Cluson Filter Set compatible with torches from Cluson's Pro Scanner 1000 range including the ML1000. The filters slide on to the front of the torch and can be fastened using a handy thumbscrew. This filter disc can then be left in place to produce a beam of light in the desired colour or flipped up to revert back to white light. These filters are perfect for nocturnal surveys reducing disturbance created using white light.
Each filter set contains three filters in different colours: red, amber and yellow.
