So I play airsoft. I put my M952 on my P90. the M952 has a detonator and is running a P91 bulb. Check out the video. At 0:19 secs in you can see a guy pop out and shoot out my M952 head lens. the glass explodes but the light keeps running.

I didnt notice until after the game. Here is the aftermath.

Oh.... LOL... Right.

Thats cool that it still worked despite the punishment.
Cool vid footage BTW:thumbsup:

i think he focuses his comment on the M952 still working even after getting a direct hit on the head, doesnt sound like a complaint on the broken pyrex window, i could be wrong but thats how it sounds to me.

is that a marui?

You hit it right on the head. Yeah, Im not complaining, I love surefire. Im jsut a little surprised that even with a FPS limit of 350 with .2g bbs, that the glass lens could break. but Im not dissapointed, the light did its job.

Yes it is a marui, there are only a few GOOD P90s. Toytec and Marui. Classic Army has yet to make their sportline model.

If you are interested here is the longer version of that video. I destroy a National Guardsmen and the team he is on.

LOL, the kids near the end of the vid just lined up even after your first attempt. Just waiting to be shot at - firing squad style :devil:

From your vid, the light turns on & off beacuse of the shock isolation?

Musta've been a really direct hit on the glass for it to break at 350fps.
Good game.
 
No the max limit is 350 FPS. No one really runs guns that hot for CQB, specially not the noob that shot my light out.


The rapid blinking is the strobe feature of my Blackhawk Night-Ops Gladius. I was using two lights in that game. Gladius and SF M952.

I use the Gladius for offensive purposes, to disorientate the opponent and gain a tactical advantage, the SF is 200 lumens to blind and see my BBS (sort of a psuedo-tracer) to make sure they are going where im aiming, even though I have an aimpoint red dot. it never hurts to double check your aim with 200 lumens of SF power.
 
That sucks... but it still works. Tokyo Marui makes some good airsoft guns never got around to buying the P90 version lucky you.
 
I plan on calling them tmw. I know I could jsut go and get another lens. but I dont see why they wouldnt replace this. It was not abused, just used as it is supposed to be. I mean it was airsoft bbs. not real steel bullets. It broke while in usage and on camera no less.

They even replaced the damaged parts for that guy, who's brother in law threw his 6P in the air a bunch of times. That is blatant misuse.
 
I'm sorry, but what does this showcase about the shock isolation? 1.14J isn't going to significantly change anything's direction.
 
I would imgine that force that is strong enough to shatter a surefire weaponlight. might cause the lamp fillament to break. It is understood that while a incan lamp is running hot, it is more susceptible to breaking due to shock, hence why SF made shock isolation in their millennium series lights for tactical situations.

What I'm saying is that the BB doesn't have enough energy to change the velocity of the lamp module enough to break the filament unless it breaks the bulb and displaces the filament directly.

The SF shock protection protects against the effects of velocity change of the light on the filament of the bulb. The impact of the BB, a short-duration impact, won't make the light change velocity.
 
good point. But don't you think that the force to shatter
The lens might be enough to break a light w/o shock isolation?

I do not. Breaking the window in this manner results in little to no energy being transferred to the rest of the light.

And 1.14J, the maximum possible energy for this scenario, will only break VERY delicate lights.

not to argue but you said that VERY delicate lights would break. However I don't think surefire lights can be called delicate. Possibly the intense heat of the light makes the glass susceptible to breaking

The fact that glass is very hard and very brittle and doesn't flex very far makes it susceptible to breaking. Add to that the energy of the BB over the small area it hits, and that's enough to flex the glass enough to break it.

By 'break' in my earlier post, I meant 'cease to function', which the light didn't.
 
Solscud007 -

Certainly having the shock isolation didn't hurt matters, yes? How about a mental exercise? Wearing thin gloves and safety glasess, holding only a lens (window) between your index finger and your thumb, blast that lens point blank with an airsoft BB. Maybe dial down the power to a little less than 240 mph to make up for the drop in speed over distance. How about 200 mph for 293 fps. Do you think you'd feel some shock even if the glass broke? I think so. It's hard to quantify how much shock it takes to break a hot, soft, boiling tungsten wire.

Take it from another angle. If you didn't have shock isolation it's possible that the glass would have exploded more violently and thoroughly allowing the projectile to make contact with the lamp.

Anyway, cool video. It seems that your lights were giving you opponent a lot to think about. Yeah, I watched it like ten times.
 
IM curious where was your camera during all this, in your hand on mounted somehow due to the fact u also had the Gladius in hand i guess.

The window isn't shock isolated. Only the lamp assembly.
 
Shock isolation protects the bulb from recoil. It doesn't prevent harm from projectile impact.
