It looks like a pretty compact alternative for a 2-CR123A light. Is there anything wrong with the bulb that came with it, or do you just prefer the Surefire P60? How is the build quality in comparison to Romisen?
I'm just playing around, swapping in and out different Xenon modules. My P60 module draws 1.14A. While the TOP OEM module draws 1.18A and has a whiter tint with a bigger/rounder hot spot, so its a better module all around than the surefire.
Quality is on par with my 6P. Butter-SMOOTH threads with well lubed O-rings that fit very tight with mating parts. Its definitely a water/air tight assembly. Unscrewing the bezel and pulling it out of the body you can really feel the vacuum suction, even more so than removing my 6P bezel. My daughter went night swimming tonight and submerged it a couple feet. Definitely shallow-submersible. As far as build quality goes, I would put it a notch above the RC-C3 and a smaller notch above the RC-N3. The O-rings on those lights are effective, but they are too small to really "feel" solid.
The anodize quality on the TOP seems thicker that the Romisens and more robust. It has a "warm/satin-ey" kind of feel. Like the difference between a Titanium and stainless steel dive watch.
