Changes to the Philips Hue Outdoor range
Philips have recently redesigned how to purchase the Outdoor hue range.
Previously when purchasing outdoor lights a base unit was needed and then you purchased extender units of the same kind allowing you to daisy chain up to 5 lights.
You can connect as many lights as you want as long as the amount of total watts used across all lights are below 100 watts. You can even mix and match different lights and still control them independently.
