Halogen light bulbs are what has been around for a very long time. Incandescent bulbs are new and are more energy efficient.
Halogen bulbs come in various ratings, as do all bulbs.
tungsten
Inside a tungsten-halogen bulb, electrons flow through a tungsten filament. The filament heats up and emits light.
Argon(or nitrogen) and tungsten are used in incandescent light bulbs.
yes, incandescent bulbs do not contain a filament of platinum. Yes they do contain a filament called a tungsten.
Tungsten in the filament of incandescent lightbulb.
"Halogen bulbs have a longer life and better illumination than incandescent bulbs. They are compact in size, and dimmable unlike flourescent bulbs. Halogen IR (infrared) bulbs use less electricity, also."
Generally, tungsten.
not all incandescent lamps (bulbs) can be replaced by fluorescent lamps because there are some applications where there is no acceptable or equivalent fluorescent lamp. In some cases, other technologies may be useful--HID or LED lamps. There are some applications where the incandescent source, especially the tungsten-halogen type, still rules.
Incandescent light bulbs. Generally high temperature, or high wear applications.
Halogen bulbs are about 30% more efficient so a 70 watt halogen does the job.
