Question: Does this bulb have a dawn simulation feature? That is, slowly brightening over 15 or 20 minutes to simulate dawn.
Document: This is the best plug and play bulb on the market. I had it up an running in minutes. The bulb can be easily controlled with any apple device. You can tell it to flash when your phone rings. it will flash to the beat of the music. It will come on slowly to wake you up in the morning. The disco party mode is pretty cool as it flashed like a strobe light in any colour.
Even if the light didn't have a switch, I could access and unscrew a lightbulb in less time than it takes me to turn the light off via the app.The biggest disappoint for me has been the wake-up feature - because it doesn't work. The interface here, again, is awful - but you can find your way around it to set the time you'd like the light to turn on as well as choose wether you want it to take 5 or 10 minutes to turn on.
I have a IR remote controlled 7 Watt LED color bulb which outputs the same brightness, in the same pattern, with strobe and other options, with 16 million colors for which I paid $15.00 on Amazon. It appears customers are paying a premium for app development, Apple device compatiblity, bluetooth implementation, and some additional features.The app was spotty in use. From 20 feet away, the bulb often would not connect or would take several seconds to connect.
I was able to connect this LED smart bulb to my iPhone using the simple instructions and was able to control the light color in minutes. It is fun to use and very customizable with many different color options for different room mood.
I starts with a burst of relatively dim light, then proceeds through a series of noticable steps of increased brightness, kind of like you were clicking through a brightness dial with positive steps rather than slowly sliding a dimmer.This is OK as a fun novelty. If you have $50 for a multi colorable light bulb and that's what you want, then go for it. Fun party thingy, but that's about it.
It's a fun party trick and for guests, but we had to move it from the living room, because we needed more light.The app has a feature for using the bulb as an alarm clock and I tried that, but I hated getting up with the light because it wasn't effective for me.It's a fun product and now use it in my office lamps. If you are in the market for this product, this is a good one that functions well and the app works great on my iPhone 5.
I really like this Lumen LED smart bulb. I set it up in a bedroom and downloaded the app to my iPhone 5s and within minutes I had the bulb changing colors as smoothly as a chameleon. The bulb works via blue tooth and seemed to react to my phone from a normal sitting position 5 feet away.
So why doesn't it work? I don't know. I've tried to use the bulb as my alarm clock for the past week or so and I think it's automatically turned itself on once - and that time it still didn't actually turn on until about 40 minutes after I had it set.After receiving the bulb and playing with it, I thought it was neat, a novelty - but it also became apparent that this isn't even in the same market as the Philips Hue and its competitors.
I bought this bulb primarily for the wake-up light feature. When compared to the Philips Wakeup Light and similar product, it looked like the lumen would be a cheaper option with a bunch of more useful features, but the disappointing fact of the matter is that this bulb completely falls flat as a 'smart' lightbulb.Does it produce light? Yes. Can you make the light change color? Sometimes. Does the bulb turn on automatically at a time you can specify?
The Lumen Bulb works just as promised and my kids love the music and strobe features. It even has a cool feature that when I leave the room the light turns itself off! I was looking at other options but for the money this seems like the best deal.The App is cool and they keep upgrading it and adding features. I can't wait to see what they come up with next. I will be adding more to light up my theatre room and create custom scenes for watching movies and gaming.
