Smiling Shark SD8100 Rechargeable LED Flashlight with Zoom

TheSmiling SharkSD8100 is a high-power rechargeable LED flashlight with white and yellow light sources, so you can pick the right beam for clear nights, fog or rain. Its upgraded M60/M77 LED core has a stated output of 6,000–8,400 lumens, which makes it a strong pick for outdoor trips, emergencies and low-visibility situations.

A smooth mechanical zoom lets you switch between a wide beam for nearby areas and a tighter beam for distant targets. If you are looking for a reliable Smiling Shark flashlight for camping, night walks or power-cut backup, the SD8100 covers all of these in one metal-bodied unit.

It recharges through a 5V Type-C input and also has an integrated power bank function with a USB-A output port. A Type-C cable and a lanyard come in the box.

Key Features

• High-Power Dual Light Source: The upgraded M60/M77 LED core has a stated output of 6,000–8,400 lumens. This gives you a bright, far-reaching beam for outdoor use and emergencies.
• White and Yellow Light Modes: Switch between a white beam for general-purpose lighting and a yellow beam that improves visibility in foggy or rainy conditions. You can match the light to the weather.
• 10 Lighting Modes: Strong, Medium, Weak, Strobe and SOS modes are spread across both light sources. You get practical options for daily use, outdoor activities, signaling and emergencies.
• Mechanical Zoom: The zoom adjusts the beam from wide to focused. Use a broad spread for nearby visibility or a narrow beam for long-distance observation.
• Type-C Charging: The 5V Type-C input works with compatible USB power sources, and the cable is included. Recharging is easy without special chargers.
• Integrated Power Bank Function: The USB-A output port lets the flashlight double as an emergency power source. This is handy during outages or outdoor trips.
• Physical Power Indicator: The built-in display shows the power status at a glance. You can check the charge before heading out.
• High-Strength Metal Alloy Build: The metal alloy structure is made for durability and a firm grip. It suits rough outdoor handling.
• Silent Operation: The unit makes no operating noise, so it works well for quiet night use.
