Fluorine, at 19 atomic mass units, is the only halogen gas that fits that requirement.
They usually require less power, but you can get a very small bulb that will run less power. All in all though, halogen is the least efficient when it comes to heat, power, and amount of lumens (light) it projects.

Francium. Oh, and you spell it 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.

No, It is a little bit (0.1) less than an ounce.
1 gram = 0.0352739619 ounces This holds true on Earth. On the moon 1 gram = .00587 ounces. On Jupiter 1 gram = about .082 ounces. Overall a gram is a great deal less than one ounce.
no
no. one ounce is bigger than a gram (1 ounce = 28 ounce)
No problem because the 200 watt produces less heat.
