How to use outdoor cycling flashlight brands more efficiently

Daily mode four lighting flash brightness levels, two brightness levels for lighting spot image search mode. You can see the brightness of the light, but the center point is not dazzling, and the flooding effect is ideal, but there is no obvious difference between the prominent and super bright feeling of the search mode.

Reflection of Crazy Night:

Summary: The daily search mode of night test results and the impact of night shooting experiments. Practical experience shows that 860 lumens output brightness, 4 points of light, strong penetration, long irradiation distance, and ultra bright mode of 200m can still distinguish the brand profile of object wheel flashlights. At night, the brightness of general flat media can be used, and in complex road conditions, high brightness is sufficient to meet the lighting needs.

Brightness and distance testing

In order to better describe the changes in irradiation distance and brightness of EA4, residents were tested.

Abstract: The first two images were tested in a parking lot, with high output, ultra-high brightness output, and a visual lighting distance of about 200 meters. After shining the 8-story high image in the ultra-bright range, the obvious wall illumination can be said to be the perfect performance, brightness, and distance of EA4.

For assistance, flashing lighting and SOS, beacon testing

Waterproof testing

EA4 nominal IPx8 waterproof, with an average water IPx8 level from a distance of 30 meters from the top of 1.5 for 30 minutes, without affecting performance and without water leakage. Summary: After 30 minutes, ea4 can still function normally when placed in water. The safety and health of the lampshade, no lights, turn on the flashlight, keep the battery room dry, and ensure that the EA4 waterproof is in place. Due to limitations, the test time for non working conditions is at a depth of 2 meters, but EA4 domestic waterproofing is more sufficient to meet normal requirements.

Low temperature test:

Officially unmarked low-temperature applications, I tested in a low-temperature environment.

Low temperature environment simulation, the refrigerator freezer is at 12 ℃, open the freezer for 2 hours, and EA4 is still working.

Heat dissipation capacity:

Due to the current size of the flashlight, the cooling capacity of EA4 needs to be considered. The temperature of the hot test tactician in the shore inspection room is about 18 degrees Celsius. After 5 minutes, the torch continues to highlight the archival work, and touching the torch head is a bit hot.

But in the bright EA4, the torch will automatically decrease its brightness after 3 minutes of opening to prevent overheating.

Evaluation conclusion:

Advantages.

The 1-cylinder integrated design is unique, with exquisite craftsmanship and excellent technology, and has excellent waterproof performance;

Two sides adopt a two-stage switch function, voltage monitoring, and ultra-low light blue indication for convenient night positioning;

3 circuit functions, daily four plus search for two stalls, beacon, SOS, Flash many;

4 innovative "digital precise optimization technology" enables the EA4 optical system to achieve optimal performance, high efficiency, more perfect on-site output, brighter, more penetrating power, and irradiation distance;

5 small, beautiful appearance, light weight, and easy to carry;

6. 4AA battery charging facilities;

7. A cold white light, white light optional;

Disadvantages:

1. Switching the focus too many functions makes the operation complex;

Defects in the 2-roll design;

There is no significant difference in the brightness and smoothness of three super bright surfaces;

The consistency requirement for the batteries of four sets of batteries is very high;

Overall, what brand is a compact and powerful flashlight? It is easy to carry, has low cost, and is easy to use with AA batteries. The brightness of many stalls is available in various modes, fully meeting the needs of daily outdoor use.
