Looking for solar powered flood lights that can be linked to a remote control. Anybody know of such a thing?

I'm looking for self-contained bright flood lights I can clamp to trees and eaves, with built-in batteries and solar chargers. About a dozen of them over a 100'x100' square. But I need them to all to come on with a single button push on a wireless remote.

I don't need them to be motion-activated. I won't ever need them to be on for longer than an hour at a time.

Most "solar powered remote control lights" I see on Amazon and elsewhere seem to use the remote to control their motion sensor settings, or I suspect they're line-of-sight remotes. I think I want something more along the lines of radio controlled.

I am considering building my own out of UPS batteries, battery tenders, and cheap LED lights, but I'd certainly love if somebody already made what I'm looking for.
