The light you have in your pix is a MH light.You look at the lable it says 400W MH and a few other numbers.Those light are sealed weather tied for out doors.If you put it in a small space you are going to have big heat problems.In a full size wardrow cab you will have to air cool the light.My cab is a full size 50" wide 76" tall and 27" deep with 400w kooltube and it gets 78-82 in there and it's air cool light.You can put a glass shield between the light and the grow and exhaust the air from the light and you would cut down the heat. PEACE
