Shadowhawk S1618 Rechargeable Flashlight

The Shadowhawk S1618 is a high-output rechargeable flashlight built for outdoor enthusiasts, emergency preparedness and professional use. It delivers up to 20000 lumens from a 30W XHM90.2 LED chip and runs for 12 hours on a single charge. The cylindrical aluminum body measures 22 x 5.5 x 17.5 centimeters and includes a USB-C port for convenient recharging.

Sustained Output and Beam Control

The adjustable focus slides between a 1200-meter spotlight and a 2160-square-foot floodlight without changing power draw. At full 30W output the light maintains consistent brightness for extended periods rather than stepping down after a short burst. The LCD power display shows remaining capacity with ±1% accuracy so users can manage runtime during long shifts or overnight trips.

Thermals, Noise and Power Draw

Passive aluminum construction dissipates heat silently with no moving parts or fan noise. The 30W LED operates within thermal limits during continuous use while the waterproof housing protects internal electronics from moisture. Power consumption scales directly with the selected mode and the rechargeable cell accepts USB-C input for flexible charging from power banks, vehicles or wall adapters.

Questions about this item

How much heat does the 30 W LED generate during extended use?

The 30 W XHM90.2 chip produces noticeable warmth at maximum output; the aluminium body acts as a heatsink, and the LCD power display lets you monitor remaining capacity so you can step down modes before overheating becomes an issue.

What charging equipment must I already have to recharge the flashlight?

A USB-C cable is included; you only need a standard 5 V USB power source such as a wall adapter, power bank or laptop port to recharge the internal battery.

Will the 1200 m spotlight beam work alongside the older halogen lantern I keep for camp?

Yes — the adjustable focus slides between a 1200 m spot and a 2160 sq ft flood, so you can use the narrow beam for distance while the lantern covers the immediate area.
