Very bright blue LED... Makes the liquids in the eyes haze up... Also hard to take a photograph of lol. Ironically harder than an actual Black light LED.

Are these blue or deep blue LEDs? Blue LEDs are also hard to my eyes.

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.

Blue light from LEDs, is way worse than blue light from fluorescents and MH.

I means when compared to fluorescent lamps and MH for color washing and decorative applications. The T17/SPB/VHO deep blue fluorescent lamps, are for medical purposes such as jaundice treatment.

Okay, I was comparing to it and blue LEDS is worst...glad I don't buy it. I have GE LED bulb reveal (2850K) and it's better than CFL, I have one in my room and it's been a year.

Blue and deep blue LEDs, don't produces UV, but still causes fluorescence on on fluorescent things and attracts insects and yellowing plastics.

I don’t believe the T17/SPB/VHO was for medical purposes. It was used in whiteprint machines that created prints via the diazo method, hence the color being called “Super Diazo Blue” by GE. The prints were basically the reverse of a blueprint, and needed the UV exposure in order to make the image appear. Further UV exposure, such as being out in the sun, would cause the image to disappear in a few days, so they were replaced as soon as large xerox machines became practical. The machines also required venting of the printing room due to the ammonia produced in the process.

The price for those tubes are insane!! Us there 6 members out there willing to each pitch in 200 something dollars for a case of twelve lamps!? I seriously doubt even that.... They're more expensive than SOX!

I have a pair of similar FR48T12/350BL/VHO/180 lamps. They're 4' 350 Blacklight VHO reflector lamps. Insanely bright when run on a VHO ballast. I'm pretty sure they're intended for a printing machine.
