Hello Shane, I’m a bit confused. Once you settle on what gels you need to reach the 5600K target – do you label the lights with the target temperature and what gels are needed to reach this target? or do you label them with the existing temperature and what gels are needed to reach the 5600K mark?

Thanks for this episode! Never thought HMI could be that “unperfect” color wize. Do you leave the gaffer tape label on the unit when it’s on? Isn’t it going to melt/burn once it’s turned on?

      @Jeanto Hi Jeanto, The gaffer tape won't melt down on the bottom of the head where we placed it. Yes, it all depends on the rental house.
