While July is just about the hottest month of the year for most Americans, ThinkGeek is planning to make Star Trek fans shiver like they’re on the icy surface of planet Alfa 177 with this year’s upcoming San Diego Comic Con-exclusive release!

Based upon Lieutenant Sulu’s misadventures in “The Enemy Within,” where he had to heat up rocks with his phaser for the stranded landing party to survive in freezing temperatures as low as 120° below zero, ThinkGeek’s Star Trek Phaser Controlled Rock Mood Light will debut at their SDCC booth (#3349) during the convention.

Mimicking a phaser-blasted stone, the $70 set includes a “replica first-season Type-1 Phaser” (rather than a Type II phaser, as seen in the episode) which will trigger the inner lighting of this product to glow like in the classic Trek episode, along with “a whole spectrum of relaxing atmospheric settings” to “provide an ambient glow in numerous colors.”

It also includes a “Starfleet-issued” emergency survival blanket to keep you safe from the cold.

Announced via StarTrek.com this morning, the ‘Rock Mood Light’ will be available to San Diego Comic Con attendees when the event begins next week, and we expect it to be available for purchase through ThinkGeek.com  sometime later.
