The whole Philips Hue Outdoor portfolio has been created as one system, meaning all parts work together. In that sense both versions (2 and 5 meter) of the Lightstrip Outdoor fit and can be used as extensions to the other Philips Hue Outdoor (color) products (i.e. Calla, Lily). Do keep in mind the maximum W of the PSU available – 40W. When used in conjunction with the 5 meters / 197 inch Lightstrip Outdoor, you cannot extend with other products otherwise the PSU will shut off and reset itself causing the lights to flicker.
