Govee App and Music-Controlled Strip Light | $20 | Amazon | Promo code 5TBDOFTR
$20 would be a good price for a barebones HDTV bias light that you have to get up off the couch to control. But today, that gets you a 16.4' strip with a built-in microphone to bounce along with ambient music, and even Wi-Fi app and Alexa control. I have a similar set from the same company behind my TV, and it works great. Just use promo code 5TBDOFTR at checkout to get the deal.
