ACEBEAM L 19 V2.0 (hereinafter referred to as L 19 V2 version) is an upgraded version of the L 19 generation lamp bead. L 19 V2 is equipped with CREE SFT40 LED, which is more balanced in brightness and long-distance performance than the first generation OSRAM PM 1 LED. In addition, the appearance of L 19 V2 is the same as that of the first generation, without any upgrade.

L 19 V2 is packed in a white paper box with product photos and important parameters printed on the front. The maximum brightness of the white version is 2200lm, and the longest range is 1083 m. The maximum brightness of the green version is also 2200lm, but the longest range is 1520 m. The longest battery life is 94 days.

L 19 V2 is the same as the first generation in appearance, but the details are blackened, and the head pressure ring and the metal key in the middle are covered with black coating. Compared with the first generation of silver matte texture headband and metal buttons, V2 version looks stronger, cooler, more attractive and more aggressive.

In terms of size, L 19 V2, as a flashlight with a long shot of 1,000 meters, has a total length of 163.8mm, a maximum head diameter of 60mm and a tail diameter of 25.4mm, which is not really "big" in its class. On the contrary, thanks to the "smooth" transition between the head and the middle tube, L 19 won't give people a feeling of "why is this thing so big" when held in hand, and the overall design is relatively coordinated.

The head pressure ring of L 19 V2 is made of metal and shaped like a pinion, which is not too aggressive and has a certain probability of passing the subway security check. Its surface is covered with bright black coating, which has a certain contrast with the frosted barrel of L 19 V2.
There are two main points in the existence of metal pressure ring. First of all, there are many sharp parts in its gear-like shape. Although the attack head of this size will not cause much impact on the human body, it is still very helpful for breaking the window to save yourself. Secondly, the hardness of metal pressure ring is higher than that of aluminum alloy. When the flashlight encounters frontal impact (such as falling, breaking windows, and * tactical action *), it will not be deformed greatly, protecting the glass panel and lens behind it. After all, no one wants to break the flashlight glass before breaking the window that needs to be broken in an emergency.
Moreover, it can be seen from the side position that the thickness of the metal pressing ring of L 19 V2 is actually very large, unlike some flashlights which only have a thin layer in order to save costs. In this way, the overall hardness of the attack head is higher and it is more difficult to deform. Secondly, the glass is farther away from the outside, which also reduces the risk of scratches and bumps.

The highlight of L 19 series lies in the press ring and under the lens glass. The reason why L 19 V2 can reach the range of 1000m+ through the diameter of 60mm pan/tilt (the green PM 1 version even reaches the terrible range of 1500m+) is closely related to this TIR lens carefully polished by Boss Song.
A total internal reflection lens is called a total internal reflection lens. As the name implies, total internal reflection makes the light emitted by LED converge in one direction through the total internal reflection of the lens, which is essentially different from the traditional metal-plated reflective lens.
Compared with the metal reflective cup, TIR lens can achieve a more focused effect under the same size. Interested students can also search to see what the flashlight range of other brands (same LED, brightness and cup mouth size) is, or what the flashlight head size of other brands (same LED, brightness and range) is.
Although the material of TIR lens is acrylic, its manufacturing cost is not lower than that of metal lens, especially the smaller the divergence angle, the higher the TIR cost. Never look at acrylic lenses and have the illusion that flashlights are cheap. This is not absolute.

Because it is made of acrylic, TIR lens needs a layer of hard toughened glass to protect it from being scratched in daily use. L 19 V2 adopts a piece of ultra-transparent tempered glass with coating, which presents a beautiful blue-purple color under reflection.

TIR function is divided into two parts. The matte in the middle position provides a certain floodlight effect, and the surrounding circle is the area responsible for focusing light. However, due to the manufacturing process, "nozzle" will inevitably appear in TIR lens. Note that the black block at one o'clock of the lens is a nozzle, not a so-called "defect". This is inevitable.

L 19 V2 is exactly the same as the first generation TIR lens.

The maximum brightness of L 19 V2 after replacing SFT40 lamp bead can reach 2200lm, and the heat emitted is naturally not low. Therefore, five thick cooling grooves are designed on the outer side of the flashlight neck position corresponding to LED, which can increase the contact surface area between the flashlight and the air, accelerate heat dissipation, and cooperate with the temperature control downshift strategy to ensure the stability of the flashlight.

At the neck of L 19 V2, there is also a metal operation button located on the side of the flashlight. The surface of the button is coated with bright black film, which is more integrated with the flashlight than the silver metal button used in the first generation and will not appear abrupt. Moreover, its bright black texture is different from the matte texture of the barrel, which will not make the keys completely hidden in the barrel and difficult to distinguish.
The function of this side pressure switch is obviously different from that of the tail switch of flashlight. First of all, the side pressure switch can control the flashlight independently of the tail switch (including locking and unlocking). Secondly, it has a complete set of operational logic. Click the tail switch control switch, press the control gear to switch the switch, press and hold the switch off to enter the moonlight mode, double-click the switch off to be extremely bright, and three strokes directly enter the flash. The tail switch can be completely ignored and used as a pure side-press flashlight.

