Popular streamer key lights cost $100–200 for what is, physically, a bright panel of adjustable white light. A spare monitor is a bright panel of adjustable white light. CineGlow gives it the controls: Kelvin color temperature, brightness, and presets that match studio conventions.

Practical placement for a desk stream: main monitor for gameplay, second screen at 45 degrees as your key, and a phone or tablet behind you on a warm preset for background separation.
