I just wanted to share a problem that we're having with Princeton Tec Aurora headlamps.

A few years ago I bought an Aurora for each member of my family - for camping. Eventually I replaced mine with a PT EOS, which has a friction clicker that helps hold it in place and has done me very well, plus it is a LOT brighter.

After a year of Scout campouts, the hinge on my Son's Aurora started loosening, causing the headlamp to flop down. He tried wearing it upside down, but then it didn't aim properly. I used the Leatherman to tighten it, but the big phillips driver was too big, and the tiny one was so small I was afraid I'd strip the slots. I tightened it when back home. It loosened again fairly quickly, so I replaced his with an EOS.

Last weekend while in Eagle Cave in Wisconsin my daughter's Aurora did the very same thing. Again, I didn't have the screwdriver with me (it was in the car) so she carried it in her hand. After I got home I ordered new EOS's for my daughter and my wife. Now the Aurora's will be limited to home use.

Now my only problem is that the EOS is so darn comfortable that I put it over my winter hat and forget it is there, so when I pull my hat off the EOS goes flying. Its happened twice - once on a forest floor and last weekend on a concrete cave floor. Luckily it didn't break and didn't even scratch.

Sounds like a job for a little dab of Loc-Tite to me.

I once used Loc-Tite to secure the screw on a shower knob that kept coming loose, and the stuff melted right through the plastic and destroyed the knob. Obviously it wasn't the right stuff to use.

There are various grades of Loctite, try to find some purple Loctite which will keep the hardware from loosening but will not be as coorosive.

Just use your SAK or multitool to tighten it down when necessary. Dunno about loctite, I haven't used that on mine.

I've had luck solving similar loose-thread problems with a wrap or two of white (plumber's) Teflon tape around the offending machine screw. Fills the loose threads a bit, and creates enough friction to improve screw retention.

I've had a couple of mine loosen up on me like that, but a quick tighten with a Phillips solved the problem. You might try putting a drop of clear fingernail polish around the screw head after tightening.

Slightly OT, but is the EOS on low power suitable for reading? I use my Aurora for reading in my camper sometimes, but I'm thinking of getting an EOS for the longer throw when I'm outside.

It depends on your eyesite. I tend to prefer the medium setting for reading, but my eyes are getting a bit older and I need bright light for reading. I almost always use the lowest setting inside my tent at night - when putting gear away and setting up stuff for the night.

When in the cave camping last weekend I tended to run the EOS at the medium setting. It was plenty bright enough to see where I was walking and I wanted to save the batteries since the cave called longer usage times. I used the high level when lighting up other people's gear - to help them find whatever they were looking for.

I do think you'd find the EOS just fine for reading - one of the two lower levels would suite your needs. I certainly like the high level's throw.

My Aurora's primary function in life is at home - I use it for reading when my wife wants to sleep.
