Application

The MegaStream USB is a must-have tool for automotive technicians, providing powerful, hands-free lighting for detailed inspections, diagnostics, and repairs in low-light conditions, such as: 

• Under-the-hood inspections: Its ultra-bright beam reaches deep into engine compartments, making it easy to spot leaks, worn belts, or loose connections. 
• Undercarriage work: The powerful 1,800 lm output ensures clear visibility when working under vehicles, helping technicians locate and fix issues faster. 
• Dash & interior repairs: The compact design fits easily in tight spaces, illuminating dashboards, consoles, and footwells. 
• Electrical troubleshooting: The bright, focused beam allows for precise identification of wires, fuses, and connections, reducing errors and rework.

Origin

The MegaStream USB was developed to provide high-lumen brightness in a compact, rechargeable EDC flashlight. The design addresses the need for powerful illumination in a handheld light while offering flexible charging.  

Features and benefits

• Three output modes: Choose between high (1,800 lm) for maximum visibility, medium (500 lm) for balanced brightness, and low (150 lm) for extended run-time, making it ideal for everything from quick, under-the-hood inspections to complex repair jobs. The adjustable brightness levels allow technicians to control the intensity of the beam based on the task. 
• Long-lasting performance: Up to 13 hours of run-time on low and 2 hours on high ensures technicians have reliable lighting throughout a full shift.  
• Sliding head cover: Keeps the USB-C charging port protected from grease, dirt, and debris, ensuring a reliable connection and long-term durability in shop environments. 
• Hands-free operation: The removable pocket clip allows technicians to attach the light to a uniform, belt, or tool cart, keeping both hands free for precision work under the hood or in tight spaces. 
• Rugged construction: Built with machined aluminum alloy, a Type II MIL-Spec anodized finish, and an unbreakable polycarbonate lens, this light is designed to withstand drops, impacts, and the tough conditions of an automotive repair shop.
