How do I rewire this sconce to accept a single, normal lightbulb instead of four small candelabra bulbs?

I'm looking to rewire this exterior sconce to accept a single, regular lightbulb instead of four small candelabra bulbs. My goal is to put a Philips Hue bulb in there.

I could probably rip it apart and figure it out, but I'm curious if there are any picture tutorials, explanations, or products that would save me some grief.

Yes, I realize it needs to be cleaned and there's a bird's nest on my house.

Thanks!
