NE-2 neon bulbs
Another thread on here mentions the NE-2 neon bulbs. I remember those
going back to the 60s. They have never changed, but worked well for testers or indicators if you did not want brightness. But I always wondered, was there a NE-1, or a NE-3? I always wondered why they are called NE-2? I have never seen any other number after the NE-. One thing about them, if they were used for continuous use, such as a nightlight. Eventually they get weak and die. They usually flicker first. I had a nightlight with one of them that eventually did no longer light, but if the room's lights were turned on, then it would light. I recall showing that goofy thing to a friend and telling him it was retarded. We got some good laughs out of that thing... |

NE-2 neon bulbs
NE-1 lamps are Edison based, 3/4" globe neon lamps commonly used as on/off indicators for radios in the 1950s and early 1960s, mostly from Zenith and mostly AM/FM. I have a sleeve of them that I got when I purchased a brown-paper-bag of *stuff* at a flea-market. Coincidentally, that bag also included two NIB RCA 7199 tubes. Go figure.
I also have a sleeve of fuse-style neon lamps. I do not remember the part number, and I did not think there was any modern application - until I looked at my 1-point tester some time later. They look like this: https://image.ec21.com/image/leboda/...mp-picture.jpg Peter Wieck Melrose Park, PA |

Like how not every band-aid is a Band-Aid. They did make some small "neon lamps" using gases other than neon, I'm pretty sure I've seen unfiltered violet and red before.

NE-2 neon bulbs
There are several €śNE-x€ť neon bulbs of varying voltage and base (or wire leads).
I just changed an NE-2 bulb in a B&K Precision 1601 Regulated DC Supply. The €śoperating life€ť of Neon bulbs is usually ~ 20,000 hours, so after about 10-15 years of continuous operation, the bulb will either flicker or €śgo dark€ť. Illuminated Rocker switches (Carling Curvette LRA 211 or 911) are used in power strips, Astron DC power supplies, and WTCPN or WTCP series soldering bases. Mouser stocks popular models, at less than $2.00 https://www.mouser.com/Carling-Techn...Zcbt5jZ1ywu5hg Digi-Key stocks most popular LRA. https://www.digikey.com/products/en?dc=20389 Since this illuminated rocker switch conforms to the standard appliance rectangular cutout, a number of other switch mfg. (Cherry, NKK, C&K, Eaton) offer equivakents. |

Neon plasma is red-orange. The depth of your ignorance never fails to amaze me. https://sciencing.com/gases-used-neon-signs-5581339.html A late reply... I'm not particularly impressed by the link information. Yes you can use other noble gasses in a "neon" sign. I don't think the other gasses are used much. Actual "neon" signs are transparent glass, and you can see the plasma discharge in the center of the tube. Almost all the other signs have argon to strike, and a small amount of mercury, which vaporizes. The mercury arc produces UV. The inside of the tubes have a phosphor for the color produced. You can not see through the tube (to what is behind it). They are cold cathode fluorescent lights. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |
