I am planning on testing my recently serviced 16mm Arri-SB and Bolex Rex4 after a 20+ year hiatus from film school. With all the wonderful lighting options using LED, I was wondering if I should rather invest in a Fresnel lighting kit to light with these vintage cameras. Would I be better off working with LED or are there serious concerns I should be aware of if I wanted to incorporate LED lights into my 16mm film shoot. I honestly can't find any substantive information about this on the web.
