i alrerady had the amazing 6p from surefire. i bought a tactical bezel replacement and a spacer allowing for an extra battey. well the place on ebay i bought it from said its for the 6p/9p. after installing it with my exta bulb --p61 (120lumens) it came on or a split second and then nothing. and so i tried the backup bulb(p60)--same thing.. so i guess neither could hndle the extra power. what gives?
