OSRAM LIGHTIFY A19 Smart Adjustable White LED, Dimmable, 9.5W, Hub Required

These Smart lights are ideal for app control from your Smartphone but also if you plan on using Amazon Alexa. I am using Samsung Smartthings for my main hub and these easily connect to the hub. After doing a few hours of research I decided to get these Sylvania Lightify bulbs to use in conjunction with my Smart home set up. I currently have 3 of these bulbs and all work great. I can use the Samsung Smartthings app or use Alexa to control these bulbs. I even have one of these for my outside porch in front of the house and have it go on when my Ring Video Doorbell motion detector is activated. If you need to control a lamp, hallway, closet then these are perfect. You don't need anything else to use these. If you plan on getting more than Smart light bulbs, like switches and locks and outlets the you need to invest in a hub. If you only are needing to control a few light bulbs then you don't need a hub. These will work without a hub.

A great product, comparable to Philips Hue tunable lamps, but without the lock-in to their hubs. Works natively with Wink, and I'm working on a Stringify program to have the color balance track with the daylight.Most importantly to me, the beam spread is nice. I've bought four of these and four of a competing brand's tunable bulbs, ones with a clear diffuser that look a bit more 'futuristic'. The latter are a bit more directional and work well in freestanding reading lamp fixtures, but the Sylvanias, with their more traditional bulb-shape and frosted diffusers put out a nice even beam spread and currently live in my glass-shade pendants.

When I first received these lights I was impressed. They were very easy to setup via the Alexa app using my Kindle Show as a hub. The warm-cool color range was nice and the lights were very responsive with very few missed events. However, about 10 days ago one of the lights developed a high pitched buzzing sound and started to flicker. It soon became unresponsive to on/off events as well. It was part of a group of five lights so I just unscrewed it thinking that it might just be an outlier. But within a few days all 5 lights in the group were exhibiting the same behavior: an electronic buzzing noise and rapid flickering and blinking on and off. The behavior has gotten so terrible that they are functionally useless.

This review is for the Tunable White A19 bulb. I'm using this bulb with a SmartThings hub. This bulb is not officially supported by ST yet, but I was able to pair it and write a deviceType that enables full on/off/dim/color temp adjustments. I've made that available on the SmartThings forum, but you will need to be comfortable with tinkering. The great community at ST can help you out though.The bulb itself is really impressive. It's compact with a nice diffuser very similar to TCP bulbs. The tunable white allows for a very warm "soft white" color (2700K) all the way to a bluish "daylight" (6500K) color temperature and it's working flawlessly for me. I prefer this bulb to the GE Link, but the price point is really high and the color temperature adjustment isn't worth the premium to me, which is why I knocked a star off.

Love these bulbs so far, I'm using them with SmartThings.I'd highly recommend joining the SmartThings community if that's what you're using. I didn't like how the bulbs first operated when I first got them, but after talking to some people on there, they provided me with custom code and a walk through on how to set it up, and now they work how I want them to.I wanted them to fade on and off, and to fade when you change the brightness, which I was able to accomplish via the SmartThings forum.As far as the bulbs go, it's too hard to review their usability because that all depends on which controller you go with (Lightify Hub, SmartThings, WEMO, etc). But the bulb feels of good quality, never have any problems with them randomly disconnecting, never have problems with flickering. They are VERY bright.I do however wish they could dim a little darker. Even at 1% they are still pretty bright in my opinion. I have a LIFX WIFI bulb and it's 1% is just barely enough to be a nightlight. However, that's a 60-70 dollar bulb. And that bulb has more cons than these simple white Zigbee bulbs.In the end, if you have the money, I highly recommend these bulbs for every one in your SmartHome.OH, also, one more thing, they DON'T retain their last setting when they lose power. So if you have them on a light switch, they will always default to 100% brightness and 2700K (yellow ish) light. It's best to always use them via the app/hub you choose. I personally use my Amazon Echo with them via SmartThings.

Only 3 Stars because while you CAN turn it on and off with WEMO, you CANNOT adjust color temperature. I will update once I hear back, but wanted to warn early adopters of issues you may face. I bought this after returning my TCP bulb which also is listed as being compatible on the Wemo site, and it simply not working. This Osram/Sylvania light is also listed on the site as being compatible directly on the WEMO site. It specifically says you can use the WEMO app to control the lamp and color temp. I tried this on an Ipad, Iphone, and Android phone with no luck on any of them to get the functionality described by WEMO.3/2/15 -- I raised a request with Belkin/Wemo and was told to contact Osram about the wemo app not adjusting color.

Ha impiegato un po' di tempo per arrivare dall'America ma alla fine il costo è più basso rispetto a quello italiano il prodotto è lo stesso e va bene

These bulbs are ok but I returned them as they were very slow when turning on. Took 10-30 seconds to come on. I find that Zigbee products are very unreliable and I had a lot of issues with reliability.

Excelente producto, funciona con mi smarthing hub y con el google mini...

The mesh networking feature just doesn't work - random bulbs lose connection from the hub at random. Super cool when they are functional, useless once the connection is lost...Not impressed.

Excelente funcionalidad , llego súper rápido además es compatible con diferentes gateway no solo el de OSRAM yo lo probé con el de VEras y funciona Ok
