Soonfire D01 Diving Flashlight: CREE XM-L2 U2 LED, 900 Lumens, 100m Diving Depth, Magnetron Switch, Exrernal Layer of PA66 and Internal Aluminum-alloy Intergrated Molding, 18650 Rechargeable Battery Using US CREE XM-L2 U2 LED, the highest lumens to 900 lumens, LED life of over 100,000 hours. Use 18650 rechargeable lithium-ion battery, last longer Flashlight innovative use PA66 (seabed Cable Material) coverage the surface of flashlight, aluminum-alloy cores to improve itself compressive strength, PA66 improve the bending strength, which is the perfect combination of rigidity and toughness, so that comprehensive mechanical properties of the flashlight is best Use aluminum vacuum plating glossy reflective cup, significantly enhance the concentrating affect, the spot is perfect. Reflective cup surface plating layer, high temperature resistance, hard fall down, lasting as new High strength and toughness and high light transmittance glass lens, it has a better deepwater compression capability, overall after pressure detection, can Diving 100 meters Hand-push magnetic switches, wireless control, safe and easy to use. Tail junction, using thick double rings, waterproof performance is more stable
