Cracked lens on my Jetbeam iii military

The title says it all. I was on a domestic call and the intoxicated husband wanted to try to get one last swing on his wife while the police were there - which didn't happen. What did happen, is while I was holding my flashlight to illuminate the house (which had no working light bulbs):shakehead, the husband lunged at the wife and I tackled him down to the ground and cuffed him without any more incident, and placed him under arrest. Unfortunately, I dropped the light onto the ceramic floor during this brief altercation.

Well, the light stayed on, and the body, bezel, and tailcap guard are still in near new condition. However the tough "sapphire lens" I read about, is cracked from one end to the other:

of course, this affects the beam:

Now a little rant; how can this flashlight be intended for military or military-type purposes if the lens cracks after a 3-4 foot drop? Am I asking too much from this light/lens? Should I just be happy that the light still works and the finish is still intact? Should I be glad that it only cracked and not shattered? I have an Inova t5-mp that survived a 25-30 foot drop onto asphalt and the light remained intact and in working condition with only a slight chip on the bezel to show for it. I can understand a non-tac, non-military, walk-the-dog, path illuminating light might not be built to take a beating, but I'm seeing lights like the Fenix Tk40 being boiled/froze/dropped/dragged on the ground while tied to a truck on a gravel road/etc and the light still works and the lens isn't cracked. I've even seen a Nitecore d10 dropped about 6 feet from a bed repeatedly and still funtion flawlessly with lens intact.

Rant off, now for something more constuctive. What should I do now? I ordered the light from bugoutgear.com about a month ago and I still have the receipt. Should I contact them to see if they'll replace it? Is there an aftermarket lens that will fit on the Jetbeam iii M? If so, where can I purchase it and how do I replace it? Do need a special tool to unscrew the bezel? The new "artifact" in the light really doesn't bother me. It's the fact that it's a brand new light to me and I'm worried about water getting in there as well as the lens shattering the next time a strong breeze comes along :whistle:

I'm not bashing Jeatbeam or the iii military in anyway and I dont' want to flame and start a Jetbeam vs. whatever thread. I like this light alot and use it everyday - and I want to continue to do so. Therefore, I'm going to chalk this up to just an akward rare drop that caused just the right pressure/shock to crack the lens. I just can't beleive such a slight jolt cracked the lens, and I'm more angry that I have to go through the motions to replace it more than anything. Any help would be appreciated.

Thanks,

Jeff
 
Hello,

Sorry to hear about your lens cracking.
I have a Jetbeam III M that I just purchased from BugOutGear.
I also purchased the Low Profile Crenulated Bezel and while swapping it out I noticed a design flaw in my opinion.

You know the clear o ring that is in the head assembly...I found two smaller (thickness) ones and put one on each side of the lens. I measured them by eye at the local hardware store.....Plumbing dept! If I was to guess I would say the o rings are 28-30 mm.

This is what I did for my own piece of mind. I am no expert.

I am sure that BugOutGear will be able to help out with a replacement lens if you contact them.

Good luck and be careful out there officer.

P.S - judging by your post and avatar my mouth is really watering for a Chicago Hot Dog, thin crust pizza and a Italian beef.

Sapphire has great scratch resistance, but doesn't do so good when it comes to impact. :(
 
That sucks to hear :(

Hopefully you get it sorted out so you can put it back into use, minus the big crack in the beam!
 
Sorry to hear about that Jeff. :(

To replace the bezel, you'll need a bezel removal tool like this one:

You may have to contact Bugoutgear or Jetbeam to find out the lens size and see if you could find one here: http://www.flashlightlens.com/

From what I know is that the Jet-III lens is about the same size as the Surefire 6P/C2/G2/M2, etc lens. But you should find out to be certain.

Sorry, can't be any more helpful. Good luck in replacing the lens.
 
Now THAT is Customer Service...way to go. I know where I will be ordering my next batch of AW protect 18650's from. Be careful out there Jeff.....and remember......zombies hate the smell of brass. Good thing you cuffed the husband before he tried to eat your brains....no wonder they had no working bulbs in the house- they also have excellent night vision.:sick2:

That's the kind of service I like to see :thumbsup:

I wonder how did the fall landed? I'd personally expect a bit more from Jetbeam products. But i do understand scratch resistant lenses usually means its easier to crack. There's kind of like a inverse relationship there.
 
It was discussed in depth a while ago and the consensus was that ceramic tile is the worst surface for a light to hit. Apparently the forces generated from even a 3-4ft. drop can be tremendous. Don't know much about jetbeams but seems like it fell on just the right (wrong) spot and your bezel suffered the wrath of the ceramic floor. Glad everything turned out okay and that you'll have a replacement quickly.
 
I love my JetIIIM. It started my addiction. Glad I purched from BOG. Great CS. Good luck be safe.
 
Flavio, ButOutGear ROCK!!! I just bought a few JetBeams from him / them. Fast shipping, and now this? That is service at it's finest.

NICE JOB BUGOUTGEAR !!!!!!
lovecpf
 
I can remove the bezel ring on my Jetbeam easily with the tool that removes the back of wristwatches for battery changes/repair. The tool I have has 3 individually adjustable pegs that fit perfectly. The bezel has 6 indentations, but this tool seems to work just fine.
Watch Forums have the for sale sometimes, and there's always Ebay.

Tiles are a terrible thing to drop anything on! :shakehead

However, I dropped my M6 on my tiles the other day... sorry tiles :devil:

M6 - 1
Tiles - 0

:D
 
Jeff,

Yeah, I had no idea that sapphire lenses were scratch resistant but not impact resistant until today. It's interesting that the jetbeam iii military would use this lens vs the jetbeam iii pro instead. You would think the more important issue for the former would be impact resistance vs scratch resistance. Either way, i'm glad I posted this small problem here. Thanks again to all the good advice cpf members and flavio from bugoutgear!

:thanks:
 
Hello,

P.S - judging by your post and avatar my mouth is really watering for a Chicago Hot Dog, thin crust pizza and a Italian beef.

Now I'm hungry too...

Don't forget about the infamous breaded steak sandwhich, I can't seem to find that out of the city limits, let alone out of the state.
 
Hello Jeff I would just chalk that one up to bad luck as the drop probably hit just right to cause the crack.

I wanted to mention i have been able to unscrew both of the SS bezels on my Jets by just using the bottom of a boot or shoe and applying pressure and twisting the light. Both of mine loosened up really easy without much effort.

I've heard of people using the rubber on the bottom of a computer mouse pad also.
 
Other manufacturers, mainly RA, use two O-Rings like a sandwich with the lens to protect it from drops. This is just like 13Lites suggests.

If your light falls, and the only thing the lens has to hit is a soft washer, it will be difficult to break.

I wish I could find that construction diagram of RA lights that shows how they protect the lens.

Here's a nice quote from the RA website:
This production Ra Twisty was dropped repeatedly from a height exceeding 6 meters (20 feet) on to concrete, pavement and rocks. After over 20 drops, the light was repeatedly thrown at concrete, pavement and rocks. The light still functions normally. The glass lens did not break even with this severe punishment. Can your flashlight survive this kind of treatment?

*edit* I found it!

3. The lens is made of ultra-clear glass with an anti-reflective coating on both sides. This allows the glass to transmit roughly 98% of the light from the emitter and reflector. The glass lens is made extra thick for additional strength. Finally, the glass is protected on all sides by rubber cushions to allow the glass lens to survive extremely rough handling.
