Summary

Despite its slim head, the new Sofirn SR12 is a real thrower – the deep reflector and the Luminus SFT-25R make it possible. With a length of only 112 mm and a diameter of about 24 mm, it should still fit easily into your pocket, making it perfect as an EDC flashlight. It becomes even more interesting when combined with an optional short battery tube for 18350 batteries, which reduces its length to 79 mm.
