Vesuvio OS CYM 250 shares the same benefits as the standard model, but with a different optical system producing a much narrower beam of approximately 17° to light less area but with greater reach suitable for example for taller buildings or to highlight smaller areas.An expansion filter can be added for an alternative 68°x 23° beam angle . As with the standard unit, colour sequences can be selected from a pre-programmed internal controller, with multiple unit synchronisation possible, or controlled from the IP65 CYM dedicated controller or from any DMX512 control system
