A:AnswerIf by HUB you mean the Bridge the answer is YES. You do need one. Light bulbs can be paired with a dimmer switch directly without the bridge. So far the description reads strips require a bridge to work.
A:AnswerYes you can buy any Phillips Hue Bulb and it will connect with the Hue Bridge that comes with this starter kit. I currently have 9 bulbs and some are color and some white.
A:AnswerYes! They are beautiful. We used a home consultant from Best Buy and have been working in phases. Such a great addition! Increases hands free and safety !
A:AnswerThey are not rated for outdoor use but I am using the Hue white bulbs outdoors. Both of the spots I use the are well protected from the elements but I do not know if the change in temperatures will affect the life of the bulb. They have only been in use for 10 days.
A:AnswerIt does not use the WiFi. It uses a direct wire connection to your router/switcher.
Hue uses ZigBee to communicate in between devices thus leaving your WiFi network free of any interruptions and unnecessary
broadband congestion.
A:AnswerYes. Use the Philips hue app, and tap the three dots in the right corner. Select edit or add lights, then click search and you should be able to see the new bulbs.
