The Y300™ Ultra is a versatile, ultra-compact, dual-output LED flashlight featuring many innovative attachment options including a magnetic base, a quick-detach belt clip, and a two-way steel pocket clip. Its Total Internal Reflection (TIR) lens focuses 500 lumens of LED-generated white light into a high-intensity beam with significant reach and ample surround light for peripheral vision. The Y300 also offers 15 lumens on its low-output setting for situations where maximum output may not be necessary or when extended runtime is desired.

The Y300 features a unique, integral magnetic base that attaches to a variety of metal surfaces—making it ideal for hands-free operation. This magnetic base also accepts an included quick-detach belt clip that permits the Y300 to attach to a belt or pack for easy access. A steel two-way pocket clip is also included and can be easily installed to provide secure attachment options, such as clipping the Y300 to the bill of a cap or carrying it in a pocket.

Activating the Y300 Ultra is done via its toggle switch that allows easy one-finger or thumb operation—press the switch on either side for high-output momentary-on activation, rotate the switch up or down for constant-on activation. The low-output setting is easily accessed by pressing (for momentary-on) or rotating (for constant-on) the switch within two seconds after initial activation.

Precision machined from aerospace aluminum with a Mil-Spec hard-anodized finish, the durable Y300 Ultra is also O-ring and gasket sealed to help keep out debris and moisture, making it a reliable illumination tool for a wide variety of applications. Its body was designed to accommodate a side-by-side battery configuration, which creates a shorter overall length and makes the Y300 ideal for fitting in the palm of the hand.
