What about magtac64 2-cell CR123 LED flashlight?
The battery has a great influence on selection of battery flashlight brightness and battery life, lithium battery can be used repeatedly, and has the characteristics of high capacity, the overall life is longer, and largely saves the cost, but not easy to buy a single, short life, dry batteries can better play the big power LED effect, high stability, and single use time is long, and easy to buy, but the batteries need to be replaced, the cost increase, foreign people generally love battery, domestic friends mostly choose lithium battery. This is the parameter of CREE LED, more than this is generally virtual standard.
Cylinder material: aluminum alloy with more common cylinder, besides stainless steel and titanium alloy. Stainless steel stress, titanium alloy price is expensive, aluminum alloy is relatively moderate, widely used.The difference between the performance of different aluminum, can also cause a large price gap, multi brand flashlight using aircraft grade Aluminum Alloy T7075 T6061, the highest level, this material is super corrosion resistance, impact resistance, and easy machining, flashlight made of this material, appearance is very delicate, deep clear thread sealing performance is very good, the handle is also very good, is currently the best product, but the price is a little expensive! The tube body processing, aluminum alloy surface oxidation rule has a direct impact on electric price.
Optical glass: according to the requirements, the widespread use of two kinds of light cup, smooth metal reflector, the light is very concentrated, can through the light reflecting cup more perfect spot, suitable for long distance lighting, environment, hunting and exploration; orange peel metal reflector floodlight effect, diffuse reflectance clearance, irradiation a wide range of clear for close range illumination.
LED flashlight with high-power single or multiple [and] the light emitting diode as the light source, widely used Aluminum Alloy as barrel material, with 26650 and 18650 rechargeable lithium batteries and Cr123, C, AA, AAA alkaline dry battery provides power, connected with the microcomputer chip or circuit board efficiently. A super bright lighting tool!
