The light source can also be controlled and dimmed directly with a smartphone or tablet without a Hue Bridge via the Philips Hue Bluetooth app, provided it is Bluetooth-enabled. Control via app works directly via Bluetooth without the need for a bridge. However, the range of functions without a bridge is somewhat limited compared to control with a bridge.

Yes, you can if you have installed a Hue Bridge in your home. Then you can control all Hue lamps and, for example, put them on a feller switch. I have 2 of them in use.

I don't have the same rotary dimmer. When I turn it down, it starts to flicker. However, everything works when turned up all the way. I can control and dim everything as usual via the app or my own local smart home.

yes, with the philips dimmer or via the hue app ;)

Yes, screw in connect. The control module is in the bulb. However, a Hue Bridge is necessary for control.

It's the new 1600lm version. According to its specs @ Philips, lumen output is 1551lm @ 4000K and 1200lm @ 2700K. Formfactor is A67 not A60 - so its quite larger (67x13.1cm) than others (60x11cm).
