LIFX is a Wi-Fi enabled, multi-coloured, LED light bulb that you can control with your iPhone, iPad, Android smartphone or tablet. 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. LIFX automatically connects to your wireless network, making set up easy and can be used in conjunction with multiple LIFX bulbs in one room. This energy efficient bulb consumes between 0.2 W and 17 W, depending on brightness level and can last up to 40,000 hours, or 25 years based on 4 hours use a day. With 4 hours use per day, your LIFX bulb will pay for itself in approx 4-5 years and will reduce green house emissions by about 80 kg per year. It features a brightness level of 1,017 lumens, which is similar to a 75 watt incandescent light bulb but 4 to 8 times more efficient.
