Convoy S21G Copper Head 21700 Flashlight

Material: titanium alloy body, copper head Lens type: ar-coated glass lens Reflector: made of aluminium alloy, the reflective surface is vacuum-coated Driver: 8a 12groups buck smooth for SFT40 orange peel for 519A, B35AM , XHP50.3 HI LED MCPCB: made of copper. DTP thermally conductive structure. 3.0 W/(m·K) thermal grease below the MCPCB. Head structure: integrated type (Best structure for conducting heat, but please note that fast heat transfer does not mean fast heat dissipation, which depends on the surface area of the flashlight.) Switch: reverse type, Au-coated phosphor copper spring soldered on the PCB, it can bear max 10A current ,no need to add bypass. Tail: The edges are chamfered. The U-shaped groove makes it easy for the thumb to click the silicone button. The single-sided double rope hole makes the rope not affect the handstand of the flashlight. Electro&optical parameters Driver output: 3V 8A buck for SFT40 3V 6A linear for 519A 6V 2.4A boost for B35AM 6V 3A boost for XHP50.3 HI Driver efficiency: 85%-95% Mode: See below for details Related features Low voltage warning: Yes Reverse polarity protection: Yes Mode memory: Yes Temperature control function: Yes , As the temperature rises, the current will drop slowly, but this does not mean that the surface of the flashlight will not heat up.
