Elgato Key Light vs Key Light Mini – Which Should You Buy?

The Key Light delivers 2800 lumens and requires AC power; the Mini delivers 1400 lumens and is USB-powered. The Key Light is larger and brighter—better for full streaming setups and larger rooms. The Mini is compact and fits on any desk—ideal for video calls and minimal setups. Both use the same diffusion and color technology; the Mini is essentially half the output in half the size.

If you have a dedicated streaming setup or a large room, yes. The extra brightness gives you more flexibility—you can dial it down or position it farther away. For a typical desk video call setup, the Mini is sufficient. If you're streaming with a green screen or need to light a larger area, the full Key Light is worth it. For most users, the Mini offers the best value.

Yes. Both lights integrate with the Elgato Control Center app for brightness and color temperature control. They also work with Stream Deck for scene-based lighting. The setup is identical—connect the light to your network (Key Light via Ethernet or WiFi, Mini via USB to a compatible device). The app experience is the same for both.

Yes. Many streamers use the Key Light as the main key and the Mini as a fill light on the opposite side. The Mini's lower output makes it ideal for fill—you don't want fill as bright as the key. The combination works well for a two-light setup. Both can be controlled together in Elgato Control Center.
