Woot is having a day-long sale on a range of tech, including a mix of new and open-box Philips Hue smart lighting. The retailer’s already-discounted prices are even cheaper today when you enter the code SAVETWENTY at checkout through midnight Central Time. The products included in the sale serve as a great introduction to setting up smart lights, or diving a little deeper.

For starters, there’s the Philips Hue Bridge Gen 2 that’s $25.60 with the code (versus $65.99 new at most), which is a required gadget for operating some Philips Hue products. For instance, you’ll need it to setup the Play HDMI Sync Box 8K ($212 with code, originally $384.99) that can sync other Hue lights to what’s showing on your TV screen. While some Hue devices fall back on Bluetooth, you’ll eventually need a Bridge if you plan to setup more than 10 lights or if you want to control lights remotely.
