#45190 - 07/27/05 12:28 PM Bobber Lights for PSK use? You be the Judge...
Anonymous
Unregistered


Reading John "Lofty" Wiseman's SAS Survival Guide, he recommends inclusion of a "beta light." Beta lights haven't been available in the US and I don't know if they're currently available anywhere for that matter.

Recently, I've seen several pics of several forum member's PSKs which have included fishing bobber lights as a replacement for the "beta light.". This got me very curious as to whether or not such a diminutive light would have merit in a PSK. I purchased two Lindy Thill Nite Brite lights yesterday morning for testing. You be the judge...



The Nite Brite bobber lights are 1 5/8" OAL by approximately 1/8" diameter. Weight is negligible - I couldn't weigh it on my current scale it's so LIGHT. Bad pun intended. They're advertised as providing 20+ hours of continuous light.

My test began at 1415 hours on 07/26/2005. I went into a completely darkened closet with the light and a copy of Greg Davenport's "Wilderness Survival." I found that the Nite Brite provided sufficient light for me to read by and sufficient light to easily identify objects within 3 - 4' from the light - easily sufficient to search a tent or pack.

By 2117 hours, same date and seven hours later, the light still provided ample light to read by and identify objects at close range with.



I could not use the light for safely traversing a trail with at that point (2117 hours) and I doubt that I could when the test first began. The light doesn't have enough throw to be able to identify a hazard such as a snake within a safe distance to be able to avoid it.

At 0300 hours on 07/27/2005, twelve hours forty five minutes after the test began, the Nite Brite was still providing enough light to read by and search distance had diminished drastically. I could ID objects in my pack at 2' from the light or less. As a side test, I used the light successfully to let me see to tie a fish hook with a palomar knot.

By 0530 hours, fifteen hours fifteen minutes after the test began, the light was severely diminished. I could read by the light at near contact distance, but trying to ID objects at 1' from the light was challenging. Trying to tie another hook wasn't possible at this point.

By 0730 hours, seventeen hours fifteen minutes after the test began, I could only read by the Nite Brite at contact distance.

It's now 0815 hours and the Nite Bright sits before me, a full 18 hours since the test began, burning dimly, but still burning. I can still read a few words at a time at contact distance. Pretty amazing performance, in my humble opinion.

Kit worthy? I think so. How about you?

Good Morning Sargeant:

Here is a source for the Beta Lights that Wisemann makes reference to:
http://www.betalight.com/

They cannot be imported into this country because of bizarre and outmoded regs of the NRC.

Most of you guys already know my opinion of these things. I love them. I keep one in my belt kit as a backup to my Photon II and I keep two in my pocket kit a my only source of artificial light. I find the red to be brighter (perceived brightness perhaps) than the green. I haven't tried any other colors yet.

Thanks for the post SGT !

I have been wonder about those also. I also bought one a few days ago and have done the dark closet test, but have not tried to see how long it would last. While I would not want to read a book using it, it did give enough light to read and at least gave enough light to be able to find things in a dark room.

Anyone have any idea about storage life on these?

You could fit several of these in an altoids psk. I think I need to go get some. Wall-mart right? <img src="/images/graemlins/grin.gif" alt="" />

Size/shape of replacement battery reminds me of the pin lithium that powers this red LED micro-flashlight.

No offense, man, but it is no different than tritium sight inserts. Lots of us have those on pistols. I have them in my watch! It is less radioactive material than you find in an old smoke detector.

I dare say that if the regulations are the reason why, it isn't becuase the Dept of Energy said no, but becuase SBR didn't want to fill out paper work. More likely, there is a percieved lack of a market. People see that radioactive trefoil, and they run. Silly humans.

I purchased one.

For 5$ (canadian funds), it's not a bad buy. It's so small, it can be added to pretty much any existing kit, of any size. I added one to my camera bag PSK. Since my kit is a wilderness kit though, I would have a tendency to use a mini-Bic/matches before readying the bobber light. It might find it's place in an Altoids kit someday.

I saw them on the Bass Pro website and on Lindy's website - but both were more expensive than what I'd paid...
