Zex LED purge illuminator

I was paging through the new Summit magazine (page 289) and saw these devices that are supose to illuminate your nitrous when you purge in either green red or blue. I think this is cool. Has anyone used one? Does it have to be hooked up to Zex systems or can I hook it up to my NX purge?

Thanks:
