Stack's sensor-enabled smart bulbs left us impressedAt $99, the two-bulb Stack LED Downlight Starter Kit is more affordable than Lifx or Philips Hue -- and arguably smarter than either one.
[MUSIC] Today I wanna show you some of the smartest smart lights that I've tested in a while. They're not Philips Hue bulbs and they're not LIFX bulbs, either, they're the stack LED downlights. Now, I've got the starter kit here. It comes with two flood lights and the hub that controls them for $99. The bulbs are really interesting, because they change color temporarily. Which are tunable. So if you wanted a nice hot white light in the morning, and then a relaxing yellowy light at night, you can set them to do that automatically. You can also schedule them to come on in the morning to wake you up or change color temperatures during the day based on a schedule. A lot the basic features you might expect from a smart lighting kit. What's really interesting about these bulbs is that they also have sensors in inside of them. Sensors both for presence and for ambient light. So there is a lot of sunlight coming in through the windows during the day, they can automatically dim down to help save energy. As it sees you walking into the room it can turn on automatically. These bulbs also sync up with the Nest learning thermostat. In the stack app You can set your rooms based on how warm or cold they are. So they're a little warmer than the average temperature in the house, a little cooler, you can tell the app that. And then when the bulbs know that you're in those rooms nest that and the nest can heat a little more aggressively or cool more aggressively based on what you want The bulbs also work with If so if you wanted to craft a custom If recipe then it works with Alexa, like Alexa trigger movie mode and the lights dim down. You can do that too. The Stack bulbs tested well in our lighting lab. They also have a very comprehensive app that has a ton of settings. If you wanna get really specific with how they work, you can do that. And at 45 bucks a bulb or $99 for the two bulb starter kit, they're less expensive than Phillips Hue and [UNKNOWN], bulbs that don't have extra sensors in them. I think that's a pretty good deal, and that makes these one of my favorite new bulbs to hit the market. [SOUND]
