If a simple and cost effective solution is required to fill an entire room with dancing coloured beams, then the Kam Derby9 is what is required. Home to 9x3W RGBAWUV LEDs, the Derby9 is not short of power and creates sharp beams in mid-air with the use of haze or smoke. Incredibly for its price point, the Derby9 can be controlled via DMX which puts it way above others in its price bracket. It also has the usual auto, sound to light, master/slave modes as well as being able to be controlled from the supplied IR remote. An intuitive 4 button display on the rear makes navigating the in-built menus a breeze.
