Hello, I am asking about "cool lights" for a project I have boiling over on the back burner. I have heard about "cool lights" in the film industry. They are supposedly very cool... not hot. Even 50K lights used at night, to make it look like daylight, can be cool lights. The conventional ones are very hot. (Actually, the grips and lighting technicians prefer the hot lights simply because they have become used to handling them cautiously to avoid being burnt... out of habit) But, what I am after is a very strong (50K to 200K) light that remains cool. I wonder if anyone has a link or an article pertaining to such a light or "cool light". Thank you.
