Revogi LTB012 LTW012 Smart LED Light Bulb, 62Mm x 62Mm x 110Mm, Silver/White

I purchased 3 of these bulbs in one order from Amazon. I previously purchased 2 of these from BHPhotovideo. The two from BHPhotovideo worked fine. Two out of the 3 bulbs from Amazon have required replacements. Amazon is working with me to replace these bulbs, and as soon as I have three working bulbs I will edit this review. When these bulbs work properly they are awesome, but with one of them it would not turn on at all after a day of use. The other one would randomly turn off and on, and I could not maintain a bluetooth connection to it. I have a total of 7 of these bulbs, the first two I bought are the first version, and they both worked great without replacements. They all connect with the delight app, most of the time. At times I may have to delete them from the list, and make the app search for the bulbs again, sometimes it will require turning the bulb off and back on. I believe this is just a limitation of bluetooth, and may possibly occur more often with more bulbs in the same house.As I mentioned, when I am no longer having issues with these bulbs, I will update this review, and probably give it at least 4 out of 5 stars.

I have 8 of these bulbs. I loved them when they were working. I got one dead on arrival and the replacement failed immediately. The rest are two years old and work great. I contacted Revogi customer support and they sent me a link to an account for my issues. The link is in Chinese! So no help.

Have trouble getting the color set at desired setting when using the schedule function. It defaults to a very "blue" setting. Online help couldn't advise on a fix. I think it's a design flaw that should be corrected.

It was a gift and so far no complaints and it has not burnt out.

The range is only 5 inches

It is now only a dimmable led bulb that can be turned of and on with the App.
