Sorry for the delayed reply, but yes, I intentionally wanted it darker (although I did this by darkening the area around him in post). I think itd work for your situation. If possible Id try to have a fast lens with you just in case. I have the spot version of the light so depending on if you get the flood version (25 degree vs 75 degree beam) maybe your results will differ? You may still be able to get the effect you want with the spot version too, if you want the light more focused on him. In my short film, for the singles of the guy in blue light, the light was about 10-15 feet away and about 12 feet high. I THINK I was shooting roughly at about F2 (maybe higher), SS 1/50, and ISO 400. I also decreased the exposure more in post too. Im going to GUESS it will work for your needs, it would really just depend on how wide the shots will be and the settings you are shooting at.
