Gateron Lunar Probe vs. SP-Star Polaris Gray
An in-depth look at the Gateron Lunar Probe and the SP-Star Polaris Gray switches—which one is the best fit for you?
Overview
When comparing the Gateron Lunar Probe and the SP-Star Polaris Gray mechanical keyboard switches, it's important to note the key differences between the two. The Lunar Probe is favored for its smooth and stable keypresses, thanks to Gateron's dual rail mechanism, offering a consistent linear sensation and subtle sound signature. On the other hand, the Polaris Gray switches provide a bouncy typing experience with a clean and clacky sound profile. While the Lunar Probe excels in stability and smoothness, the Polaris Gray stands out for its unique typing feel and sound. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
In comparing the housing materials of the Gateron Lunar Probe and the SP-Star Polaris Gray, we see that both switches utilize polycarbonate for their top housings. This results in a sharper, higher-pitched, and crisper sound profile, thanks to the stiffness of the material. Additionally, the translucency of polycarbonate allows for better RGB lighting effects. However, where the Lunar Probe features a nylon bottom housing for a deeper and fuller sound profile due to its softer nature, the Polaris Gray opts for a polycarbonate bottom housing for a consistent clear and resonant sound.
While both switches share the use of polycarbonate for their top housings, the difference in bottom housings results in distinct sound profiles. The Lunar Probe with its nylon bottom housing offers a deeper and fuller sound when typing, while the Polaris Gray's polycarbonate bottom housing contributes to a sharper and crisper sound. This demonstrates how the choice of housing material can significantly impact the overall sound experience of a keyboard switch, even when the top housing remains the same. Additionally, the split between the qualities of the bottom and top housings highlights the importance of considering both when designing a switch for specific sound preferences.
In conclusion, the housing materials of the Gateron Lunar Probe and the SP-Star Polaris Gray play a crucial role in shaping the sound profiles of these switches. While both switches use polycarbonate for their top housings, the differences in bottom housing materials create distinct typing experiences. Whether it's the deep and full sound of nylon in the Lunar Probe or the sharper and crisper sound of polycarbonate in the Polaris Gray, each material brings its own unique qualities to the overall sound profile. Ultimately, the choice between nylon and polycarbonate for the bottom housing can impact the typing experience and sound feedback of a keyboard switch.
Weight
When comparing the actuation force and bottom out force of the Gateron Lunar Probe linear switch and the SP-Star Polaris Gray linear switch, it is evident that the Lunar Probe is lighter in both aspects. The Lunar Probe has an actuation force of 45 grams and a bottom out force of 50 grams, making it a relatively light switch overall. In contrast, the Polaris Gray has an unknown actuation force but a bottom out force of 67 grams, indicating a medium-heavy feel. Those who prefer a lighter typing experience may lean towards the Lunar Probe for its lower forces, allowing for longer typing sessions with less fatigue. On the other hand, the Polaris Gray would be more suitable for individuals who prefer a stronger push feel and a more substantial typing experience. Ultimately, the choice between the two switches will depend on personal preference for typing feel and force requirements.
Travel distance
The Gateron Lunar Probe linear switch has a shorter travel distance of 3.6 mm compared to the SP-Star Polaris Gray linear switch which has a slightly longer travel distance of 4 mm. The Lunar Probe's shorter travel distance may appeal to gamers looking for faster response times, while the Polaris Gray's longer travel distance can provide a more satisfying key press for those who prefer more depth in their switches. Ultimately, the choice between the two switches will depend on individual preferences for travel distance and how it affects the overall typing or gaming experience.

Typing experience
In terms of sound, the Gateron Lunar Probe linear switch is known for its subtle and smooth sound signature, providing a quiet typing experience. On the other hand, the SP-Star Polaris Gray linear switch is described as having a low-pitched, clean, and clacky sound profile. The Lunar Probe may be more suited for those looking for a quieter typing experience, while the Polaris Gray may appeal to individuals who enjoy a bit more auditory feedback while typing. Ultimately, the sound preference between the two switches will come down to personal preference and the overall setup of the keyboard.
When it comes to feel, the Gateron Lunar Probe linear switch is praised for its stability and consistent keypresses, offering an incredibly smooth and pre-lubed linear sensation. In contrast, the SP-Star Polaris Gray linear switch is said to provide a bouncy typing experience, offering a mild and polished feel with reduced friction and smooth key travel. The Lunar Probe switch may cater to those who prioritize stability and consistency in their typing experience, while the Polaris Gray switch may appeal to individuals who prefer a softer and more refined typing feel. Again, the choice between the two switches will depend on personal preference and typing style.
Overall, both the Gateron Lunar Probe linear switch and the SP-Star Polaris Gray linear switch offer unique characteristics in terms of sound and feel. While the Lunar Probe provides a quieter and smoother typing experience, the Polaris Gray offers a bouncier and more tactile feel. Ultimately, the decision between the two switches will depend on individual preferences for sound, feel, and typing experience. However, it is important to note that both switches offer high-quality performance and can provide satisfying results for users, ensuring a pleasant typing experience regardless of the choice made.
Conclusion
To wrap up, when choosing between the Gateron Lunar Probe linear switch and the SP-Star Polaris Gray linear switch, consider the bottom out force, sound profile, and feel that best suits your preferences. If you prefer a lighter keypress with stable and consistent keypresses, then the Lunar Probe would be a great choice for you. On the other hand, if you enjoy a medium-heavy keypress with a bouncy typing experience and clean, clacky sound profile, then the Polaris Gray may be the better option. Ultimately, your decision should be based on what feels most comfortable and enjoyable for your typing style.
