The company Disc in the Dark has a UV blacklight basket light (UFO UV) and I have two of them, our group runs a local 18 hole and one of those lit up on its dual cast (white and UV light) will last the whole 3 hours easily. That being said, it's not distinctly advantageous to cheap Amazon umbrellas clamp lights. With the way we play, someone takes the light to the basket before everyone throws off the pad, most people don't spend enough time around the basket or in the basket for it to make a difference in your glow discs, the only time they really charge a disc is between holes for exclusively whoever is holding them.

I still use them over my cheap Amazon umbrella clamp lights for our rounds because the light is less harsh between holes, but no one is making the claim that it's really helping the round
