Tournament-Ready Tenkeyless Keyboard

The PRO X TKL LIGHTSPEED is a wireless mechanical gaming keyboard built for competitive players who need a compact layout without a number pad. It uses GX Brown tactile switches and double-shot PBT keycaps in a white chassis. The tenkeyless form factor saves desk space for mouse movement during high-stakes matches.

LIGHTSPEED Wireless Practical Limits

The keyboard connects via a USB LIGHTSPEED adapter with a 1 ms report rate and operates up to 32.81 ft (10 m) from the receiver. Battery life reaches up to 50 hours per charge using the included 6 ft USB-A to USB-C cable. A Windows 10 or later PC with a USB 2.0 port and internet access is required for Logitech G HUB software configuration.

GX Brown Tactile Switch Feel

The deciding specification is the GX Brown switch, which provides a discernible tactile bump without an audible click. This suits typists and gamers who want physical feedback on actuation but prefer a quieter keystroke. Buyers who want a linear press without a bump or a loud clicky sound should consider other switch types.

Questions about this item

Should I pick the GX Brown tactile switches or a different switch type?

This model comes with GX Brown tactile switches and dual-shot PBT keycaps; no other switch option is offered for this SKU.

What does the 1 ms report rate mean during gameplay?

The keyboard sends input updates to the PC every millisecond over the LIGHTSPEED wireless link, matching wired latency for competitive play.

How does the USB 2.0 connection limit the keyboard?

The USB 2.0 port powers the LIGHTSPEED adapter and handles firmware updates via G HUB; bandwidth is not a bottleneck for keystroke data.
