I have struggled to find the right LED on-camera light for the canon 7d and the canon 5d. the original one I purchased had trouble with pulsing that would show up on camera in lighted subjects. THat was the Bescor .
BESCOR 50W since discontinued.
here is the music video I shot on the 7d with these discontinued lights.

pretty shitty! i used a few of them to light the interior of a car at night.
so now I’m trying out the new one and it doesnt seem to have a pulse. we’ll see.
BESCOR 60W LED
Also on this project I used the Varizoom Car Mount which i thought was a waste of money when i bought it as I was shooting with a Sony EX-1.and the Sony was just to heavy for it. so it spent most of the time in the closet….until I got a Canon DSLR. now i love it! its perfect!
