OSRAM LIGHTIFY A19 Smart Adjustable White LED, Dimmable, 9.5W, Hub Required (Pack of 2)

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.

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.

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.

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.

This light will drive you insane. It changes color e everytime it loses connectivity with the wifi. It turns on and off at random times. It sometimes will ho weeks no problem then bam trouble with it for a month. Drives .e insane

I bought five of these bulbs because I wanted to be able to set them for daylight light in the morning, and warm white light at night. I have a Samsung SmartThings hub, and the information on Amazon's web site (sort of) says they can pair with SmartThings. But when I got them, the Osram instructions say to download and install the Lightify App, then create a Lightify account. The problem is, using the Lightify App to create a Lightify account requires an Osram Lightify Gateway!But the Osram instructions are just plain out of date. If you go into Marketplace in your SmartThings App on your phone, select Light Bulbs, there's an Osram Lightify LED Tunable White 60W bulb under Osram Lighting, and you can easily pair the bulb with your hub. Once listed in Things on your My Home page in the SmartThings App, you have full dimming and color temperature control from your phone.Based on what I've seen on You-Tube, the Lightify App has a lot of functionality that you don't get by directly connecting the bulbs to your SmartThings network. But if basic dimming and color temperature control is all you need, setup is really simple, and doing without the Lightify Gateway means one less electronic device in your SmartThings network.

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...

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

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.
