For how long will a relume last?

[Migge]

Hi all,

i was just wondering if i send my watch for a reluma, to ex Vaccum, does the lume
last? Or is it something that has to be re-done in a couple of years!?

Regards

Mike

I would think it would last a good 10 years or so, but I am not certain the answer and think it is a good question.
Is there any drop off after say 3+ years in luminoscity (spelled wrong) may be the better question to ask though, it may offend a prefessional to imply that you would have to relume every year or two.

considering the the strontium aluminate "super lumes" have only been around since the early 90's its probably too early to really tell how they will degrade... but everything degrades, even tritium has a half-life

Actualy tritium has the shortest life of all. Five years or so and you would be thinking it's a bit dull. It ain't as bright as supalume either. Still, it doesn't die down in a few hours like luminesent coatings. It realy is luminius as opposed to just storing light like a normal lume. If it was available easyiley it would still be my choice.

For the OP, here is some reading on Lume.

Hope that helps.

No doubt there is quite a bit of knowledge on this forum.

Thanx for the answers and the links.

Its a tricky question.

Most current luminous compounds themselves don't degrade with age unless exposed to moisture. The part that is most likely to be affected over time is the binder used, this is basically a varnish and can yellow with age and exposure to strong light unless very carefully created. Manufacturers spend a lot of their research time developing binders that are both free of UV filters and still resistant to discolouration.
