Surefire throw 6p vs 9p

[pilot4x4]

How does the throw of a 6P (or other Surefire with P60) compare to a 9P (or other Surefire with P90)? I've never used a 3 cell Surefire and would like to get an idea of how it will compare to my G2 or C2. John

I used both bulbs. The throw is the same, coz the reflector is the same. 9P had a bigger hotspot and the spot is oval shaped.

So would it be safe to assume that if I was to run a P61 in my 2 cell Surefire that it would give me a beam about equal to that of a 3 cell running a P90? John

pretty close, any small differences are no greater than the differences between individual globes of the same type on the same batteries...

9P had a bigger hotspot and the spot is oval shaped.

Thats spooky i was just about to start a thread about my oval P90 spot in my 9P , i thought it was faulty , so this is normal for a P90 ?

It is normal for SureFire to focus as much as the light as possible into the beam. This means if the filament is not a point [source] (which it isn't) then the beam will not be a point (round).
