Can anyone recommend an affordable strip box, preferably with a recessed face for some light spill control, that is LONGER than the PCB one? The PCB one is only 3 feet long. I will use two strip boxes pointed towards each other for some rim lighting on a full length person and also to blow out the white backdrop. Something affordable so...something other than a Chimera or something. I have their 3x4' softbox, but don't want to spend as much for the strip boxes.
