Logitech G915 X Lightspeed TKL is available in three versions with different switches and we have visited the version with Tactile switches. At the same time, it is also available in a black or a white version, where we got the black one. However, the white version is only available with Tactile switches.

A tour around the Logitech G915 X Lightspeed TKL

If you have become familiar with Logitech's previous Logitech G915 TKL, then you will immediately recognize the design here, because it is almost 100% the same. I actually couldn't immediately tell the difference between the two. However, the only external difference is also immediately that Logitech has switched to USB C for charging.

The most obvious thing at first glance is the low design. The G915 X TKL is a low-profile keyboard. This naturally creates a different look than the classic "high" keys.

Logitech's GL switches with associated keycaps are about half the height of traditional mechanical gaming switches. Low profile is of course not something that Logitech invented itself, and there are also other alternatives on the market, from manufacturers such as Corsair. However, it is still a fairly small segment.

Personally, I'm really happy with the look you get with a low-profile keyboard. It is also a bit of a different writing experience, which I personally also enjoy. It is not something that is particularly pronounced during gaming, but more so when writing.

In addition, of course, as the name indicates, it is a TKL keyboard, so in addition to being compact in height, the G915 X is also TKL in its overall size, as there is no NUM pad. It is somewhat a matter of taste whether you prefer a keyboard with or without. For gaming, however, it can be an advantage, as the smaller footprint can provide a better position when there is more room for the mouse.

As I said, the G915 X TKL is available in two variants, but the version we received for testing is made of dark brushed aluminum with black keys.

Only the top of the keyboard is aluminum, while the rest is plastic. However, the build quality is really good and there is no flex to trace in the frame. The G915 X TKL feels solid and also weighs well due to the battery. So it stands firmly on the table.

The keys are closer together in the same style as you know from, for example, laptop keyboards. It gives a more closed look and it also means that you can see very little of the RGB lighting between the keys.

In relation to the RGB lighting, there is light in all the keys. However, it is only in the primary functions of the keys. The keys that have several functions, such as %, & or similar. does not have light in these parts of the key. This means that they can be difficult to see in a dark room if you don't have full control of where everything is. This is simply because the RGB LED is located at the top of the switch, so only the top part of the keycap on top can be illuminated.

It's a minor detail, but it's a shame it's not done better on a keyboard in this price range.

All keys have a matte soft touch surface, which feels really nice. However, I may be concerned about how nice they will continue to be after prolonged use. However, the keycaps are in Double Shot PBT, so the durability should generally be top notch.

In our test sample, Logitech's Tactile GL switches are used, but the G915 X TKL is also available with Linear or Clicky. The tactile variant can probably best be compared to Cherry MX Brown switches, and also has a brown color.

There is a slight difference in the contacts from the previous version of the G915 TKL. Logitech has changed the design of the switches so that they now have a standard low profile MX stem. This means that it is easier to replace your keycaps with third-party ones if you want to.

The previous version had a special Logitech design that made it impossible. So plus in the book for standardizing it.

At the top of the keyboard we get an illuminated Logitech G logo and a number of function keys. On the left side there are buttons that can choose between Logitech's Lightspeed connection or Bluetooth along with a gaming button and one to adjust the brightness. On the right side, together with a nicely finished metal volume wheel, we also get the four classic media keys.

If we look at the underside, there is not much to look for. There are feet that can be adjusted in two steps of 4° and 8° respectively. There is also a small space where you can store the included USB dongle if you need to take the keyboard with you on the go.

On the top of the G915 X TKL we find the last two details, namely a power button and then a USB-C port for charging and/or connection to your PC. The G915 X TKL can be used both wirelessly or with a cable via USB. Logitech has thankfully upgraded to USB C here and not Micro USB as we saw on the previous version.

Software

Just like all other products in Logitech's G series, you have to go through their Logitech G Hub software if you want to adjust the settings and check the status of your Logitech G915 X TKL.

It's a bundled software, so if you have other Logitech G devices, they'll all be bundled here.

Via the software, it is possible to customize the lighting and effects on the keyboard. This can be done either via one of the many pre-installed effects, or you can build your own as you wish.

If you do it yourself, you can customize each key individually, with a multitude of effects and colors.

You can also choose to let the system control it, and supported games can also take control and adjust lighting and effects according to the game.

There are also super wide options for customizing the functions of the keys. You can basically change all keys to everything from shortcuts, media functions, Windows functions to Macro combinations.

Then you can bind both lights, effects and key functions to different profiles, so you can create special lights and key layouts from game to game if you want and coordinate it across several Logitech G devices, if you have it.

Overall, Logitech's G Hub software is proven and works well with a wide range of options and functions.

Testing

I've had the Logitech G915 X Lightspeed TKL on my desk for a few weeks now and it's been used for a good mix of work, general desktop use and gaming.

As I have already mentioned, I generally prefer keyboards with a low profile, and here the Logitech G915 X Lightspeed TKL lands super well.

The wireless Lightspeed connection is also gradually a solid and established protocol. It has not disappointed here and at no point have I experienced dropouts or instability.

One small detail that has annoyed me is when the keyboard wakes up from sleep. When I start it again, there is a slight lag. Partly on the keys, so if I just start typing, the first few inputs don't always come through.

However, the delay is also part of the light. I myself prefer a solid color that matches my surroundings without a lot of effects. I was also able to easily set up the G915 X Lightspeed TKL with that. But when booting from sleep, it briefly starts in the keyboard default light setup before switching over to the profile I've given it.

The latter is mostly an aesthetic annoyance, while the latter is more of a practical annoyance. It was a matter of just getting used to waking up the keyboard via e.g. the space key and then start using it. It is a bit of an annoyance that it is necessary though. In particular, the light is several seconds delayed before it changes.

Logitech itself states a battery time with the rather large range of 42 hours to 1000 hours, depending on whether you use the RGB lighting or not.

During my test with RGB lighting set to around 50%, I have not needed to charge the keyboard here about two weeks into my test.

Price

At the time of writing, I can find the G915 X Lightspeed TKL with an online price of just under 300$.

That is 100$  more than the Logitech G515 Lightspeed TKL that I tested not so long ago.

Conclusion

With the new G915 X Lightspeed TKL, Logitech has made a small update to a keyboard that I was already quite happy with.

It is a super solid and complete gaming keyboard for those who want the option of being wireless. The option of wireless Lightspeed connection, which can be supplemented with Bluetooth or cable, provides a super flexible keyboard that can serve more purposes than just gaming.

Build quality and materials are top notch, and personally I think the design is almost perfect. Logitech has chosen not to push flashy RGB lighting as one of its main selling points, and together with the clean and subdued design, it makes for a keyboard that makes an old dog like me happy.

When you can simultaneously use it wirelessly with an expectation of around 100 hours of use, if you just adjust the light settings a bit, it's hard to be dissatisfied.

The small updates to the previous version, so that we now have standard MX stems on the switches and USB C means that we are dealing with a super nice keyboard. It is probably not worth an upgrade if you already have the previous G915, but if you are in the market for a wireless gaming keyboard with flexible options and good battery life, then the G915 X Lightspeed TKL is a really good offer.

The price is, however, on the expensive side and Logitech's own Logitech G515 Lightspeed TKL can be had, for example, with basically the same features, for around 100$ less. The only immediate difference is the design and so we don't get dedicated media keys on the G515.

We end up with a final score of 8 for a solid and complete wireless gaming keyboard, which Logitech itself slightly undercuts with their G515.

Advantages:

• Good materials and build quality
• Stable wireless connection
• Long battery life
• Good software customization

Disadvantages

• The price is a bit on the high side
