The Robolights Chameleon Colour Scroller was designed by Julian Baycock specifically as a compact unit with a 150 mm aperture for use with 'sub-kilowatt' lanterns. It's development bought colour changing into schools and amateur environments which usually made use of 500 / 650W lanterns. The Chameleon used the same analogue control signal so it interfaced with simple analogue lighting desks without additional control equipment.
