If you're asking how well the aftermarket "clear" and "black" lights output light compared to the stock lights, it varies with the particular light. Some members have found good lights that work well, others have been dissappointed with the build quality and light output of their aftermaket beams. Best bet is to search this forum and find which lights to get for your particular ride. The "clear" reflectors do reflect less light than the stock amber reflectors since they usually don't meet any specs or standards for reflectivity or safety.
Projector fogs vary the same as headlights, some projectors are very good, most, especially the cheap brands, are rather poor when it comes to beam pattern and output. Again, search the forum and find members who found which projector fogs worked out well. If you want a recommendation, the Hella Micro DE fog lights are some of the best fogs in a super compact size. They also made a HID version.
Projectors are not HID. HID is a particular kind of lighting system, a projector is a type of lens. There are HID systems that use projector lenses, but there are also standard halogen lamps that use projector lenses, and HID systems that use other types of lenses and reflectors.
