This bulb was easy enough to setup. It requires that you download the Solana app from your app store AND enable the Solana skill in your revain Alexa app. My bulbs did require the extra setup step where you have to flip the light switch a few times to force it to start blinking, but I've had to do this with even more expensive bulbs.The BR30 bulb in Frost is a white light that can be adjusted from a harsh cold blue to the warmest shade of yellow. From the Solana app, you can drag a slider to find your ideal color & brightness. From the Alexa app, you can adjust the brightness and then select 1 of 5 preset shades of white light. I am very happy with their 'Soft White', and find it to be a flattering color for the living room.These lights do flicker, which is a pretty big downside and why I am deducting 2 whole stars. I'm noticing about 1 to 2 flickers per hour. That doesn't sound like a big deal, but it is very noticeable and it's distracting. I've purchased several of these bulbs as I prefer the same bulb in a room, but I'm not sure if I will use these for additional rooms on account of the flickering.
