In the film & studio lighting section (Pg. 184 in my edition) there is a listing for a lighting instrument called a "cone light". It says it is available in 1k and 2k sizes. Now I ask you, what is a cone light? Is it an instrument with a conical reflector, a conical hood or just a conical beam spread? I'm usually aware of my fixture types, but this one's got me. Might anyone have a picture?
