LEXI Lights have a range of 60 ft with line of sight (i.e. no obstacles).
Their range is reduced by things like walls to approximately 20 ft. However, Lexi uses a mesh network, so the more lights that you have in the network, the more reliable it becomes.
You should place LEXI lights within 20 ft of one another. Some types of walls may require a shorter range. You can extend the range throughout the house by staging the lights ~20 ft from one another in a step wise fashion.
