just wondering i bought a 120vac halogen lamp(no transformer) do these
bulbs typically put out 'rf' that would interfere w/either my hf rig or
my hf/uhf??


No RF problems. Halogen lamps have tungsten filaments (like normal
incandescent lamps).
The difference is that they are filled with halogen gas, which allows them
to last longer and glow a bit brighter than their normal incandescent
cousins.
The tungsten in regular lamps slowly condenses over time into a darkish
coating inside the bulb which cuts down on lumens output. The halogen gas
prevents this, and results in a little brighter lamp for a little longer
time.

The 'HID' High Intensity Discharge lamps may be the ones you're thinking
about that may give some RFI.
Mercury Vapor, Metal Halide, and 'HPS' (High Pressure Sodium) lamps fall in
this category. They all use ballasts.
