I have to say very clever job. Simply but looks to me will do the job perfectly. Like the idea about a dimmer switch. I use white paper front of the lamp if I want dim light or just pull the lights a bit away from a tent. This is probably just my way of thinking, I find a box a bit small. Just incase you planning to capture something bigger object the box /space might be a bit thight.  Exsample, vase full of flower with a fruit bowl, dinner plate with a glass of vine. This is an observation not a critique. So I guess we will see many great still life shot in your gallery. I am curious for sure.
