Streamlight MicroStream USB 66601 Rechargeable LED Flashlight 250 Lumens

The Streamlight MicroStream USB 66601 delivers professional-grade illumination in an ultra-compact design that fits anywhere. This rechargeable pocket flashlight combines C4 LED technology with USB charging convenience, eliminating the need for disposable batteries while maintaining reliable performance.

What Makes This Different

The dual-output design provides both high-intensity 250-lumen maximum brightness and extended-runtime 50-lumen low mode, giving users tactical flexibility in a package smaller than most pens. Unlike standard battery-powered lights, the integrated USB charging system ensures the light stays ready without ongoing battery costs. The aircraft-grade aluminum construction with Type III hard-anodized finish resists impact and corrosion better than polymer alternatives.

Key Features

• Dual output modes: 250 lumens high / 50 lumens low with 3.5-hour / 6.5-hour runtime
• USB rechargeable lithium polymer battery eliminates disposable battery costs
• C4 LED technology produces intense white light with 68-meter beam distance
• Aircraft aluminum body with Type III hard-anodized finish for durability
• Compact 4.25-inch length weighs only 1.04 ounces for pocket carry
• Tail cap push-button switch with momentary and constant-on operation
• IPX4 water-resistant rating protects against rain and splashing

Real-world performance proves reliable across demanding applications from security patrols to equipment inspections. The focused beam pattern illuminates targets clearly at distance while the low mode preserves night vision during close-up tasks. Weather-sealed construction maintains function in rain, snow, and humid conditions. The rechargeable design ensures consistent brightness without the voltage drop common in alkaline batteries.
