The Hue Bloom is a separate lamp, not a "light bulb" with an E27 base or something. Unfortunately, I cannot say whether the bulb of the Hue Bloom can be exchanged and which base it has (lamp not yet unscrewed). However, I am very satisfied with the Hue Bloom as a table lamp to better illuminate my work area on the desk. Currently, I control the Hue Bloom via Bluetooth (Philipps Hue BT App on iPhone), but I could also integrate it into the Hue system for routines via Hue Bridge. In order to control a lamp with an E27 base, it needs the Hue Bridge (unless it is the BT version of this lamp, in which case it does not necessarily need the Bridge, but it is recommended). Digitec has various starter kits for E27 lamps. Often only the price differs (because of different suppliers), sometimes also slight differences in the kit content. It is also important to note whether White Ambiance or White or White & Color Ambiance is selected. I hope this helps you a little.

No, you still need the hue Bridge.
