If you want a full-featured, quiet wireless keyboard with a massive battery, a comfortable gasket-mounted feel, and a standard layout for gaming or office work, the TH87 delivers strong value. Consider how much you're willing to adapt to a 40% layout versus enjoying the immediacy of a TKL.

What will you mostly use it for?
The TH87 is the more versatile choice for general use, winning in Gaming, Office, and Content Creation due to its standard layout, quiet operation, and long battery life. The Luma40 excels in portability for Travel and offers superior firmware support for Modding. For Programming, the choice is a tie and depends entirely on the user's preference for a compact, layer-based workflow versus a traditional key arrangement.
Pick the Epomaker TH87
- The TH87 offers a standard TKL layout with dedicated arrow and function keys, which are often used in gaming.
- Its vendor page lists a 2ms latency in wired mode, slightly lower than the Luma40's 3ms.
- The included silent linear switch options may be preferable for shared environments.

Epomaker Luma40 vs TH87: your questions
The TH87 has significantly better battery life. Its 10000mAh battery is rated for about 45 hours with RGB at brightest, or 200 hours with it off. The Luma40's 1450mAh battery provides approximately 7 hours with RGB on and 75 hours with it off.
No, the Luma40 is designed for Kailh low-profile switches specifically. Its hot-swap sockets are compatible with 5-pin Kailh low-profile mechanical switches, which have a different form factor than standard MX-style switches.
An ortholinear layout, like on the Luma40, arranges keys in a straight grid without the staggered rows found on a normal layout like the TH87. Proponents claim it reduces finger strain by allowing more natural vertical finger movement.
Yes, both keyboards list Mac and Windows compatibility. However, the TH87's vendor description notes that its programmable software is for Windows only, while the Luma40 uses cross-platform VIA/QMK software.
The TH87 is likely quieter. It offers silent linear switch options and features a comprehensive 5-layer sound-dampening system with PORON foam, IXPE switch pads, and a silicone bottom. The Luma40 has sound dampening but also offers clicky switch variants.
The Luma40 includes the keyboard, a detachable wrist strap with tools, a multilingual manual, a USB A-to-C cable, a 2.4GHz receiver, a 2-in-1 keycap and switch puller, and three extra switches.
The TH87 features a two-stage kickstand offering three adjustable typing angles: 6 degrees, 8 degrees, and 10.5 degrees. The Luma40 has a flat typing angle.
Yes, but the method differs. The Luma40 supports full key remapping, macros, and layers via QMK and VIA firmware. The TH87 uses proprietary programmable software, which its vendor page states is for Windows.
The Luma40 is far more portable. It measures 240 x 87 mm and weighs 410g. The TH87 measures 367 x 142 mm and weighs 1000g, making it over twice as heavy and much larger.
In 2.4GHz mode, the Luma40 has a 5ms latency, while the TH87 also has 5ms latency. In wired mode, the TH87 has a slightly lower latency at 2ms compared to the Luma40's 3ms.
The Luma40 uses a tray mount, where the PCB is fixed to a metal tray inside the case. The TH87 uses a gasket mount, where the plate holding the switches is suspended on rubber or silicone gaskets, typically resulting in a softer, more consistent typing feel and sound.
