Talk:Incandescent light bulb

message: The phrase: lava lamps, and the Easy-Bake Oven toy is in a sentence describing infra-red lamps, which are usually ones designed for heating use, often with red colored filters. Those applications use ordinary lamps for their heat (IR) output, not ones intended for heat output. Gah4 (talk) 19:59, 27 November 2019 (UTC)
replies: text: Heat lamps are specially designed with a glass such as quartz that has fairly good transmittance to IR wavelengths, and are operated with low enough current per the filament so as not to produce white light.  but more of an orange/reddish glow. Both lava lamps and Easy Bake ovens use standard bulbs with glass that has poor transmittance to IR. (See two sections above for more on glass transmittance.) Instead these transfer heat mainly due to convection of the air around the bulb, directly heating the air due to contact with the hot glass, which can typically reach temperatures of around 350 F. The Easy Bake actually cooks with convection much like a normal oven, and lava lamps also not only transfer heat from convection, but make that convection visible in the movement of the liquid.

message: actually, tomas edison didn't invent the lightbulb, he just inproved it. He bought the patent for it from two Canadian inventors, Mathew evans and henry woodward. 207.228.78.204 (talk) 23:06, 9 March 2020 (UTC)

message: i can only give as reference a link to the german wiki : "Als elektrischer Isolatorlack auf Wicklungen und als Kitt, der das Glühlampenglas mit dem Metallgewinde verbindet, ist er wegen der gleichen Wärmeausdehnung noch im Einsatz." see under "gegenwärtige Anwendungen" Schellack - wiki--Konfressor (talk) 08:27, 24 February 2021 (UTC)
replies: text: Well, that's very likely so, but this is more relevant to copper wire or magnet wire, or even the shellac article than it really is for this one. That they use magnet wire to connect the electrode-stems, protruding from the bulb, to the threaded cap is no mystery. Magnet wire is ideal in most any situation where you need an extremely thin insulator with good dielectric breakdown resistance, and temperatures that may exceed the melting point of most plastics. It seems like a bit too much detail for this article, which is already over-sized. We're not an instruction manual on how to build them. Note that this does not refer to the seal between the glass and electrodes, which is done by welding to create a hermetic seal. Shellacs and glues emit volatile organic compounds (VOCs) that have a tendency to fill any vacuum, plus they burn up during the vacuuming process when the glass is heated to red-hot to purge any oxygen or water vapor clinging to the glass via adsorption. This only refers to the wires connecting the threaded cap. (Not to mention that Wikipedia is not a reliable source, so you'd need a better one.) Zaereth (talk) 08:59, 24 February 2021 (UTC)

message: GLS light bulbs redirects here. Perhaps it should say what that means... (Also: I got here trying to find out what GLS means from a listing of an LED GLS bulb, so incandescent-only is probably wrong.) 86.26.33.25 (talk) 18:30, 14 January 2024 (UTC)
replies: text: Fixed. GLS light bulb now redirects to , which now mentions "GLS".--Srleffler (talk) 20:02, 14 January 2024 (UTC)
