The Weltool LF61 is a diffusing filter for the Weltool W4 LEP light, as well as other torches with a head diameter of 60.5mm. 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.
