The existing (old) Flourish simply has a bulb holder. You can fit a 1100 bulb in it, perhaps even a 1600 lumens one. Good luck trying to find the lamps though.
Philips Hue is about to release a new version of the Flourish table light. This upgraded smart lamp appears to come with a new light source, offering a higher maximum brightness level. Plus, it is Matter compatible, and users will be able to use MotionAware technology when connected to a certain accessory.
