Ledvance Lightify RGBW A19 review: Affordable smart lighting with a steep learning curve

Osram recently spun off its lamps division, branding it Ledvance. But little seems to have changed when it comes to the Lightify LED bulb product line, which has a diversity that looks a lot like it did last year. The one big twist: The company has added a full-color tunable bulb to its lineup to complement the white-only bulb we reviewed last year. Firmware updates have also taught older products a few new tricks. Ledvance Lightify bulbs are built to closely mimic standard incandescents in appearance, and they're designed to work with the Lightify Gateway. The gateway is a small ZigBee device that plugs into any wall socket near where you have the bulbs installed, easily bridging the gap between lighting and your smartphone.
