One important feature that may be required for your installation is how it handles power outages. Some controllers have the ability to restore lights to their previous state when he power is returned.
The majority of LED light strips use a 12V dc power supply but this can be a limiting factor. Each LED strip inherently has resistance so as you move a long it, the voltage seen by each LED has dropped slightly. With higher power, higher brightness LED strips, this can become significant and visible. This effectively limits the length of LED strip that cna be used.
One way to overcome this issue is to 'inject' power at regular intervals (e.g. every 5 meters), using higher current wiring. Whilst this is just 2 wires for a single colour strip, it becomes 4 wires for an RGB strip and 5 ofr and RGBW/WW strip.
One way to mitigate against these problems is to use 24V dc LED strips. This means that the same light output can be achieved using half the current and thus half the voltage drop along its length.
