I have installed Homebridge and have it working nicely, but I have a question about light bulbs.

I'm going to get the Hue system at some point, but for the time being can I get a light bulb that will just work with Homebridge and without a hub? At the moment I have a Wemo Switch working with Homebridge.

Also, it seems hard to find Friend of Hue light bulbs in the UK. Has anyone found anywhere to buy third party Hue light bulbs in the UK?

Best wishes
