Not every light is supported — it depends on whether Home Assistant (ZHA) (or the underlying bridge) has a device handler for it. The list above is limited to lights confirmed to work with Home Assistant (ZHA).
You need a Zigbee coordinator (USB stick) connected to Home Assistant (ZHA). Once the coordinator is set up, you pair the light and it's controllable from Home Assistant (ZHA).
