I am very curious as to exactly what kind of gas mixture is used in these really tiny little green bulbs, but it ain't no neon! Or ain't it? Well, not entirely. Enjoy!

These neons come in orange, green and blue. They've been around for over 40 years.
i think they were sold at radio shack way back i remember seeing. these as a kid and had fun with them, maybe it was another store forgot. but they were cool
De gas otros naranjas son de leña
LED to replace neon indicator bulb? There is a manufacturer that produces red LED that can directly replace neon, even no resistor is needed when it is connected to 230VAC. LED is flat (size about 4x6x0.5mm) and it has two active spots, maybe there are two diodes connected in parallel. It could be COB type of LED. I do not know what is manufacturer (no label on LED) and I do not know where to buy these. Anyway, I have 3 samples those I get when I ordered 10 power switches from AliExpress. 7 of these switches had classic neon bulb with a resistor and 3 had this innovative LED to replace neon bulb in voltage indicators… I needed a neon indicator so I opened one of those power switches "with red light" and I was surprised that there was part that look like a flat LED and I like this mysterious part but I do not know where to buy more…
It's like the ne-2
I was surprised to find one like those as the power indicator for a Commodore 1702 monitor. I always thought it was an LED, but a green bulb!
une led au ✨mercure✨ et avec du ✨phosphore✨
The green bulbs were used in many clock radios. I just ordered some.
The glass UV filtering? Richard Feynman said he watched an A-bomb test from behind a truck's windshield, so I guess some glass will do that (but I still wouldn't try it).
Fkn Kyle ritenhouse adverts. Seriously YouTube?
I have some of those from the old Radio Shack (RIP). Could the UV absence be because the glass is too thick?
Great video, thanks!
BTW, here's a fun fact: these old soviet ИНС-1 neons are not russian, they are ukrainian 🙂
Note the logo on the box (a circle with a dot inside) – it's 'Gazotron' plant located in the city of Rivne, Ukraine. They made neon lamps, vacuum fluorescent displays, some Nixie tubes and helium-neon lasers like ЛГ-79.
Actually, i have some big neon glow lamps which have a phosphor coating. It glows green, but you can clearly see an orange spiral on the inside
I don’t know ! But there’s something about neon which is beautiful
Nice 👍👀
1945 US patent 2,421,571 by W.E. Layson covers the Neon-Krypton Mix. US 3,536,945, to C.D. Skirvin covers the rest of the details. Neon by itself emits miniscule UV. Other phosphors are driven by electron impact with a mix containing Xenon.
Except some of them use Xenon-Neon or Krypton-Neon excimer mixtures to produce 176 nm UV for the phosphor. Without a spectroscope, you cannot be sure. Many have NO mercury at all.
