CHICAGO MINIATURE NE-42 3.5 WATT

CHICAGO MINIATURE NE-42 3.5 WATT

Click to view full size image

This is a recent ebay score. As some of you may know I love negative discharge lamps. This is a epic little lamp emitting that wonderful neon glow.

I'm operating this lamp off a 2.7 kilo-ohm ballast resistor (Red, Violet, Red) instead of the recommended 2.2 kilo-ohm (Red, Red, red) due to lack of 2.2 kilo-ohm resistors in easy reach.

Is this lamp manufactured by general electric? What does CM mean??? When would this have been made and where? Reason I ask is because the general electric meatball is not in the etch... It is simply "CM".

Awesome find!! Weird how they fitted an b15 double contact bayonet base to an S14 bulb envelope, had seen similar bulbs listed on Etsy as well.

Long live the great old 20th century quality in electrical & lighting products!

I actually got this one from etsy but my phone autocorrected etsy to ebay lol.

I find it odd too... I only have one socket that can take this bulb! I reckon it is because they didn't want someone screwing it into a mains socket and having it explode lol.

That may sound about right there or else!

I’ve seen these ones without resistors used as voltage references or as elements in oscillators in old tube based equipment.

Here’s a power supply that used one (Skip to about 6:30 to see the tubes and the bulb being installed):

Nice!

Good quality things are awesome. Cheaply made things are not.

I understand the reason for the SBC not common in America was as some have said to prevent the lamp being plugged into normal 120v which would cause the lamp to explode, these were I think used for voltage regulation in old radios. Always take care with the American neons some show a voltage when are regulators.....take extreme care and if doubts use variac AND Resistor. Look out for the Argon glow lamps loverly glow

Argon glow lamp is next on my list to get.... I'd also like to get a helium lamp and a beehive lamp

(and perhaps some spares of each)
