Halogen is a gas, so your question doesn't make much sense. If you're asking about a halogen (light) bulb, then the answer is: mainly halogen.
Halogen gas is in a Tungsten-Halogen Light Bulb.
The halogen element used in halogen lights is typically iodine or bromine. These halogens help to increase the efficacy and lifespan of the light bulb by allowing the filament to burn hotter without deteriorating as quickly.
A 230 watt linear halogen lamp should be replaced by a 230 watt linear halogen lamp if the same brightness is required.
As 'I' if you mean 'iodine' , then yes!!! it is a halogen. The halogen elements, by name are, Fluorine(F), Chlorine(Cl), Bromine(Br), Iodine(I), Astatine(At), and Tennessine(Tn). The last two being radio-active and not fully characterised. The word' Halogen' from its Latin roots , means 'Salt maker**/gen**erator'.
Pseudo means "Fake"
iodine
The different types of halogen bulbs available in the market include standard halogen bulbs, halogen floodlights, halogen spotlights, and halogen capsule bulbs.
