This bulb does not change colors. This bulb is only a soft white at 2700K.
We have a great YouTube video that shows how to use the Hue app to connect a new bulb https://youtu.be/VqsrDIEfqk8
Yes, absolutely. And the bulbs can be controlled together as one 'unit' or individually.
Hi Dil, it looks like this Philips Hue 100-Watt Equivalent A21 LED Dimmable Smart Wireless Light Bulb White with Bluetooth is a store exclusive item and only able to be bought in a Home Depot store. Unfortunately we do not sell it with online stock for purchase. If you are unable to see the store inventory or price it is most likely either not a stocked item in your area or no longer available for purchase from Homedepot.com. I would advise you visit or contact your local Home Depot store for pricing and availability. Please follow the steps below to localize your Homedepot.com: 1. Localize Homedepot.com using your zip code (My Store Location: Change) 2. Choose the store where you want to pick up the item (Make this my Store) We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot!
