We all know surround sound can enhance your home theater experience with immersive sound, but there are also devices out there that can increase visual immersion, such as the Govee TV Backlight 3 Lite, which adds dynamic LED backlighting to your setup.

If that sounds like something you'd like to try for yourself, the new Dune-themed version of the Govee TV Backlight 3 Lite is on sale for a limited at Amazon in celebration of Dune: Part Two, which just released in theaters this week. There are two models available, one for 55- to 65-inch TVs, and a larger version made for 75- to 85-inch TVs. Both models are $10 off when you select to coupon code on their Amazon store pages.

• Govee TV Backlight 3 Lite for 55"-65" TVs -- $80 ($90)
• Govee TV Backlight 3 Lite for 75"-85" TVs -- $100 ($110)

While there are multiple Govee devices that add backlight effects to your TV, the Govee TV Backlight 3 Lite features an enhanced processor and LEDs for better color accuracy and presentation. The device uses a strip of LED lights that attach to the back of your TV, and a small camera that balances at the top of the screen that scans what you're watching and dynamically adjusts the LED light colors to match.

The devices support all TVs that fit the size range, and the effect works with movies, games, YouTube videos, or anything else you watch on your TV. There are also pre-made lighting options, including a new Dune-themed orange hue exclusive to these models, and you can manually control the backlight with the Govee Home App or via Alexa and Google voice commands.

Govee TV Backlight 3 Lite can sync up to seven additional Govee light accessories to expand the effect to other parts of your room, such as the Govee Floor Lamp, which also has a limited-time coupon deal that drops the price to just $90 (normally $150).
