Title: Type and amount of UV emmision needed to cause a mercury lamp to glow pink
Post by: HomeBrewLamps on January 14, 2019, 07:05:29 AM
What amount of UV and what type is needed to perform such a task.... At some point in the future I would like to get a hold of a burnt out BT shaped mercury Lamp, cut it open at the neck and  put in some sort of UV emmision source that would make it constantly glow that wonderful pink color... Would a germicidal or UV LED lamp work? After building a new internal structure I would like to reseal the lamp with whatever new source is in the there... So it'd look "authentic" aside from the intern construction...

A germicidal fluorescent would work best.

Do I miss something or is this some de-ja-vu? I'm convinced this was already somewhere answered by either Max or James (I don't remember anymore who exactly), pointing to even any blacklight (fluoro or even LED) as a sufficient exciter, but recommended to better use a new MV lamp as a starting material for this, to have the phosphor fresh...

My point: I would try to not use any dangerous UV, first to not have problems with ozone (not only for health as you expect it to be sealed, but as well to avoid glue and other internal parts degradation), second to not have problems with dangerous UV spill (your assembly wont be by far as perfect as the original). So better stick with some of the blacklight, these are safe, both for you, as well as for the plastic components you will have to put inside.

I'm unsure but thankyou for the replies guys. I don't know when I will do this.... I need to get my hands on a diamond saw and some way to bond glass back together, but I will use this as a reference.
