The Weltool LF61 is a diffusing filter for the Weltool W4 LEP light. The use of this filter diffuses the light, changing it from a tight spotlight to a wide floodlight. The filter protector tightly attaches to the head of the torch giving it extra protection. The filter has a spring cover design which means you can quickly open it to change between a spotlight and floodlight. Designed for the Weltool W4 but will fit other torches that have an outer diameter of 60.5mm.
