INTRODUCTION

    Wireless keyboards have gone through a quiet transformation over the past few years, shifting from “nice to have” peripherals into genuinely refined tools that can anchor an entire desk setup. What used to feel like a tradeoff less cable clutter in exchange for latency, battery anxiety, or inconsistent connections has steadily faded as the tech matured. Modern wireless boards now deliver stable links, responsive switches, multi‑device flexibility, and a level of polish that makes going back to wired feel almost archaic. They’ve become part of a larger movement toward cleaner, more intentional workspaces where performance doesn’t have to be tethered. And with that evolution as the backdrop, today’s review turns its focus to Logitech’s G915 X Lightspeed, a keyboard built to show just how far this category has come.

    Logitech designs software-enabled hardware solutions that help businesses thrive and unite people when working, creating, gaming, and streaming. As the point of connection between people and the digital world, our mission is to extend human potential in work and play, in a way that is good for people and the planet. Founded in 1981, Logitech International is a Swiss public company listed on the SIX Swiss Exchange (LOGN) and the Nasdaq Global Select Market (LOGI).

    Logitech’s G915 X Lightspeed brings wireless design built around tri‑mode connectivity, offering LIGHTSPEED 2.4GHz wireless, delivering the low‑latency link Logitech is known for, Bluetooth support for quick switching across devices and wired USB. It uses the company’s GL mechanical switches (available in Linear, Tactile, or Clicky) and supports KEYCONTROL through G HUB for assigning macros, layers, and per‑key functions. The keyboard includes LIGHTSYNC RGB with multiple onboard lighting effects (Fixed, Breathing, Ripple, Color Cycle, and Colorwave) that can be cycled directly from the board, 9 G-Keys, dedicated media controls, slim aluminum top plate (keeps the board rigid) and a smooth aluminum volume wheel. Logitech lists a 25.84 kg CO₂e carbon footprint for this particular model underscoring its sustainability reporting, and as for battery life it can reach up to 800 hours with RGB off (36 hours with Full RGB lighting and 90 hours at 50% brightness).

SPECIFICATIONS AND FEATURES

PACKAGING AND CONTENTS

Logitech uses a large gray box to ship the G915 X Lightspeed the front of which is taken by a large product picture, company logo, keyboard layout and main product features.

The four main product features are printed at the rear in 4 languages right next another product picture (partial this time).

Opening the box reveals the G915 X Lightspeed wrapped inside a paper cover.

Inside the box along with the G915 X Lightspeed keyboard you're getting a USB-C to USB-A cable, USB-A to USB-C adapter, USB-A LIGHTSPEED 2.4GHz dongle, compliance information, charger recommendation paper, warranty information and a quick start guide.

THE G915 X LIGHTSPEED

Measuring 475mm in length, 150mm in width and just 22.6mm in height the 1040g heavy G915 X Lightspeed with its brushed aluminum top plate looks nice.

The floating keys are actually almost as tall/thick as the housing of this keyboard.

5 G-keys are located on the far left of the keyboard and as usual can be adjusted at will.

For more G-key/buttons are uplaced on top. You also can control the lighting effects and brightness levels by the round brightness button (next picture) and 1-9 plus -/+ buttons while the F1 key can be used to cycle between default and customized layout, F2 to F4 keys can be used to load onboard profiles.

The 4 round buttons just over the F5-F8 can be used to turn on/off wireless connectivity, enable/disable gaming mode and set the brightness.

A lightspeed logo is placed just over the lock key (could also be where the transmitter is located).

The dedicated media controls with the aluminum volume wheel are placed on the right top corner.

A USB-C port and an on/off power button are both placed at the front of the keyboard as seen above.

The keyboard sits on 4 rubber feet and has both a spot for the USB-A dongle and two dual height adjusters (5mm for the first, 11mm for the second).

Here you can see the tactile brown switches the G915 X Lightspeed comes with (or to be more accurate, also comes with).

The tiny 2.4GHz dongle is nothing new, we've seen similar models used in the past, even by Logitech.

At full brightness the keys of the G915 X Lightspeed really stand out (short video is available both on YouTube and TikTok).

G HUB

Once again the G-Hub software by Logitech detects all compatible devices and lists them as pictures on the initial tab.

Clicking on the G915 X Lightspeed takes you to the LIGHTSYNC tab from where you can choose effects (10 available ones), colors, brightness level, speed and create your very own effects.

The assignments tab allows you to assign commands to any of the keys of the keyboard and also to expand game mode by adding more keys to disable once it's enabled.

From the initial tab you can also switch between software (PC) and onboard (memory) modes and as you can see the onboard mode is quite limited.

Finally, the new G-hub versions feature a beta feature which basically unlocks specific customizations for supported games.

AUDIBLE FEEDBACK

Many people ask my opinion on what keyboard they should get for their needs. Some want a “silent” model for use in their living room or even in their bedroom while others ask for a model with good audible feedback for use in the office or for gaming. Because of this I decided to test keyboards by placing our ExTech HD600 vertically over each keyboard (5cm distance) and typing NikKTech a total of 6 times with each (after that the max recorded number - max hold - is placed in the graph). I have to admit that this methodology may not be 100% accurate but it does give a good idea on what you can expect from each model since aside the type of switches used keycaps and keyboard material also matter.

CONCLUSION

    Three things stand out about the Logitech G915 X Lightspeed, its low profile brushed aluminum housing, available connectivity options (2.4GHz, Bluetooth & USB) and battery life. Yes, the 800 hours of reported battery life with all lighting turned off is not something I could test for during the 3 weeks of testing, but I did manage to surpass 33 hours with RGB lighting at 100% brightness (and that’s a very good number for a full size keyboard). Of course, RGB lighting and even the extra G-keys are also features worth mentioning but let’s face it, those we’ve seen many times in this industry by equally high-end mechanical keyboard models (as are the low-profile keys, although they are not a great fit for me). As for the G-Hub software it’s still among the best in the market but I do feel it could be more streamlined to make it easier for “regular” users to find their way around its settings.

   Right now, the G915 X Lightspeed retails for USD189.99 inside the USA (Amazon.com) and for 177.17Euros inside the EU (Amazon.de) and so it lands right in the middle of many similar high-end models in the market. Overall, the G915 X Lightspeed may not be the perfect wireless gaming keyboard but it’s still a very good offering by Logitech and well worth of the Golden Award.
