Smart MR16 LED Light Bulbs 5W, GU5.3 Bi-Pin Base, AC/DC 12V, Compatible with Alexa/Google Assistant, RGBCW Smart MR16 Bulb, WiFi Smart Spotlight Indoor Decoration, 3 Pack

I've been waiting on getting wifi bulbs for my monorail lights for a while. There are only a couple vendors that make this type of MR16 with the pin base and the reviews have been bad for them, and they are expensive. I saw these pop up, haven't seen them before, and since I had bulbs from this brand in candelabra form and they weren't expensive, I picked them up right away. Glad I did! Yes, the colors aren't as bright as I'd like, but the normal light output is great and I finally have that last layer of light in my space to make everything voice operated. Work great with Alexa and I'm happy with this purchase. Please keep making these!

Uses software for multiple "smart light" vendors. Look up "Smart Life" light app in app store. Complete garbage. I work in IT, have experience and worked with "imported" instructions, so I thought I could take a risk and order these lights. The instructions aren't bad, it's the actual hardware and software. Complete garbage, all of it. The lights work well as white "dumb" lights only. The software fails 90+% of the time even after a correct install. When working correctly, which doesn't happen often, the color is 25% the brightness of the white. Oh speaking of the software and working, it doesn't. For three nights in a row I had to re-pair the 3 of the 8 "smart" lights I purchased to get them working. Ok, so that sounds challenging. What about the other 5 "smart" lights? They didn't work for anything but white, and they were a different brightness from each other! It is so inconceivable as to seem purposefully scammish! "Smart Life" sells their "app" to any Asian factory wanting to market smart bulbs/sockets/dodads, so that they can churn out piss poor "smart" products and kill the market for real smart products that work. You can't find good products as they have poisoned the well. I will send these back and look for a non Asian brand that supports their product, but I wont hold my breath. Save yourself the heartburn and don't buy them in the first place.

[Edit]: Seller contacted me and replaced the bulbs, haven't been able to set them up completely with my instance of HA but they work beautifully with the Smart Life App!, they have a nice brightness and i think the colors have enough saturation.[Original Review]: bought them for my son's room, I needed 3 so I thought that this 4 pack would give me 1 spare. but out of the 4, only 1 lights up, the other 3 were DoA.The one that isn't dead works fine (which is more of a bummer as my son saw it and asked if we could leave only that one, but I cannot leave some smart bulbs and some that don't as that defeats the purpose.

The idea is great, you can create groups and change the whole group at one time. I had trouble with the bulbs malfunctioning during the night, turns out the photo cell that turned the transformer on would blink and cause the bulbs to go into the setup mode. I would like them to be brighter in the color mode.

Although the white setting was quite bright, I bought these for the colors red and green. Neither color was bright enough for my application outside at night.

Replacing another brand - that may have been worse, but these are just ok. At about a 25% failure rate - failure to pair, outright bulb failure, failure to configure - but they are returnable so will just keep doing that until I have all bulbs that work?But, the woman behind the UPS counter taking Amazon returns kinda annoys me - knocking down an extra star for having to deal with her.

Installed these in my apartment bedroom. They are great because they work as expected - I can control them in Google Home and use my iPhone to adjust their brightness/color/tone. I've never installed lights before and I used my step ladder and got it done. Great addition!

This is the 3rd company I've tried to buy smart MR16s from and no one makes anything of quality. These things are barely three months old and one is already dead. It just stays on, won't turn off. I turn it off in the app but it stays on, even though the app says it turned it off. It's broken.The first company that makes Matter-certified, high quality smart MR16s will win this product space. They don't even need to be RGBW, just single color but dimmable. Right now however, all I find is cheaply made lights that cost a lot but don't even last 1 year. I think it might be time to invest in a smart switch instead of smart MR16s.
