M91B, M91BN, and M91BW Dropin to fit Surefire 9P

Great Dropin. Extrem spill and good throw. I use it in a 9P with A19 Extender and 2x protected Keepower 16650.

Excellent product, truly well-engineered, pleasant light, very well-designed beam.

Wowsers!

This is a major upgrade for my old z3 surfers combat light. If you’re not careful, it’s easy to temporarily blind yourself. I use my light daily out in the country at 3-4am feeding horses. I scan out over distances of up close to as many acres as it will allow. It will allow me to clearly see things at roughly 250 yards and it goes further but starts to fade in clarity. There is no single flood or spot, the beam somehow does both close and far with zero change in color or light density. It’s pretty astonishing really. It lasts a whole lot longer with the battery life also. The old bulb would eat through batteries rapidly and got hot quickly as well. Not this one by comparison. Solid brass and a nice reflective bezel. Zero complaints, and was cheaper than a new light. No need to get a new holder and change gear set up ect.
