Interesting lamp!

I used to work at the local newspaper. I don't really know much about the plate equipment, but the lights in the plate room always had gold tubes in them.

This lamp isn't a blacklight lamp at all (Because it don't designed to make fluorescence effects), but an actinic UV lamp for offset plates and silk screen plates radiating.
We usually use UV MH lamps that have halides of iron-cobalt or lead-gallium for this application, because they are much more compact and efficient.

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.

@dor123, these ARE indeed blacklight lamps in USA, but they are unfiltered. They make things "glow" like the BLBs do, but they do not filter out the visible light like BLBs do. I have several BLs and BLBs in my collection. My bug zappers all use one each of BL and BLB.
This VHO is an unusual one though! Would love to see this lit!

As DieselNut mentions, this is a 'unfiltered' Blacklight .. I've got the 40w version of this lamp & they will make fluorescent-colored things 'glow'.

But dor123 is also correct in that it is an actinic lamp (known as: Actinic-05 ... where the standard aquarium actinic is: Actinic-03 (and a much deeper/brighter blue))

The 40w version is dim (but sorta hard on the eyes in that way that blacklights are) I'd love to fire up the VHO version on my ballast & compare LOL

You should deff be able to run this on your HO ballast (even a normal F40 ballast will light it...at 40 watts)

That is one neat & rare fluorescent bulb !!!! My guess when lit it produces a color close to those fluorescents used in a tanning bed.

Looks like this one has "350" etch on the bulb. I guess this one is for 350 nm peak output.

Comments?

Pretty, please no more Chinese failure.
