House Light switch (ceiling fluorescents) is in the back next to the schedule monitor
Wifi-enabled Lights
The studio is equipped with 4 lights that are wifi-enabled (Govee lights):
Lightstrip behind TV
Floor lamp near TV
2 desk lamps
Floor lamp behind desk in corner
You really won't be seeing the effect of these lamps unless you were at the studio after sunset or blackout shades were used.
They're currently grouped together so when you say "Alexa, turn on [off] all lights in Studio", they will all turn on [off].
You can download the Govee app (iOS/Google Play) if you're inclined to change the colors.
