HMX FJ400 vs. Gateron Luciola

Overview

When considering mechanical keyboard switches, the HMX FJ400 and Gateron Luciola stand out as intriguing options for enthusiasts looking for a linear experience. The FJ400 is celebrated within HMX's Film switch lineup for its balanced sound profile, providing a middle ground that appeals to users seeking a smooth, uninterrupted typing experience without the distractions of excessive noise. On the other hand, the Gateron Luciola not only brings a unique visual element with its glow-in-the-dark feature but also offers a medium heft that results in a smooth and bouncy typing feel complemented by a distinctive sound likened to a “can of spray paint being shaken.” While both switches share the linear designation and promise a fluid typing experience, their differing sound profiles and tactile feedback may influence your choice depending on personal preferences. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The HMX FJ400 and the Gateron Luciola both utilize distinct materials for their top and bottom housings, leading to a variety of auditory and tactile experiences for users. The FJ400 is equipped with POM for its top housing, which is known for producing a deep and muted sound profile that many enthusiasts find pleasing. In contrast, the Luciola's proprietary INK blend for its top housing yields a higher-pitched, clacky sound. The difference in the sound produced by the two switches can significantly affect the typing experience, as POM's softer nature dampens the soundwaves creating a fuller, less pronounced sonic feedback, while the INK blend generates sharper acoustic properties.

Examining the bottom housings reveals a similar yet contrasting story. The FJ400 employs a nylon bottom housing which contributes to an overall deeper and rounder sound, effectively absorbing sound waves and creating a more subdued auditory response. On the other hand, the Gateron Luciola utilizes the same proprietary INK blend for both its top and bottom housings, resulting in a consistent high-pitched sound profile throughout. This similarity in material for the Luciola means that both the bottom-out feel and the release sound will resonate with that higher-pitched characteristic, offering a lively and engaging typing experience that stands in stark contrast to the FJ400's deeper, muted quality.

Ultimately, the variations in housing materials between the HMX FJ400 and Gateron Luciola exemplify the profound impact material choice has on a switch's sound profile and overall feel. While the FJ400's mixed material approach splits the auditory experience between deeper sounds in the bottom housing and muted tones in the top, the Luciola’s consistent use of the INK blend delivers a unified sound. Consequently, one can expect notably different results in terms of sound profile between the two switches, with the FJ400 leaning towards a more subdued acoustic experience and the Luciola offering a brighter, crisper feedback that many typists may find more satisfying.

Weight

When comparing the HMX FJ400 linear switch to the Gateron Luciola linear switch, a notable difference can be observed in their actuation and bottom out forces. The FJ400 has an actuation force of 50 grams and a bottom out force of 58 grams, making it the lighter option of the two. In contrast, the Luciola requires a slightly heavier actuation force of 55 grams and exhibits a bottom out force of 60 grams. This means that the FJ400 may be more suitable for users who prefer a lighter touch for extended typing or gaming sessions, while the Luciola caters to those who favor a firmer feel when typing. Despite both switches falling into the medium force category, the FJ400 is the lighter choice, potentially making it a better fit for those looking for ease during long periods of use.

Travel distance

The HMX FJ400 linear switch and the Gateron Luciola linear switch exhibit different travel distances, with the FJ400 measuring 3.8 mm and the Luciola at 3.6 mm. This makes the Luciola the shorter option, catering to those who prefer a more responsive keystroke, which is advantageous for gaming. Conversely, the FJ400, with its slightly longer travel distance, might appeal to users who favor a more pronounced keypress that provides a sense of depth and feedback. The differences in travel distance between these two switches highlight the choices available to users based on their preferences for responsiveness versus key feel.

Typing experience

In terms of sound, the HMX FJ400 linear switch offers a balanced sound profile that sits comfortably between too muted and overly loud, making it versatile for a variety of typing environments. On the other hand, the Gateron Luciola presents a lively auditory experience characterized by clacky, chirpy, and marbly qualities. Imagine a keyboard that, with its high-pitched tones, delivers a sharp and crisp sound akin to a snappy percussion instrument, creating an engaging acoustic atmosphere that stands out in contrast to the FJ400's more neutral profile. This unique auditory experience from the Luciola may appeal to those who enjoy a more vibrant soundscape, while the FJ400 will likely suit users looking for a more subdued yet pleasing sound.

Regarding feel, the FJ400 boasts an unknown characteristic that leaves room for speculation about its typing experience. Conversely, the Gateron Luciola switches are described with several favorable attributes. With a combination of snappiness, buttery smoothness, and polished touches in the keystrokes, the Luciola promises an engaging and responsive typing experience. Users can expect the sensation of an effortless and fluid action with every keystroke, making it a joy to type on. The Luciola’s design may facilitate a more lively and dynamic interaction as opposed to the potentially unremarkable feel of the FJ400.

In conclusion, while the HMX FJ400 linear switch focuses on a balanced auditory profile and has an undefined feel, the Gateron Luciola linear switch excels with a rich and vibrant sound experience paired with a lively and smooth typing sensation. For those who appreciate a mix of auditory engagement and responsive feel, the Luciola shines brightly. However, if a user gravitates towards a more neutral sound and is open to exploring the unknown tactile qualities of the FJ400, they can expect to find satisfaction in a different, yet potentially harmonious typing experience.

Conclusion

To conclude, choosing between the HMX FJ400 and the Gateron Luciola linear switches ultimately depends on your personal preferences and intended use. If you’re looking for a balanced sound profile and a medium bottom-out force that allows for a versatile typing experience, the FJ400 is an excellent choice. It offers a smooth keystroke that is ideal for both typing and gaming without any overwhelming auditory feedback. On the other hand, if you are drawn to unique aesthetics and a more distinctive auditory experience, the Gateron Luciola should be your go-to. Its ability to glow in the dark adds a fun visual effect, while its slightly heavier actuation and clacky, high-pitched sound profile provide a lively and responsive typing feel. If you enjoy a touch of excitement and are willing to embrace a switch that delivers a snappy, polished feel, the Luciola may well enhance your keyboard experience. Ultimately, consider what feels and sounds best to you, as both switches offer their own charm and suitability for different typing styles and environments.
