LIFX 17W BC Wi-Fi LED Intelligent Light Bulb, Multi

Product information

LIFX is a Wi-Fi enabled, multi-coloured, LED light bulb that you can control with your Apple or Android smartphones and tablets.

Set the Mood
LIFX uses a free app to customise your bulb, letting you remotely turn lights on and off, dim the brightness and change the colour, so you can set the mood whether you're waking up in the morning or entertaining a date in the evening. Bulbs can also be grouped together, so you can set the atmosphere in a whole room at once.

Energy Efficient with no compromises
This energy efficient bulb consumes between 0.2W and 17W, depending on brightness level and can last up to 40,000 hours, or 25 years based on 4 hours use a day.

It features a brightness level of over 1,000 lumens, which is similar to a 75 watt incandescent light bulb but 4 times more efficient at maximum brightness (17W).

Simple setup
LIFX works with existing wall switches and dimmers and can be installed by downloading the app, screwing in the light bulb and then choosing 'Add new bulbs' in the app and following the instructions. It doesn't require any additional hubs, control boxes or electricians. Depending on Wi-Fi signal strength, LIFX can support over 60 bulbs on one network.

Works with Nest
LIFX and Nest have teamed up to help you get the most out of your LIFX bulbs and Nest products. If Nest Protect detects smoke or CO, LIFX bulbs can flash red to let you know there might be danger and help signal those who are hearing impaired.
If you're going on holiday, LIFX and Nest can work together to make your home safer too. As soon as your Nest Thermostat switches itself into Away mode, LIFX can make it look as if someone’s home by automatically turning on and off your lights throughout the house, simulating your activity and discouraging potential intruders.

Please note: Wi-Fi features require an 802.11b/g/n compliant router in range of a bulb and either iOS 6.0+ or Android 4.0+ on your tablet or smartphone. LIFX bulbs are not intended for use in weather exposed areas.

Q & As

Rated 3.5 out of 5 by 10 reviewers.
Rated 2 out of 5 by Poor App we bought two of these lights and will be buying more however the APP does not work well - the new features which came out in Aug/Sept do not work - NEST does not work, Geofencing and Timer do not work. It appears that everyone is having the same problem with the APP. Luckily there are free app on the App store which allow really good features ( except NEST) Such a shame - nearly there but fails at the last hurdle. 23 September 2014
Rated 5 out of 5 by Really pleased with this product Lifx have done a great job with these bulbs. Everything with the set-up and working of these builbs has been smooth and seemless for me. Ok, we're waiting on some of the promised features to be release via an app update - but I'm sure they're working on that. Great that I don't have yet another "base station" to plug in to my router (as with Philips Hue). These bulbs are 'self-contained' in terms of their network connectivity. Two bulbs purchased, plannning my third! 22 August 2014
Rated 4 out of 5 by Great Product I bought my LIFX bulb with some apprehension - I'd seen the wonderful Phillips Hue light-bulbs, but I felt put off by the price and the requirement of a dedicated hub. While the LIFX bulbs are hardly cheap, they were considerably cheaper than the Hue bulbs as I did not need a hub - it was all built into the rather large casing. I've had the bulb for a few days now, and I'm very impressed by it - it's very bright with a wide range of colours and settings and is a perfect replacement for my old light bulb. While there are some features that are still missing (an iPad app and IFTTT support), the connected nature of the bulb means that these aren't too far away. The only downside to them is that they need to be switched on in order to use the app - even when turned off by the app, they still use up electricity for the stand-by mode, but this is to be expected with a device that needs the internet to function. Overall, I'm very happy with my LIFX bulb - it's something that I can happily recommend to friends and family. 02 July 2014
Rated 3 out of 5 by Disappointing 3 stars is about fair as 1 star would be unfair. Prospective purchasers need to be aware that this product is NOT dimmable! We bought this for our baby girls Nursery, the idea being we could have a nice baby pink colour for her room. It is fair to say that this is achievable but it is way too bright when anything other than the very vivid colours are selected. Having looked at the Philips Hue for a long while now the Lifx looked great as it had built in wifi so no need to purchase a bridge unit. The choice of colours is extensive, ease of use really is plug and play and no issues with the iDevices seeing the lamp. My issue is with the brightness. I am aware lots of LED lighting is non dimmable but we purchased a dimmer just to try it as I really wanted the lamp to work the way we wanted to. Unfortunately, due to the brightness we will have to return this Lifx lamp. Be aware that if you want the very vivid red / blue / greens and relative mixes then the lamp is at its least brightest. When you increase the brightness (to achieve the 'pastel' colours) that is where the lamp goes too bright. Such a shame, has lots of potential. 28 June 2014
Rated 2 out of 5 by Not there yet I was going to try the Philips Hue but instead went for Lifx. Once I set up the two bulbs in the same room I was able to control brightness and colours. When turning off at the light switch, as opposed to using software on the my iPhone, when next time I turned the light switch one two things happened: If turning off with a colour next time it reverts back to white; and when turning on, after about 10 -15 seconds the white lights briefly dim and then return to the previous setting. So far there is no way to set the lights externally via software such as IFTTT to come on and off. This would be a use security feature. Philips Hues can be programmed by IFTTT but I have not tested so don't know how good this is with the Hues. Next time around I will try the Philips instead. 22 April 2014
Rated 5 out of 5 by Revolutionary and accessible Fab light in itself, but also fantastic assistive technology - HUGELY cheaper and easier to set up than most disabled equipment and most home automation stuff on the market. Now iOS7 supports adapted switch access, this lightbulb and an iPhone or iPad can get you set up with assistive lighting in about, ooh, 10 minutes. Also can be used with wheelchair controls via iPortal or R-Net. The major issue with the software is that it's fixed to portrait mode so if you have an iPad fixed in landscape on your wheelchair, like most people do, you can't use the app easily/at all independently. Bummer. Really bad design in that aspect. Looking forward to the software evolving - especially hope to use these bulbs as dawn clocks, sunsetters, and also visual alerts (flashing them to attract attention of hearing impaired partner) and have already gotten them working a little doing that - hurray for the API! 01 April 2014
Rated 4 out of 5 by Great lamp, software not quite there yet. These lamps are fantastically bright at 1000 Lumens, the colours are very strong and you don't need a separate device to connect them to your wifi. They are large so do check that your lampshades are deep enought or that you are happy for them to be exposed. This is a fantastic product but you may need to wait for the app to be sufficiently developed to provide the sunrise / sunset effects and timers that you are expecting. Check the latest version of the app before buying. Another useful feature for the UK is that the lamps fit our bayonet socket lamp holders without an adapter. 18 March 2014
Rated 4 out of 5 by Very good! As a technology enthusiast I have been following LIFX since they popped up on Kickstarter. Now I finally got a chance to play with it and I am very impressed! The light is easily adjustable to what ever color you prefer and I can even exactly match the LIFX light with an existing living room lamp. It is kinda addictive because now I want more lights to play with... Of course, some features are not there yet but I will wait for the updates. 12 March 2014
