Logitech G915 X LIGHTSPEED Full Size Low Profile Wireless Gaming Keyboard

The 2024 rebuild of Logitech's flagship low profile board. The X generation swaps in a cross style switch stem, drops actuation to 1.3mm, thickens the aluminium top plate to 1.5mm, moves to USB-C, and replaces the old ABS keycaps with double shot PBT. Full size layout with a numeric keypad and nine dedicated G keys for macros.

Before you buy

G915 X on its own does not mean wireless. Logitech sells a G915 X Wired that has no LIGHTSPEED and no Bluetooth, in black only, with Linear or Tactile switches. This is the single most common mis order in the range. Only the SKU carrying LIGHTSPEED in the name is the wireless model.

Full size and TKL have different battery ratings. The TKL is rated 42 hours at full RGB and 1000 hours with lighting off. This full size board is 36 hours and 800 hours. Listings elsewhere frequently copy the TKL figures onto the full size version.

Switch and colour are tied to the part number. Tactile in white and tactile in black are different SKUs. Confirm both against the part number rather than the product title.

Keycap compatibility changed with the X generation. The new cross stem is not the original G915 hook stem, so low profile keycap sets bought for the older G915 are not a safe assumption.
