The Robolights Colour Scroller followed on from the development of the earlier Robocan and used similar technologies. Designed by Julian Baycock The MK1 versions accomodated 11 colours made as a continuous strip, which loosely reflected levels 1 through 10 on an alanlogue lighting desk. These Scrollers were designed to fit Parcans and other 1kW lanterns of the late 80's era. Control was analogue, using the 0 to minus 10V control voltage that was widely used at the time enableing the scrollers to be controlled by a simple analogue lighting desk. Debut for the Robolights colour scroller was at the Northcott Theatre Exeter.
