Smart LED WiFi bulbs are a great introduction to changing your house in to a smart home. Our selection has been carefully chosen for their quality but also their ease at setting up. No additional hub is required for our TCP wifi bulbs. They can be controlled via a free down loadable app for your smartphone or you can use a smart device such as an Amazon Alexa or a Google home hub. You can group bulbs together to create collections of lights which allows you to ask a smart device such as Alexa to 'turn off the living room lights.' You can also create certain conditions such as 'ok Google set up family film night,' which you have created on the app, dimming the lounge lights by 60%! The possibilities are endless. If using the app on your phone you can control the lighting from anywhere in the world which is great for security.
