W4 LEP search light throwing distance up to 2.6 kilometers 1.5 miles. Luminous flux 560 lumens, light intensity reaches 1,782,000 candela, use one 21700 rechargeable lithium ion battery (included), high-quality drive circuit with temperature control, constant current drive and ensure that the flashlight will not overheat. W4's LEP light source has high energy density, and then passes through a special lens reflection system to form a dazzling light column. High and low brightness modes are adjustable, simple and practical.

    In the off state, only half-press the switch to turn on the highlight, and it is equipped with a stainless steel bezel for tactical use. The W4 spotlight has almost no floodlight, concentrated light, and significant spotlight effect. It is suitable for field search, sea rescue, long-distance indication, etc.

Notes:

• Unauthorized disassembly may damage the light and void the warranty
• The light will increase in surface heat during use, recommended use is outdoors in a well ventilated area with ambient temperature under 25 degrees Celsius and the wind speed exceeds 5m/s.  When the light is uncomfortable to hold due to increased heat, please turn the light off until it cools down.  If used indoors, it is recommended to be used for no more than 10 minutes each time and allow the light to cool down between uses.
• Please swap out the O-rings regularly to maintain the water resistance level
• Lubricate the threads with professional grade lubricant regularly
• Maintain and keep clean any contact surfaces of the flashlight with alcohol swab.  This may prevent irregular flashes during use.  
• Remove batteries during storage.  Keep lithium-ion batteries charged approximately every 4 months
• This flashlight may not be used as a diving light
• Do not aim this light directly at eyes or exposed skin to prevent injuries
• Keep this flashlight out of the reach of children.
  
  WARNING: 
  This light uses a high efficiency LEP emitter, with power output between 0.22 – 0.25W, classified as a Type IIIb laser device.  Please use in accordance with applicable laws and regulations. By using this device, you certify you have read the included “Laser Safety” warnings and release the manufacturer and retailers from all liabilities.
  The tail cap acts as a “safety key” and must be kept safe.  The tail cap switch can shut off the light immediately or by twisting off the tail cap as a safety back-up.  An opaque protective cover can be purchased additionally.  Equipped properly, this protector will prevent any light from escaping the front of the flashlight as a safety device.
  DO NOT aim at another person.  DO NOT aim at mirrors, glasses or other reflective surfaces.  DO NOT aim at aircraft or vehicles in operation.
