Logitech G903 LIGHTSPEED Wireless Gaming Mouse with HERO 25K Sensor, 25,600 DPI

Ambidextrous Wireless Gaming Mouse

The Logitech G903 LIGHTSPEED pairs a HERO 25K optical sensor with a 1 ms wireless link. Competitive players and workstation operators get raw 1:1 tracking without cable drag. The symmetrical shell accepts swappable side buttons for left- or right-hand layouts.

The sensor resolves 100 to 25,600 DPI in single-step increments set through G HUB. It tracks beyond 400 inches per second and 40 G acceleration with zero smoothing, filtering, or acceleration algorithms applied. Metal spring tensioning keeps the primary switches crisp across the full click travel and trims pre-travel.

A rechargeable cell runs up to 140 hours with LIGHTSYNC RGB active and 180 hours with lighting disabled. POWERCORE support lets the mouse draw power from a POWERPLAY mat during play. A braided micro-USB cable supports wired operation while the battery refills.
