FS-44 Thermal Starters for 40w Lamps

FS-44 Thermal Starters for 40w Lamps

Click to view full size image

I got these four starters off of eBay a while back. These were offered to start 40w lamps down to 0 F. Wether or not modern low mercury lamps will actually allow these to perform the task they were designed for is the question. I believe these came out at around the same time the two pin glow starter did (1939), but I am not certain. I know the y were available by 1942 from my fluorescent lighting manual.

These were not popular at all to my knowledge. I’ve never seen or even heard of a fixture that used them. They have are the same size and posses the same base as starters for T17 lamps, which probably explains why they weren’t used much. Their only real advantage, besides ideal lamp starting conditions, was their cold temperature performance, which was a moot point with the introduction of the low temperature F40T12 lamp. I do wonder how the performance of thermal starters with the low temperature lamps would be, but I’ll probable never find out, since the low temperature lamps were discontinued around the late 1950s with the advent and growth in popularity of the high output lamp.

These will be used when I finish making new socket brackets for my Benjamin Electric light fixture, which will accommodate the larger starter hole and socket.

Nice!

Don't be fooLED, T8 IS the worst thing to do to a magnetic T12 fixture.
