Great bulb, as bright as it should be on white settings but very weak on color settings. I bought 5 dimmable white bulbs but wanted to try the colored one. I will most likely run out of color as it's pretty pointless, but it applies to late night hours with red or blue light depending on what I'm doing as it's bright enough to see but not bright enough to yours Eyes hurting They really don't need the color get their other white dimmable bulb they are amazing. Works very intuitively with Alexa. Installation was a bit of a hassle as for some reason they changed their app and they forced you to configure it manually via AP mode (you need to connect to it and then after a series of on and connect it to your router off (e.g. 7 times to enter setup mode) instead of just using their EZ mode.
