If you don’t want to lay out the cash for a Philips Hue setup, this OxyLED bulb is a great semi-smart alternative for a fraction of the price. Each bulb comes with a self-charging remote (pressing the buttons actually generates electricity, how cool is that?) that can power the bulb on or off, dim it, or even swap between three available color temperatures.
The biggest drawback here is that you can’t program the remote to control multiple lights; you’re going to have a separate remote for each lamp. If that would work for your situation though, $12 is a great price.