A battery indicator light is designed next to the side buttons. When the flashlight is turned on, the indicator lights up synchronously, and different colors are displayed to distinguish the current remaining battery power (green light means sufficient power, red light means insufficient power).

The middle tube of L 19 V2 adopts a roller channel similar to a chocolate bar, which looks clean and tidy. It can provide enough friction when holding the palm, and it can also quickly sweat and drain water because of the uneven grooves. With the tactical ring at the upper and rear, the grip is very secure.

The side of the flashlight tail cover is also designed with a deep groove, which can effectively discharge liquid, and it is more convenient to unscrew the tail cover to replace the battery.
The end of the tail cover and the switch rubber cap are designed in the same plane, and in some cases, the flashlight can be used upside down.

The switch at the tail of the flashlight is covered with a thick black rubber cap with ACEBEAM LOGO printed on it.
Because of the positioning tactics, the rear key switch of L 19 V2 can only control the bright gear position of the hand electrode, and press the switch to output full power. At this time, even the side switch will not participate in the shift logic.

L 19 V2 has no USB direct charging function designed for this purpose. In my opinion, it is a pity. Every time the battery runs out, unscrew the tail cover and take out the battery for charging.
The tail connecting thread adopts trapezoidal thread with smooth thread. By the way, L 19 V2 adopts the combination of double barrel and thread conduction, and the first generation adopts double barrel+end face conduction.
L 19 V2 is powered by a 2 1700 lithium battery. Take the manufacturer's 5 100 mAh as an example, the longest battery life can reach 94 days.

Here we can see that the tail cover uses a gold-plated spring to press the battery to ensure that the vibration will not cause the flashlight to flash or power off, and the metal sheet next to it participates in the conductive function of the inner tube.

L 19 V2 uses O-shaped rubber rings at each connection position to provide sealing effect. In addition, the flashlight of AISI's house is exquisite in workmanship, and the parts are closely matched, which brings the waterproof effect of 5 meters (IPX8 level) underwater to L 19 V2, and it can be used in shallow water, not to mention raining. But try to avoid sudden contact with cold water when the flashlight is very hot. Everyone knows the principle of thermal expansion and cold contraction. Excessive temperature shock may cause water to enter the flashlight (even professional diving flashlights should be avoided as much as possible).
After a period of use, remember to check whether the sealing ring around the flashlight is worn and carry out regular maintenance to avoid affecting the sealing effect.

The temperature rise test of L 19 V2 shows that the hottest position of L 19 V2 is basically stable in the early 50s after starting for 6 minutes at room temperature of 24.5 degrees, with full batteries and no wind, and the temperature control is acceptable, so it will not be too hot to use.

Then the lighting test was carried out when the battery was fully charged. In the second minute, L 19 V2 was downshifted to 1600lm, which was roughly consistent with the instructions. Then it stabilized for about 18- 19 minutes before downshifting to the next gear (1200lm), which surprised me. After all, the stable output time of 1600lm in the official manual is 10 minute, which is half shorter than my measured time. I wonder how hot the temperature was in Guangdong during the exam. Anyway, it directly proves that low temperature has a great influence on flashlight downshift.
The test started at 8: 00 pm on 5 1 0, and automatically turned off at 2 10. It stood firm for an hour and a half, which was similar to the official propaganda. However, I didn't use the official original battery for the test, so there is nothing to refer to for battery life.

The highlight of L 19 V2 is that TIR lens with very small divergence angle is adopted, and the longest range reaches1083m with SFT40LED with maximum brightness of 2200LM. It is a proper long-range flashlight.

The effect of TIR lens is very different from that of traditional metal reflective cup, with strong focusing and weak floodlight spot, which is very suitable for providing long-distance lighting. When buying, you must match your own needs. If there is a certain demand for floodlighting, it should be carefully considered.
The following four photos were taken in the fog, so the light column looks more obvious, and the luminous characteristics of TIR can be made stronger (when illuminating distant targets, the position under the feet is basically black).

The first angle of view is as follows: there is basically no floodlight interference in the near position, and the distant target can be seen more clearly.

L 19 Comparing the lighting effects of the second generation and the first generation, the SFT40 lamp bead used in the second generation has higher brightness and larger luminous area than the PM 1 used in the first generation, so the light spot is larger. You can choose a more suitable version according to the contrast effect. The second generation SFT40 is used to correct the spot color temperature.

The above is the personal experience of ACEBEAM L 19 V2. ACE's workmanship can be completely closed, exquisite workmanship, excellent face value and human-computer interaction design left a very deep impression on me. The maximum brightness is 2200lm, and the longest range is 1083 meters. It is designed with a single lithium battery and can be used for outdoor exploration and hunting in pursuit of lightweight.
It's just that this upgrade from the first generation to the second generation can only be regarded as a small-scale change, not a big upgrade. Here, I look forward to a greater span of improvement in subsequent performance.
