are all 6 interior sides padded, (top, bottom, sides and ends)? Is it enough padding to safely put in 3 or 4 studio lights?
Bottom and all four sides are thickly padded. The zippered top is lightly padded (probably to allow for flexibility), but in addition, there is a separate pad which fits on top of the lights before the top is even closed. So, in effect, the top has padding equal to the bottom and four sides. The three (thickly) padded partitions allow for the bag to easily carry four studio lights, The only shortcoming I find is that I would like to see velcro strips on the bottom pad to allow the partitions to be attached to the bottom pad as well as the top. Overall, great bag for the money. Good luck.
