Fluorescent Desk Lamp Gear

Here is this Art Specialty desk lamp with the base plate removed. Inside are two Radionic chokes, from Chicago like the fixture itself. This unit does have a tendency to buzz. The ballasts are open core, are not firmly mounted, and the entire fixture is metal, so it's not surprising. I would have liked to see some kind of mounting brackets that secure the ballasts to the posts inside the fixture, along with some padding to absorb vibration. The plate seems to be responsible for much of the humming, and it's actually nearly silent without it. Also, the ballasts don't seem to vibrate all that much on their own. Perhaps the alternating magnetic field and not mere physical contact is responsible for the vibration of the cover plate.

I'm curious if the internal design or ballasts used changed over the decades. On the outside the newer units have a single rocker-switch as a opposed to the two round button switch, have white sockets as opposed to black, and a polarized plug. The oldest have separate end plates on each side of the fixture. However, by and large they remained the same. The parent company, Ace Industries, is still in business, but I believe they quite making all Art Specialty lamps about 10 years ago.

I dont know about that specific lamp, but I have collected at least 20 of those manual preheat desk lamps, mostly 15 watters. they normally do have open core ballasts although i have a couple with small potted ballasts, and i defiantly do like them a lot better. and most of them are not secured in any way besides being stuffed inside the base. however most of the ones i have collected have a thick asbestos pad on the inside of the base plate and a thin,construction paper like sheet of asbestos rolled around the ballast for noise dampening. furthermore they normally have some form of rubber or felt feet on the bottom of the lamp on the desk. on that lamp, if the noise is to badly loud though i would get some of that scotch double sided foam tape and put it all the way around the metal casing of the ballast to try and dampen it some. also add some rubber or felt feetie thingys on it.
