We now have available SuperBright Procyon GanzFrames. These incorporate 12 LED: 3 blue, 2 green and 1 red per eye, making them the brightest on the market. So if you'd like your Procyon experience to be even more intense, these would be the perfect accessory for your Procyon. They work with any Rev 3 or later Procyon... that is, those with a round and not rectangular GanzFrame jack.
Very happy with this item!
