Castor low-voltage spotlights are ideal for accent lighting or washlighting for shops and trade fair stands and also for exhibition lighting. The glare control for capsule lamps or reflector lamps is provided by a metal frame. The use of a dichroic filter means colour effects can be used. The brightness of most luminaires can be individually adjusted using the integral potentiometer. The DALI-compatible luminaires have digital control gear through which each luminaire can be individually addressed - for instance using the ERCO Light System DALI with its integral ERCO Light Studio software.
