Halogen light bulbs are also "gas filled capsules". =)
The main difference is that in a standard bulb, the light is emitted from a tungsten filament. In a metal halide aka HID bulbs the light is emitted from an arc.
It's illegal to install HIDs in your Civic (if you care about legality). Most cheaper kits are crap because they use the stock headlights (designed precisely for a filament bulb) to disperse the light from a xenon arc. Lots of throwaway light and glare. I'm sure there are good kits out there.
