Never heard of cool lights ( I am in the UK ) but I always use studio flash with modelling lights.
I use a Nikon D100 which doesnt have a sync socket so to over come that I use a small on camera flash set really low and bounced off the ceiling to fire the flashes.
You can check out the results in my gallery,its all glamour so if that offends you dont go there.
Mail me if you want to ask any questions
