Today only, B&H Photo Video offers the TP-Link WiFi Color-Changing Smart LED Light Bulb 2-Pack for $44.99 with free shipping. That's tied with our mention from two weeks ago, $22.50 per bulb, and the lowest price we've ever seen. (It's also the best we could find for this quantity by $51.)

These dimmable bulbs don't require a hub to operate, and each features remote control via the Kasa mobile app, a 25,000-hour lifespan, and compatibility with Amazon Alexa and Google Assistant.
