Wi-Fi and the app Our range of Wirelessly (Wi-Fi) controlled, energy efficient LED light bulbs can be controlled via your smartphone or tablet using our free lighting app. Unlike a lot of other bulbs on the market, our lamps are controlled via Wi-Fi, not Bluetooth meaning you can control the lights over a much larger range. As long as you have a Wi-Fi connection, you can control our bulbs. The app allows you to do the following: Multi Zone You can install multiple light bulbs into a room / zone and name that particular zone on the app, you can also set-up additional zones on the app if you wish (living room, kitchen etc ). You can then tell all of the WiFi lights in that selected zone to either turn on/off, change colour or adjust brightness (see below for more information). The app gives you the freedom to control all lights individually or per zone at the same time as you see fit. On/Off The app lets you turn on/off connected bulbs. You can still simply turn the bulbs on/off using your existing light switches, just make sure that your light switches are set to on if you want to control your lights via the app. Colour Changing and Dimming Our WiFi light bulbs are tunable through the white spectrum of light. Using the app, you can set these bulbs to either warm, natural or cool white to suit your requirements, you can also dim each bulb using the app to set the desired mood. please note, bulbs will power up to the last used light settings when the lights are turned on.Timer Each bulb can be set with a timer to turn on and to turn off. You can set multiple timers for different days in any number of patterns to suit you. Energy Efficient and Long Life All of our WiFi bulbs use the latest LED technology, each bulb has a diffused shade which softens the light without reducing its brightness. In fact, this bulb is rated to 9W, thats equivalent to a 60W incandescent bulb. Each bulb has an average life of 25,000 hours (after 25,000 hours, the bulb will only reduce in brightness slightly and will continue to operate at a minimum of brightness of 70% of the original output).Further Information We have tested up to 15 light bulbs on a single app across multiple rooms/zones with excellent results. If you wanted more, please let us know but this is usually enough for most domestic installations.If you want more than 1 user with access, you can download the free app onto multiple devices. You can also set up a password on the app to stop any mischievous family members playing with your lights.
