How to Set Default Brightness on Holosun Micro Sight?

Using the correct brightness settings will improve your reticle’s display. If your red dot/circle point appears blurred or spongy, it is often due to the sight being set too bright for your ambient lighting conditions.

HOLOSUN (California) offers parallax-free and unlimited eye relief optics for shooting, hunting and law enforcement. They are powered by a solar cell under normal use and come with backup batteries to supplement power requirements in low light situations.

Shake Awake

The Holosun Micro sight is a great choice for those looking to save money on red dot sights. Not only does it come with all the features that you need for hunting and target shooting, but it also has a few extras that can make your life easier. One of these is the Shake Awake feature that will help conserve your battery.

The Shake Awake feature works by disconnecting the power source when your sight is not in use for a period of ten minutes, then re-activating it when you sense motion. This can save up to 50,000 hours of battery life.

Besides the Shake Awake feature, this sight is packed with other features that are worth taking note of. The reticle has a few different modes that will help you achieve your aiming goals. You can change between a red dot, a green dot, or a dual reticle (red dot and green dot) with the simple press of a button.

Another cool feature is the LED light-bending technology that uses a green diode instead of a standard red diode to produce a brighter reticle. This is important because the human eye is more sensitive to colors in the green spectrum.

To set your default brightness on the Micro sight, you can depress the two flush-mounted plus and minus buttons to adjust the reticle’s intensity. The reticle has 10 daylight brightness settings and 2 night vision compatible intensities.

The reticle also has a shake-off mode that will shut the sight down when you move it off your hand, which is great for those who need to keep their hands free when using it. Finally, there is a manual mode that allows you to adjust the reticle’s intensity with quick button presses.

The HS503GU is made from a black anodized aluminum body with multiple layers of coatings that include anti-reflection and abrasion resistance. The optic is designed for maximum durability while still providing crisp color correction and fog-free night vision. In fact, it’s built to withstand abrasions and dust better than most other sights on the market.

Solar Failsafe

One of the best things about the HS510C is that it draws power from a solar panel by default. This saves you the need to carry a battery around with you, especially in environments that might not be suited to a traditional CR2032 battery.

The HS510C also has a Solar Failsafe feature that will adjust the brightness of the reticle depending on the ambient light around it. This is great for situations where you might move from a dark room to a light one suddenly.

You should note that the Solar Failsafe function can only operate properly if you don’t cover the solar panel. Otherwise, the sight “thinks” that you’re in a dark place and automatically reduces the red dot brightness to night mode. This is a nice safety measure, but it can also be a bit annoying when you’re shooting in a bright spot and want to see the reticle clearly.

Once you have the reticle set to your liking, the HS510C is easy to use and straightforward to operate. Simply press and release the buttons at the top of the unit to turn it on and off, change the brightness settings or activate Shake Awake. The HS510C will remember your last brightness setting so you don’t have to repeat the process when you switch it off.

This optic also comes with 10 daylight brightness settings and 2 night vision (NV) settings. To use either, simply press and release the “+” or “-” button at the same time.

Holosun red dot sights are made from optical glass that is surrounded with multilayer coatings for maximum light transmission and wear resistance. These coatings also help to eliminate glare and reflections that can be harmful to your eyes.

Another benefit of the Holosun Micro series is that they offer many of the same innovations that are found on more expensive optics at a budget-friendly price. These features include a solar fail-safe, shake-awake, auto and manual brightness adjustment, and a wide variety of reticles.

The HS403C is an excellent option for those who are looking to add a high-quality red dot sight to their arsenal but don’t have a lot of money to spend. It features 12 brightness settings, Holosun’s Green Super LED with up to 50k hour battery life, and a 2 MOA dot. It also has an IP67 rating for water and dust resistance, making it a good choice for outdoor shooting.

Battery Life

The Holosun Micro sight features a green Super LED light source that can run for up to 50,000 hours. This is an impressive figure that means the sight will last a long time and will not need to be replaced for quite a while.

This model also includes Shake Awake technology that shuts off the power when it is motionless for ten minutes and then automatically starts up again. This will give you a longer battery life than many red dot sights.

In addition, the HS407K-X2 features 12 brightness settings that range from dim to bright for daylight and night vision. This makes it very easy to see the dot in any light situation.

You can adjust the brightness by pressing either the plus or minus button. These buttons are located on the flush mount of the sight, making it very easy to turn on and off.

When using the HS407K-X2 in auto mode, the reticle will monitor your ambient lighting and automatically increase or decrease the brightness to produce optimal visibility. This can help you see the dot in a dark room or on a sunny day, and prevents you from overexposure to the LED.

Once you’ve set your default brightness, the HS407K-X2 will remember these settings so that they are always available when you need them. This feature will save you a lot of hassle and can ensure that your sight is never out of reach in low-light situations.

The HS407K-X2 is a lightweight sight that can be mounted on a variety of different firearms, including pistols and rifles. It is made from light yet durable 7075 aluminum and comes with a multicoated lens that will help you see clearly in all conditions.


There are a few different reticle types that you can choose from for your Holosun Micro sight. These include illuminated, non-illuminated and tritium reticles.

Illuminated reticles have built-in illumination that helps the shooter see better in low-light conditions. They are also a good choice for daytime use since they won’t wash out or dim when you move your eyes around.

Non-illuminated reticles are black in color and can be great for daytime use but they will be incredibly difficult to see in low-light situations. They are often used in budget-priced scopes because they don’t cost much to manufacture, but they can be frustrating to view in any light condition.

With a Holosun Micro, you can set the default brightness so that the reticle won’t be overwhelmingly bright for ambient lighting or dark rooms. You can do this by adjusting the optic’s settings within auto mode or manually using a plus and minus button.

Once you’ve got your sight’s reticle brightness setup, it’s time to check it out in the field. Most red dot sights have a version of Shake Awake technology, which automatically turns on your sight if it’s turned off after a set amount of time. This feature can save a lot of hassle for the shooter and reduces battery usage, making it one of the most useful features you’ll find in a red dot sight.

You can also set your Holosun Micro sight to a manual brightness setting where you can control the brightness with button presses, or by disabling automatic sensor adjustments. This is a handy feature for the beginner who doesn’t have experience with sights yet, as it allows them to get used to the sight without worrying about brightness settings.

If you’re looking for a reliable and durable red dot sight, the Holosun 407K-X2 is a good choice. It’s compact, lightweight and comes with a clear lens. It has a low profile mount that fits most pistols and rifles. It also has a battery that can last 50,000 hours with the 2 MOA dot and 20,000 with the 65 MOA ring reticle.
