Gateron Lunar Probe vs. SP-Star RedBlue

An in-depth look at the Gateron Lunar Probe and the SP-Star RedBlue switches—which one is the best fit for you?

Overview

When it comes to mechanical keyboard switches, two popular choices are the Gateron Lunar Probe and the SP-Star RedBlue switches, both of which are linear switches. The Gateron Lunar Probe stands out for its novel dual rail mechanism, ensuring stable and consistent keypresses. Known for its incredibly smooth and pre-lubed linear sensation, these switches also offer a subtle sound signature. On the other hand, the SP-Star RedBlue switches are favored by those seeking a medium-light typing experience. With a low-pitched sound profile and categorized as low-pitched, neutral, mild, thocky, and polished, these switches provide a unique typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

When comparing the housing materials of the Gateron Lunar Probe and the SP-Star RedBlue, both switches feature a polycarbonate top housing. This material creates a sharper, higher-pitched, and crisper sound profile due to its relatively stiff nature. Additionally, the translucency of polycarbonate makes it especially useful for switches intended for use with RGB lighting. However, the Lunar Probe's nylon bottom housing differs from the RedBlue's polycarbonate bottom housing. The nylon bottom housing elicits a deeper and fuller sound profile, as nylon is a softer plastic that absorbs more sound than harder plastics, resulting in a duller and rounder sound.

In terms of sound profile, the two switches will likely produce similar sharp, higher-pitched, and crisper sounds due to their shared polycarbonate top housing. However, the feel of typing on each switch may differ due to the difference in bottom housing material. The Lunar Probe's nylon bottom housing will provide a deeper and fuller typing experience, while the RedBlue's polycarbonate bottom housing may offer a clearer and more resonant feel. This highlights how the choice of housing material can impact not only the sound but also the overall typing feel of a switch.

Overall, the split in housing materials between the top and bottom housings of each switch means that the qualities of each material will be felt differently when typing on these switches. The impact of the bottom housing material will be more noticeable during the bottom-out sound and feel of pressing a key, while the top housing material will have a greater influence on the sound produced when releasing a key. This highlights the importance of considering both top and bottom housing materials when choosing a switch, as they can significantly affect the overall typing experience.

Weight

In comparing the actuation force and bottom out force of the Gateron Lunar Probe linear switch and the SP-Star RedBlue linear switch, it is evident that the Lunar Probe is lighter in terms of both forces. The Lunar Probe requires a mere 45 grams of actuation force and 50 grams of bottom out force, making it ideal for those who prefer a lighter typing experience. On the other hand, the RedBlue switch has an unknown actuation force and a bottom out force of 57 grams, which is slightly heavier than the Lunar Probe. The actuation force is crucial for triggering keystrokes efficiently, while the bottom out force determines the amount of pressure needed to press the key all the way down. Ultimately, the lighter Lunar Probe switch would be preferred for individuals looking for a more effortless typing experience, while the slightly heavier RedBlue switch would suit those who prefer a bit more resistance for a more substantial typing feel.

Travel distance

The Gateron Lunar Probe linear switch has a travel distance of 3.6 mm, while the SP-Star RedBlue linear switch has a travel distance of 4 mm. This means that the RedBlue switch has a slightly longer travel distance compared to the Lunar Probe switch. A 0.4 mm difference may not seem like much, but it can impact the overall feel and feedback of the switch when typing or gaming. Gamers who prioritize faster response times may prefer the shorter travel distance of the Lunar Probe switch, while those who enjoy a deeper keystroke may opt for the RedBlue switch. Ultimately, the choice between the two switches will depend on personal preference and typing style.

Typing experience

In terms of sound, the Gateron Lunar Probe switch is best characterized by its smooth and subtle sound signature, providing a pleasant typing experience without being overly loud. On the other hand, the SP-Star RedBlue switch is known for its low-pitched sound profile, giving off a more bass-heavy and mellow tone when typing. Both switches offer a unique auditory experience, with the Lunar Probe focusing on smoothness and consistency, while the RedBlue leans towards a deeper and more neutral sound. Ultimately, the sound produced by these switches will also be influenced by the keyboard and keycaps you pair them with.

When it comes to feel, the Gateron Lunar Probe switch offers an incredibly smooth and pre-lubed linear sensation, ensuring stable and consistent keypresses. The RedBlue switch, on the other hand, is described as providing a mild and polished typing experience, offering a gentle keypress with a smooth and refined finish. Both switches prioritize comfort and consistency in their feel, with the Lunar Probe emphasizing smoothness and stability, while the RedBlue focuses on a more approachable and polished typing experience.

Overall, both the Gateron Lunar Probe and SP-Star RedBlue switches offer unique qualities in terms of sound and feel. The Lunar Probe stands out for its smoothness and stable keypresses, with a subtle sound signature, while the RedBlue switch provides a low-pitched sound profile and a mild and polished typing experience. Depending on your preference for sound and feel, both switches offer reliable performance and a satisfying typing experience. Ultimately, using either of these switches will result in a similarly high-quality typing experience, tailored to your personal preferences.

Conclusion

To sum up, when deciding between the Gateron Lunar Probe linear switch and the SP-Star RedBlue linear switch, you should choose the Lunar Probe if you prefer a lighter bottom out force and value stability and consistency in keypresses. The Lunar Probe offers a smooth, pre-lubed linear sensation with a subtle sound signature.
