I bought this expecting to have a usable red light for my room at night. Its super bright on "white" mode, but as soon as you put it on color mode, the brightness gets dimmed to around 20% of what it was. Its barely usable for reading or anything like that. I dont know why, because the hardware is clearly capable of bright light, but the software limits the colored light severely and makes this very impractical for night-time eyesight.
