Sup Beam K40 not working.

Blindguy · Mar 15, 2014

I just received my Sup Beam K40 today. Got it loaded and.... nothing. :shakehead
Checked the battery pack. 12.56v (3 18650's)
Checked each battery: 4.17 - 4.17 - 4.2
Checked the tail switch.
To the solder joints it worked. On & Off
From the small inner spring to the larger outer spring, it did not have any continuity.
I'm waiting for an email back from the seller.

Does it sound like the switch circuit board is bad?

Sorry to hear this. But I hope the seller will reply asap. That is one great thrower and wanted to have one also. Soon.

Btw, try to check the magnetic switch. It must be on the standby mode. For me the small spring may not necessarily have continuity with the large one. This serves as an addistional "cushion".

OK, I just ran through everything again.
The head is good.
The battery pack is good.
The tail switch shows good on the soldered sided. Click on, click off - through ohm meter.

I just put everything back together and now it works.

oo:

I did not change anything, I swear.
I dunno.

What I can say I really like about it is the .6 lums. For such a powerful light, it's nice not having to dig out my EDC to read by. This K40 does it all.

(I still suspect that tail switch and will be keeping an eye on it.)

You may just have dirty connections. Sometimes just cleaning and relubing a light makes a big difference.

PSST! return it and get a K40vn instead...

dc38 has a point. You don't have any idea what that shell is capable of untill you see what a beast the K40vn is. At least 3*the throw and double the lumens.

I bought this off of fleabay from a good seller. They don't seem to have the K40vn.
Is it something I can upgraded later?

Not exactly, it's a custom modded version...from someone in your state, nonetheless lol.

Search the forums for "k40vn", the modder is vinhnguyen54. Great guy to talk to, great guy to deal with.

I'll keep this in mind. I guess I'll just use it as is for a while. If I get tired of it or win the lotto, I'll mod it then.
This is the first real "high powered" light for me so no need to go off the deep end... at least for a while.
I'm just glad mine is working.
