80+ lumens from 7 watts... Geez, some incans are more efficient than that. According to QuickBeam's Dec. 12 review, the 8W Wolf Eyes D36 ($13) used in the Wolf Eyes 6M Explorer delivers about half again as much output and half again as much throw. The smaller D26 ($12) won't throw as far but should deliver the same output and can be dropped into a Surefire. Better yet, just get a Wolf Eyes.
