the ones made by traser were the brightest (traser make the little vials in the watch posted above) but they don't appear to make them anymore.When I read they were Tritium I was going to give an explanation, but didn't have time to get everything exact, so didn't post
What he said
Are there any "higher quality" ones therefore?

also, the traser ones were the ones where the plug fell out if they were handled roughly which allowed the sapphire glass tube to fall out.
i don't know who make decent ones these days.
the one i have is a traser one and its all plastic, but that was bought a long time ago.
no, the exterior is plastic, but the tritium is in a very strong sapphire glass tube lined with phosphor.
If you were in near complete darkness it certainly shouldnt be, ive had mine for about a year now and its still a lot brighter than that, it should be that intensity about 3 or so metres away..is it ment to be this dim?

That was with the camera on the box of it guess I got a crap one then![]()


Hmm...I'm starting to think I have a dud one as well. It's barely visable?![]()

Nice - thanks for the explanation... it did make sense, but as I'm not a geeky scientist I couldn't tell if you were feeding me a few porkies or not. Sounds convincing though, so gonna try and find a good quality one of theseScience wins, naysayers lose. awesome.

and mine is still going strong, it's fairly bright as well in the dark and has helped me find my keys numerous times.
