SYLVANIA SMART 10W BR30 LED Light Bulb for SmartThings and Alexa, Dimmable, 10 Year, 800 Lumens, 2700K, Soft White - 1 Pack (74581)

I've had these bulbs (2) only a short time but I'm very pleased with them so far - I will update later as necessary. I use these in recessed sockets over two chairs in a living room. For those using Samsung's SmartThings hub, a word of "relief" for any that have had frustration with the (poorly rated, 2.6) Sylvania 'Lightify' app - DON'T USE THE APP! Pair the bulb as you would any other SmartThings device and a controller application will show within the SmartThings app. It provides a full range of intensity, and all colors are controllable. Don't get caught in the 'loop' of trying to "create a Lightify account" as the instructions insist. The instructions are for pairing with the Sylvania Gateway device.The bulbs both paired easily with the (Samsung) hub - initiate the 'new device' and then turn on the power to the bulb(s). When 'found' you can name the device or leave the Sylvania nomenclature as it is. Creating scripts for the bulb is as easy as any other of the Samsung devices and done the same way e.g. on at sundown off at 11:15 p.m. The bulbs will resume at whatever setting of intensity and color that they were set when turned off.Not surprisingly, the range of color goes from the sublime to the ridiculous with the extremes of the color range being...well extreme. Not to complain though, the range of color is so broad that there will be something for everyone.A note from the SmartThings Support page: "Note: OSRAM LIGHTIFY bulbs have a known firmware issue that can occasionally cause them to fail as ZigBee repeaters. This can potentially cause other ZigBee devices to fail to update and/or respond." My opinion follows - this is a 'potential' issue only if you must depend on the bulbs as RF range extenders.___edit added 1/30/17___From the latest Samsung Smart Things Hub OTA update notice: "This update ... adds capability to provide over-the-air firmware updates to Osram and Hue bulbs." My Opinion follows - Samsung is adding a path for Sylvania to update its bulb firmware.

I have had a few bulbs for a few months. Setup connected to a SmartThings 2nd gen hub. The 2nd gen hub was a necessary upgrade from the 1st gen (kickstarter) hub, which lacked the signal range to reach all my lights. Once I replaced with the 2nd gen, the lights worked beautifully, as described. I am pleased with the programmable colors and routines. My whole house has automatic dayshift (4100k, 100%) and nightshift (2700k, 60%) lighting based on the sunrise/set!So why only one star? Longevity.In about 6 months, I've had 3 lights fail from 2 different vendors on Amazon. I had a 4th light arrive non-functioning. By "fail," I mean that they still receive signals from the hub and can effectively light up with some colors, but the normal white lights are gone. After it fails, when you try to set the light to a normal white light (with any kelvin setting), it shines with a dim, blue-green color. Completely useless as a light bulb.These are expensive light bulbs and the rate of failure I'm experiencing is both significant and rapid. They simply need a longer, more reliable lifespan for the cost to be worthwhile. I have normal (not smart) LEDs that are guaranteed for 10+ years. I'm not expecting 10 years from these, but, man, at least 12 months would surely be nice.To the seller's credit: they've been helpful and responsive while servicing what appears to be a defective product. I no longer trust Sylvania for any smart lighting. I wish it worked--it's awesome when it does.PS: each time you replace a bulb, you have to fully reprogram it -- a significant nuisance for bulbs that need to be frequently replaced.

EDIT (11/29/2018): It appears as if the Amazon Warehouse issue has been resolved with these bulbs, at least for now.I have also learned that if you are willing to mess around a little bit with setting up a special device handler for these bulbs in Smartthings, you can get a significantly improved range in the warmer levels for the white settings. The Osram/Sylvania RGBW bulbs (73693) are designed to go as warm as 1800K (candlelight), although for some reason the Smartthings standard setup stops at 2700K, and the Lightify hub currently stops at 2000K (although I have a distinct memory of it being able to get down to 1800K when I first got it in late 2017).END EDIT.I have ordered this product twice through Amazon Warehouse (two boxes each), and both times they were NOT the product advertised! Instead, they were the typical cheap, regular, NOT smart LED bulbs that you can buy at any old store for a few bucks each: Two 'Great Value' (Walmart) brand bulbs, three Philips (no, not Hue) bulbs and three random GE bulbs. That's what they sent me. Nice job, Warehouse inspectors.Also, the second order was described as 'like new' and in original packaging, none of which was the case. I mention this because there are currently (11/15/2018) three other boxes described exactly the same way on the Amazon Warehouse page; I would be deeply suspicious of them and their contents, if I were you.I am getting refunded for all this, but still ...That said, I do like the ACTUAL Sylvania RGBW bulbs. I currently have 19 of them scattered throughout the house (bought through Amazon and other sources), and the colors they provide are rich and bright, the white temperature range is excellent (particularly if you are lucky enough to get a Lightify gateway for them that actually works), and they seem pretty durable. I have had one of them go a bit wonky on me (it flickers manically if I set it above half brightness), but I did drop it, so there's that. The rest have worked fine for me, and I have had some of them for almost exactly a year now.They also work fine with the Smartthings hub, although the white range is more limited (2700K for a lower limit vs 2000K) than it is for its native Lightify hub. If you like really warm whites (candlelight), that might be an issue for you. But as I mentioned above, the Lightify hub is pretty much a crapshoot for functionality. I lucked out with mine, but I know people who have never gotten theirs to work at all.In other words, if 2700K is warm enough light for you, stick with the Smartthings or other hubs known to work with this light. Smartthings also has better developed controls for them (especially if you use WebCoRE) -- and I doubt Sylvania will be providing much if any support for the Lightify hub in the future, particularly as it was an Osram design in the first place.
