The Logitech G G915 X LIGHTSPEED TKL (920-012747) is a tenkeyless (no numeric keypad) wireless mechanical gaming keyboard with low-profile GL Linear switches, LIGHTSPEED 2.4 GHz wireless, Bluetooth and a wired USB mode, in the US International layout. It is 22.6 mm thin with an aluminium top plate, double-shot PBT keycaps and per-key LIGHTSYNC RGB, and Logitech rates the battery at up to 42 hours with lighting at full brightness or up to 1000 hours with lighting off. In the box: the keyboard, the LIGHTSPEED USB receiver, a 1.8 m USB-A to USB-C charging and data cable, and documentation.
Compatibility — check before buying:
This is the Linear switch version — it is the quiet, smooth option with no bump. The same keyboard exists with the other GL switch types under different part numbers, so check the switch name before ordering. It has no numeric keypad; if you need one, the full-size G915 X LIGHTSPEED is part 920-012709 (Clicky). GL switches are low-profile and soldered: standard MX keycaps and hot-swap switches do not fit. LIGHTSPEED needs a USB-A port for the receiver (Windows 10 v1809+ or macOS 10.11+); Bluetooth works with Windows 11, macOS 11, ChromeOS, Android 4.3+ and iOS 10+. G HUB is optional.
Best For
✓ Wireless gaming without lag — LIGHTSPEED at 1 ms
✓ A clean desk: one receiver, one cable only for charging
✓ Switching between a gaming PC and a laptop over Bluetooth
✓ Low-profile typing with a flatter wrist angle
✓ Small desks and mouse-heavy FPS play where every centimetre counts
✓ Weeks between charges when RGB is turned down or off
Key Features
GL Linear low-profile switches
GL Linear switches have no bump and no click — a smooth 43 g press to a 1.3 mm actuation point. They are the quietest and fastest-feeling of the three GL options and the usual choice for FPS and for anyone sharing a room.
Three ways to connect
LIGHTSPEED 2.4 GHz through the included USB receiver for gaming at 1 ms, Bluetooth for a laptop or tablet, and wired USB-C when the battery is flat. The same receiver family pairs with supported Logitech G mice.
Battery that scales with lighting
Logitech’s figures: up to 42 hours at 100% RGB, up to 100 hours at 50%, and up to 1000 hours with RGB off (disabled from the brightness key). Charging is over the USB-C port with the supplied cable.
Aluminium chassis, PBT keycaps and metal roller
A low-carbon aluminium top plate keeps the 860 g board rigid; double-shot PBT keycaps do not shine; and a metal roller controls volume. KEYCONTROL in G HUB puts up to 15 functions on any key.

Frequently Asked Questions
How long does the battery really last?
It depends almost entirely on lighting. Logitech quotes 42 hours at full RGB brightness, 100 hours at 50% and 1000 hours with RGB switched off from the keyboard’s brightness key. With lighting off you are looking at weeks, not days, between charges.
Can I use it over Bluetooth on a laptop and LIGHTSPEED on my PC?
Yes. Keep the receiver in the gaming PC and pair the laptop over Bluetooth, then switch between them from the keyboard. Bluetooth is fine for typing; for gaming use LIGHTSPEED or the cable.
What is the difference between the G915 X LIGHTSPEED TKL and the wired G915 X?
The wired G915 X (920-012942 US International, Tactile) has the same switches, keycaps and chassis but no receiver, no Bluetooth and no battery. This model adds all three and weighs about 40 g more.
Which GL switch should I choose?
Linear (43 g) is smooth and quiet; Tactile (45 g) adds a bump without a click; Clicky (48 g) adds an audible click. This part number is Linear. Tell us which feel you want and we will point you to the matching part number.
Singular Expert Insight
Within the G915 X range this is the version to buy when you want the slim aluminium board without a cable across the desk and can live without a numpad — the TKL saves about 11 cm of width and 220 g over the full-size model. The wired G915 X is the value pick when the cable does not bother you. See the rest of our
keyboards and match it with one of our
wireless mice that shares a LIGHTSPEED receiver. Not sure which switch suits you? Tell us how and where you play and we will recommend one.
Buyer’s Guide
Buy it if
You want a 22.6 mm low-profile wireless board with GL Linear switches, LIGHTSPEED at 1 ms plus Bluetooth, up to 1000 h per charge with RGB off, in US International layout and you do not need a numpad.
Skip it if
You want a tactile bump or an audible click — choose the Tactile or Clicky part number. You want hot-swap switches or standard MX keycaps (GL is a closed low-profile system), or you need a different layout.
Also consider
Logitech G G915 X LIGHTSPEED (920-012709) if you need the numpad, or the wired G915 X (920-012942) to save money.
