Here are some LED lights that I made for wildlife coverage. BBC2’s The Burrowers needed a complete lighting set for the three underground sets they had built for rabbits, badgers and water voles. They needed to bright but very small and produce no heat. And they needed to be individually dimmed remotely. Each LED was on a flexible gooseneck and could be fitted with a range of lenses. Just like real lights! And they needed a proper lighting desk.
Springwatch needed some lights as well but they had to run on 12V batteries. I also made some infra red lights for a beaver lodge.
