Which of the following is NOT a feature of smart lighting technology?

Smart lighting technology is designed to enhance user convenience and energy efficiency by offering advanced features that go beyond traditional lighting solutions. One of the key characteristics of smart lighting is its ability to be controlled remotely. This enables users to adjust their lighting settings from anywhere, typically through a smartphone application or other internet-enabled devices.

Another important feature is the automation of lighting systems, allowing for pre-set schedules or conditions to automatically turn lights on or off, or to adjust brightness based on the time of day or occupancy. This enhances energy savings and user comfort by ensuring that lights are only used when necessary.

Integration with home automation systems is also a hallmark of smart lighting technology. This means that smart lights can work in conjunction with other smart home devices, such as smart thermostats or security systems, to create a cohesive and responsive living environment.

In contrast, the option indicating "manual operation only" does not align with the core principles of smart lighting technology. Smart lighting inherently includes advanced control options rather than relying solely on manual switches or dimmers. Therefore, this choice is not a feature of smart lighting, making it the correct answer in identifying what does not belong to the set of features associated with this technology.
