Cor,
I have set up the light in an alcove that is created by a dormer
window, with a curtain on the inside that I pull down during
exposure. The curtain blocks virtually all of the light from the
adjacent room. The color of the exposing light, though on the the
cool side, is visibly more white than blue. Metal halide units emit
most of their radiation in several spikes beginning at the upper,
less dangerous end of the UV zone, from about 350nm, to the blue and
green to around 500nm. The bottom line is that you want to protect
your skin and eyes from UV light as much as possible but
extraordinary precautions are not required to work safely with most
most metal halide units.
