LIFX Original A21 RGB Wi-Fi Smart LED Light Bulb - White




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 0.2W and 17W, depending on brightness level and can last up to 40,000 hours, or 23 years based on 3 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 80kg 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.




The Light Bulb with an Incredible Life Span

LIFX is a WiFi enabled, energy efficient, LED light bulb you control with any smart device.

With an incredible life span of 23 years (based on 3 hours/day), LIFX allows you to see your home in a new light. From warm white to cool white and millions of colours at your fingertips, LIFX helps you match your mood, compliment your surroundings and synchronize with the time of day.


Cheaper than a Normal Light Bulb

With superior illumination, LIFX bulbs shine as bright as your standard 75W incandescent light bulbs but only use 17 watts. With a simple swipe you can choose from warm white to cool white, and millions of colours.

LIFX uses the world's most advanced light dimming system from 100% brightness all the way to 0%, and anything in-between, with just a touch.
