Beauty in Symmetry & Minimalist Aluminum Aesthetics
Meticulously crafted from smooth, CNC-cut aluminum, the Luma40 aluminum keyboard is a statement piece for any desk. The aesthetics are rooted in minimalism with the unique 40% layout, with semi-transparent frosted white keycaps that elegantly diffuse the keyboard's RGB backlight. The legends and mac modifier signs are silk-screen printed, a subtle detail that adds to the refined look. The unique key alignment provides a cleaner visual, while the brand-embossed metal badge on the back adds a modern, elegant touch to the overall sleek design.


Ergonomic Ortholinear Layout
While traditional keyboards force your fingers into unnatural diagonal movements, a design left over from the era of typewriters, the Luma40 breaks from this outdated pattern with ortholinear layout, where keys are arranged in a perfectly aligned grid. For programmers or writers spending hours crafting their work, this thoughtful design minimizes finger travel and promotes a more natural, comfortable typing experience, to reduce finger strain for a more fluid workflow.


Padding Cushioned Tray-Mount
The Luma40 Low-Profile Keyboard comes with a superior shock-absorbing design, where layers of soft foams cradle the PCB from the metal frame. Every keypress is dampened to be satisfying with pleasing deep sound profile. The lubed low-profile switches, in half the height of traditional mechanical switches, puts less stress on your wrist to prevent pain from carpal or muscles strain.


QMK/VIA Custom Keyboard
Powered by the powerful QMK firmware, the Luma40 mechanical keyboard is a canvas for your creativity. Macros, Remaps, Layouts, Mod Tap and Any Key Functions, this custom keyboard is a joy to experiment. Map your most-used shortcuts for design software on one layer, create a dedicated number pad layer accessible with a single key press to help with data analysis, or program complex macros for intricate in-game maneuvers. With the Luma40 QMK keyboard, you can get the full-sized power with a compact 40% layout.


Hot-Swappable Switches
Interested in experimenting with different switch types without committing to a permanent setup? The luma40 hot-swappable keyboard is designed for keyboard enthusiasts. With 47 hot-swappable sockets, compatible with 5-pin Kailh low-profile switches, switch up keyboard style with ease with a simple pop-and-push. Quiet linear switch for late-night coding or a satisfyingly clicky switch for a weekend of gaming, enjoy the swift transition that keeps the Luma40 keyboard adapt to any task or mood.


Seamless Multi-device Connectivity with Tri-mode
Designed for the modern, multi-device lifestyle, the Luma40 wireless keyboard offers seamless connectivity across all your platforms. Fast and reliable 2.4GHz wireless mode for gaming, stable Bluetooth mode for on-the-go productivity with your tablet or laptop, or the traditional wired mode for zero-latency performance, the Luma40 keyboard works flawlessly across PC and Mac. Desktop, laptop, or tablet, the effortless switch between up to 5 paired devices makes the Luma40 the only keyboard you'll need for all your devices.


Per-Key Customizable RGB
Bring the Luma40 to life with its vibrant RGB backlighting. Fully adjustable with north-facing LEDs, the Luma40 backlit keyboard allows you to create custom lighting profiles that match your mood, your game, or your setup. Craft a truly unique visual experience that reflects your personality, with complete control over color, saturation, tone, brightness, and speed.

Compact and lightweight!
The texture is good, and it has the Japanese Technical Conformity Mark, so there’s no complaint.
To be honest, even if you only use it during WIN with VIA settings, it seems better to keep Layer 0 and 1 in the same arrangement.
There were times when the initial layer would automatically change to 1 when it was 0, and it wouldn’t return during layer switching. The problem disappeared when using only layers 2 and 3 separately.

I fell in love with the size and design at first sight and decided to purchase it.
I’m happy that such a product from Epomaker with technical certification is available.
There are no issues with usage, and since it’s my first time using an ortholinear layout and low-profile key switches, it might take some getting used to. However, I’m satisfied as it’s perfect for saving space indoors or for carrying around.

Amazing little ortholinear grid keyboard.
If you can grab this under $100 usd then this keyboard is definitely worth it.
The build is solid aluminum yet light and easily portable, overall build quality is about 8.5/10. It’s not perfect as there are minor issues such as some keycaps getting stuck if it is pressed down fully (they keycap have a tight tolerance around the switch and can get stuck when the board is warped from depression)
Other than that this is an excellent foray into ortholinear grid layout style keyboards.
Epomaker has really done a fantastic job with this luma40 and the p65 (along with the rest of the p series)

The store’s response was terrible, but I like the product itself.

The product came well packaged and the box wasn’t damaged at all, which is great. But I’m wondering if it originally didn’t come with a strap?

This is a challenging model that other mass production manufacturers do not attempt. Personally, I find it wonderful that you can properly use MOD-TAP. Whether you like keycaps depends on personal preference. It would be even better if a case that can be carried separately and fits perfectly were released.
