The Aerobie skylighter is basically the superdisc ultra with 2 super bright White LED's pointing out from the centre. The effect is to light the whole disc up without reducing the long, stable and accurate flights that we come to expect from Aerobie discs. The Skylighters's soft rubber edge provides a great grip for strong throws. It also feels soft to catch and does not develop sharp scratches and burrs like a conventional disc when it hits pavement. Size: 12 inch diameter. Weight: 162 grams.
