I just purchased a great lego light with a high power drop-in. I need to get a lens for the bezzel to protect the optics. I want to get a UCL lens from flashligh lens . com but I don't know the exact size requried. I see that they have a glass lens on the solarforce sight, but I don't think it is as good as the ULC. Does anyone know the exact size of the lens for that bezzel? Thanks by flashlight brothers and sisters.
