Re: Vinhnguyen54 General Info Must Read
Thanks, gitd rubber bands... Or tape..
I use tritium fobs for some lights...they glow for decades all by themselves w/o needing to be exposed to light to charge them.
For others I use glow in the dark O-Rings. I slip the O-Rings over the light's bezel and body, etc, and charge them either by leaving them out in the sun, a room light, or, a UV light (Fastest charge). Once charged, they glow for a few days, but are fairly bright for about 12 hours, dimming significantly after that. The O-Rings are very cheap, I get them on CPFM for pennies apiece, and the 1" O-Ring can stretch and go around a 3-4" flashlight head, and fit in between the ridges or cooling fins, etc.
Reflective tape is good, especially if you use one light to find the others...as it flashes strongly when you sweep a beam across it.
They make GPS based transponders that you can attach, so that you can find the light or even track it if its moving, etc.
They also make shorter range devices that flash and/or beep, etc, when you hit a button on a remote (Kind of like finding your car in the parking garage by hitting the key fob...).
As far as water resistance, keeping the threads and rings greased helps a lot. Potting the electronics, so that stuff doesn't really move in there, helps a lot. Vinh upgrades the wires and resolders most of the connections to get good ground paths and heat conduction, etc...so, they are sturdier than the original lights in all cases. NO light is impervious to damage...even a tough light can just "land wrong" and get a shot at just the wrong angle, etc...its a bit of luck involved there...but, Vinh's stuff is never more delicate than his donor lights...he always makes it better in that regard.
If the light was never water proof to start with, say because it has a certain switch set up, or, a zoom head, etc...it will most likely stay the same in that regard. So, you'd pick starting points that have what you're looking for to start from...and improve accordingly.
