscape lighting systems use low levels of illumination positioned and aimed for optimal effect. Dimming these systems typically deteriorates the lighting design and serves no useful purpose. Still, if dimming control is required there are several factors to consider: • The best approach is to use a dimming system that reduces the voltage at the secondary transformer circuits (12v to 22v). This bypasses any potential problems with compatability with the transformer’s magnetic and electronic components. • All tungsten/halogen lamps should not be operated for extended periods at less than 10V. These lower voltages will cause the bulb to blacken and reduce the lamp life. • All our transformers 900w and greater have electronic components that require a minimum of 100 volts to function normally. Dimming below this level will cause the transformer to malfunction. • Only our CJ300 and CJ600 series can be effectively dimmed to lower voltages (less than 100V) with a magnetic
