Blacklight entry in Wikipedia needs serious update for UV-LED section

[Andrea B.]

Anybody out there who does some Wikipedia work?

 

The Blacklight page needs a big update for the LED section. There is exactly *one* sentence and that is inaccurate as you will note.

 

Ultraviolet light can be generated by some

light-emitting diodes

, but wavelengths below 380 nm are uncommon and the emission peaks are broad, so only the very lowest energy UV

photons

are emitted, within predominant not visible light.

 

Currently I don't have time to update this myself.

I agree. I remember seeing that section before and thinking it needed a major update.

That's only about 12 years out of date. Just like reading Britanic encyclopedia in the library.

The common black light I have emits a broad range and goes much deeper than 380nm.

Easily covers the entire UVA range according to my Sparticle.

Oh, and yes, various LED's go below 380nm, such as most of the ones we use in our UV torches are 360/365nm.

Will this be on the test?

Anybody buy incandescent black lights. I have 2, one 75W and super dimm and extremely hot. Apparently the heat helps increase UV output.

That might be what this author is thinking about.

Steve, the colors you got on the Sparticle are very pretty. You even have different shades of green, from lime to pure green.
