Recommendations for 48v led strips, or for waterproof 48v->12v voltage regulators?

[geekeasy]

I've got a spare 48 plug on my XP Lite and I'm thinking of adding some fun led lights to it.

Unfortunately, searches for 48v led strips mostly turn up 12v strips with 48 leds. So, I'm looking for recommendations here.

I'm also open to adding a small, waterproof voltage regulator and going with 12v strips...
