The Interviewer Light attaches to your Interviewer Light Clamp at the top of your Watch Box, and holds your Interviewer Light Bulb. If you are not conducting an in-person interview, then you can leave this light turned off during a shoot. But when you do have a live interview (between two people in the same room) you’ll definitely appreciate the extra light on the interviewer’s face. The small increase in light creates a much better reflection inside your Watch Box.
