The Weltool W4 utilizes LEP (Laser Excited Phosphor) technology. It emits high-intensity light with a wavelength range of 400-700nm. The output power is between 0.22 – 0.25W, resulting in a bright 6500K white light. 

The light beam is highly concentrated, without any light spill. It can focus on small objects even at a distance of up to 2,670 meters in High Mode, providing 560 lumens and an impressive 1,782,000 candela of light intensity.

The Weltool W4 is ideal for applications such as field search, sea rescue, long-distance signaling, and other scenarios where powerful spotlighting is required. Its design caters to tactical use, and it features a stainless steel bezel. Notably, the W4 produces minimal floodlight and significant spotlight effects.

Specifications:

• Utilizes an LEP Emitter with a wavelength range of 400-700 nanometers, providing a beam angle of 1.8° and a lifespan of 10,000 hours.
• The power output is between 0.22 – 0.25W in High Mode, delivering a highly intense beam reaching up to 2,670 meters.
• Features a high-quality Acrylic lens with hard coating on both sides to prevent scratches and reduce reflection, allowing 98.5% light transmission.
• Constructed from aerospace-grade aluminum alloy with black hard anodization.
• The head of the flashlight is equipped with an SAE 304 stainless steel bezel to protect the lens.
• The contact system uses gold-plated springs on both sides for maximum electrical conductivity and is impact-resistant from a height of 1 meter.
• The Tail Switch is designed to withstand up to 50,000 presses and offers two modes: Low-High. The flashlight starts in High Mode, and the switch can be half-pressed to change modes. A full click locks the current mode.
• Utilize 21700 battery x 1 (Not included).
• The tail tactical switch is a forward clicky with a 50,000 press life.
• Includes reverse polarity protection to prevent damage from incorrect battery insertion.
• Low Voltage Warning: The flashlight will flash to indicate when the battery voltage is low.
• Over Discharge Protection: Prevents the battery from discharging below a certain voltage.
• Designed with a high-efficiency circuit without PWM (Pulse Width Modulation), ensuring noise-free operation.
• Temperature Control Protection: Automatically reduces brightness when the temperature reaches 60°C to prevent overheating.
• Impact Resistance: Can withstand impacts from a height of 1 meter.
• Waterproof: Designed with IP67 rating and double O-ring protection.
