hso called it, Surefires mostly. They seem to have a flashlight of the day/show. Saw on a behind the scenes show, that they get alot of they're stuff free as product placement.
When looking for small items, it is better to leave the lights off and use a narrow beam light to look in one spot and move on in a pattern till area is cleared. I hope they have rechargable lights, because I'd hate to be buying the batteries they go through.
