Got some very interesting lamps recently. Look at the spectrum. Guess the light source.

Spectrum from VU1's ESL cathodoluminescent lamp? If that's correct, then its really nice that you manage to get one; I don't expect these lamps to survive very long on the market...

Yup its the VU1, I like to call it the TV bulb because it is nothing other than a CRT made as a light source! Behaves like a CRT all the way.

@Max, I owe you an email lol. Sorry for the delay, I've been scatterbrained lately with stuff going on. Will do later tonight.

May all the great lighting technologies have their place in history.

It looks like the lamp contains the same phosphors of color CRT computer displays and TVs(I don't know about the phosphors of plasma TVs).
I've have seen how the white color on CRT display looks, and it don't looks like it have a good quality for lighting.

I"m don't speak English well, and rely on online translating to write in this site.
Please forgive me if my choice of my words looks like offensive, while that isn't my intention.

I only working with the European date format (dd.mm.yyyy).

I lives in Israel, which is a 230-240V, 50hz country.

This has a different phosphor than a CRT display. It's warm white in color.

The emission in the green, don't looks like terbium. CRT displays also had lines in the red and orange, than a continuous from the green to the blue.
Triphosphors fluorescent lamps, have also a terbium green line, which is missing here. And I expect that this lamp would use triphosphors, for high efficiency and color rendering (Despite it can use halophosphors and deluxe white phosphors as well).

The light color is just aboutthe ratio of the components, sono reason why standard CRT phosphors should not be sufficient for that.

@Dor: Here the phosphors are excited directly by electrons and not by UV, so the base material for the phosphors here are different than those in fluorescent discharges (and e.g plasma TV's - with that the plasma TV's are more related to fluorescent lampss than CRT's). I'm not sure, if halophosphors could be excited justby electrons, or how efficient they would be.
However the phosphor dopants (the part steering the color of the emited light; used in minute quantities) could be the same.

No more selfballasted c***

@Dave - OK, thanks a lot!
About the ESL lamp, do you find that it accumulates quite some static charges when in operation? When I bring my hand close to my lamp, I can hear many static discharges...
