I'm here, although I've never been refered to as a guru before.
I looked at the specs and yes it looks like it should fit without a problem. The opening in the lamp housing is 1" (25.4 mm) in diameter and the lamp is listed as 25 mm in diameter. The length is not a problem, lots of room there, hopefully the manufacturers specs are correct.
I did notice that the seller lists them as out of stock until about June 26 though.
