supfire... We don't call it divine fire, but mountain fire, which is short for imitative divine fire. A true foolproof, Surefire's cheapest G series costs over 300 yuan. Nowadays, the main brightness of bright flashlights is 1000 lumens, and the foolproof 1000 lumens costs no less than a thousand yuan, and it uses expensive CR123A batteries, which are the cheapest. Single-cell batteries cost 10 yuan and are not rechargeable. A 1,000 lumen model requires three or more cycles at a time, and a well-known domestic brand of the same level costs about 400 yuan.
