Stealth - radar project

Hi. I'm doing the stealth radar science project. I'm not sure what to do as the control group. Please advise, thanks!
The purpose of a control group is to make sure the independent variable is the only variable affecting the outcome of the experiment. For this experiment, the control group would be shining the flashlight into the box with nothing inside it and measuring the lux meter value then (which should be zero).
