@@Dilophi helps keep the oxygen off the carbon rods to extend the runtime.

@@Mirroxaphene Thanks for the answer, now it makes sense. It probably saturates itself with CO2 until there is not much free oxygen left which acts like a an early form of inert gas filling, i guess.

@@Dilophi that’s exactly what it does.

@@adamsaintgermain4149 do you have any pictures? Where did it come from?

@@craigrryan86 not much. They aren’t very bright. Probably equal to a 100-175W mercury lamp.

@@heartland96a 150-175 hours for one trim. Most lighting companies had dusk until 12A service for arc lamps

@@Mirroxaphene interesting details

@@praestant8 it’s a crunchy snack :-P

The single contact ended fluorescent lamp you described is widely known as a slimline fluorescent, introduced in 1946 by Westinghouse, the very first ones were indeed slimmer - F42T6, F64T6, F72T8 & F96T8, as opposed to the then most widely used lamps, the F40T12 48 inch, and F100T17 60 inch - introduced in 1940 as highest output fluorescent lamp at the time mostly used in manufacturing facilities and often considered an early prototype of the High Output, Very High Output & Powergroove lamps later introduced by GE in the mid 1950s. Soon after westinghouse introduced the slimline lamps, T12 single pin lamps became available but the name stuck. Today slimline lamps are available in T6, (F42T6, F64T6) T8, (F72T8, F96T8) and T12 in 24, 36, 42, 48, 60. 64, 72, 84 and 96 inches, with the F96T12 by far the most common, along with the F72T12, with the 48 inch and smaller being very uncommon. Slimline lamps are also referred to as instant start lamps, they require a significantly higher voltage to start than other lamps of a given length & diameter, therefore special ballasts are required. Because the lamps start don't use cathode heating like a bi-pin lamp, slimlines are slightly more energy efficient although lamp life is somewhat reduced for a given number of hours/start, so they were almost always used in commercial settings where the lamps are expected to operate continuously for several hours or days between starts.

@@Sparky-ww5re thanks😀

@@douro20 I’m thinking yes.

IKR! they are just throwing it away, anyway. I love to dumpster dive for electronics, for repair or parts.

Could be a hazardous material dumpster intended for special handling disposal. Or, the company just has a policy against it so that employees don't throw away useful items with the specific intent of collecting it later.

No It has to be accounted for, as it sold as scrap metal.

@@Muonium1 majority of the electrical contractors are crazy about people taking their scrap material. It’s a liability thing.

​@@Mirroxaphene i mean is it illegal to get something from the dumpster? (Sorry im not from the US so I don't know any laws about it over there)

​@@nathanwyson3232generally, no, so long as you are not trespassing to access the dumpster. At least in my locality, removing something from a construction waste dumpster accessible from the sidewalk (e.g. parked in the street) would be perfectly fine.

@@Mirroxaphene i thinks its just plain greed! the want the weight for the metal all to themselves... and get their shorts in a knot if someone takes any of it from them.
