Degradation of superluminova paint

[meoramri]

Hi,

Was wondering the effects of UV light on the level of degradation of superluminova paint, especially natural UV versus artificial UV light.

Articles have been written about the effect of natural uv to the degradation of superluminova paint but can't find anything about artificial UV light.

Any ideas?

Why would they're be any difference between natural and artificial? All that matters is the wavelength.

All lume paint are subject to degradation due to UV light. The question is how fast it degrades which is based on the quality of the lume paint.

No matter how good the lume, it will degrade some day. The factors which affects the degradation is surrounding heat, humidity and exposure to UV and direct heat such as sunlight.

Thanks for the replies.

My interest stems for the fact that artificial UV light can be more intense than natural UV. Since degradation of the paint is due to the level and tenure of energy absorption (plus other external factors such as humidity etc), it is logical to assume that exposure to artificial UV could be worst off as compared to natural UV.

It can be said so as artificial UV has a high energy content. Hence it causes greater chemical reactions in the lume paint, inadvertently causing degradation.

I have artificial UV in my lab. Don't mind testing it if there's a volunteer.. Hehe

I am not sure if intense heat can result in that degradation. I had to send back for claim again cos it's too shoddy job by the manufacturer.

I think intense heat could contribute towards a speedier degradation.

I think the Citizen Eco-Drive manual could have the answer you want. From my understanding, natural sunlight UV is far more intense than indoor normal lighting.
