forget cool temperature - go for tungsten if you don´t have to combine it with daylight. the cold light is so ugly to look at. same for hmi. i have some old foba fresnel spots 250 / 500 w, some hedler 2000 w and 4 dedo lights. the dedo lights are a dream to work with. on their web site you will find some special reports about their lights mostly from film people, very nice to read.
remember that it is not only the light producing that kind of look. an old/not perfect lens would do you also favour. realy cool are old enlarger lenses, you can get them cheap. i adapt them with the zoerk multi focus or the linos rodenstock adapter.
have fun :-)
