gas
argon is used in lamps
I think for creating flashlight The gas used in fluorescent lamps is argon. Neon is used for red lamps.
xenon
Xenon is primarily used in lighting, such as in high-intensity lamps and flash lamps. It is also used in certain types of medical imaging equipment, such as xenon gas detectors in computed tomography (CT) scanners. Additionally, xenon is used in specialized research applications and in certain types of laser technology.
There are two types of lamps the tungsten halogen lamps and incandescent lamps. Tungsten Halogen Lamps are similar to incandescent lamps and produce light in the same manner from a tungsten filament; however the bulb contains a halogen gas (bromine or iodine) which is active in controlling tungsten evaporation, whereas the incandescent lamp suppresses tungsten evaporation.
there was no electircity but there were gas lamps
Fire in various forms. Candles, oil lamps, gas lamps, etc.
Gas is used in lamps for illumination by being burned to produce a flame that emits light. The gas is typically mixed with air and ignited, creating a controlled combustion process that generates heat and light. This light is then used to illuminate the surroundings.
Before electrical energy, heating and lighting were achieved using fire, candles, oil lamps, and gas lamps. Fireplaces, wood-burning stoves, and oil lamps provided heat, while candles and gas lamps were used for lighting.
That'd be Halogen.
Yes, gas & kerosene lamps were used exclusively before the invention of electricity.
