Yes, I (iodine) is a halogen.
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.
Halogen is the family of salt producing elements.
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.
BR stands for Bulk Reflector, that are traditionally for incandescent reflector lamps, not halogen Par lamps, which mean Parabolic Aluminized Reflector.
Iodine is a halogen element. Fluorite is a mineral, not a halogen. Gypsum is a mineral, not a halogen. Galena is a mineral, not a halogen.
Any element, other than a halogen is - by definition - not a halogen and so it does not have a halogen and that is less than one halogen.

This halogen is astatine.
