Scout Alarm review: This DIY security system lacks polish
Our evaluation experience left us unimpressed and somewhat skeptical.
The Lightify Smart Sensor is a good add-on for Sylvania smart bulbs, but the Hue sensor demonstrates why Philips leads the market.

It’s cheaper than the only competing color Wi-Fi bulb, but it’s not better.

This bulb claims to be the brightest Bluetooth bulb on the market, but its light is cooler than expected.

You’ll find lots of form factors in the Ledvance Lightify collection, but getting the most out of them takes some effort.

This year’s model is smaller, lighter, and brighter than the original, but scheduling within its app remains a weak spot.
