From the moment the torches are lit, human beings are in pursuit of light, and lighting products are changing with each passing day. Lighting equipment is the best choice for night travel.
Flashlights that can bring this kind of lighting brightness experience are generally called big killers by tube friends. Manker MANKER’s flashlight design is unique, highlighting the ultimate performance and quality, and has also launched flashlights with a large killer level. Almost every flashlight enthusiast has Manker’s products.
The flashlight I want to talk about today is the upgraded version of the Manke MK34 – MK34 II. Brightness is good, right? A full 26,000 lumens; is it small in appearance? It is not too big for children to hold; how is the specific performance? This article makes a brief introduction, referred to as “MK34 II” in the text.
12 lamp beads, I don’t know what the night is
The wide field of vision, clear field of vision, and large-scale uniform lighting effect make the night look like day, all relying on a flashlight.
The unique feature of the MK34 II is the equilateral triangular three-circle light head design. The 12 Cree XHP50.2 LED lamp beads are divided into three groups, with a maximum luminous flux of 26,000 lumens. There are four in each lamp head. The lamp beads are positioned neatly, the direction within the group is the same, and the groups form 120° with each other, with a strong sense of regularity. At the same time, there are also SST40 positive white light and warm white light bead options, but the luminous flux is slightly lower, but the light intensity and range are larger.
MK34 II uses three four-in-one micro-orange surface metal reflectors optimized for large-area lighting. The depth of the light cups is about 10mm. The shallow light cup, orange surface, and large light beads are floodlight flashlights. standard.
The lamp head adopts a double-sided coating anti-scratch optical lens, the coating is uniform, and the surface reflection is lavender, which can increase the transmittance of light, and it will be brighter when used.
The three sets of lamp beads almost cover the outer surface of the lamp head. Except for the small area of the lamp head pressure ring, it can be said that the area advantage of the large lamp head is maximized. The color temperature of positive white light is 6500K, and it does not need to be too far away to shoot the “yellow water” in the mouth of three cups of friends. The light path fully conforms to the full definition of large floodlighting.
From the perspective of the light beam effect, thanks to the large luminous flux, the MK34 II, a large floodlight flashlight, also has a very obvious beam of light, which is roughly divided into three layers, and can be seen clearly at the far end. The opening of the main spot of the light emitted from the tube is about 20°, the opening of the auxiliary spot is about 70°, and the opening of the outermost peripheral light can reach about 160°.
The light spots facing the wall of the three groups of lamp beads can also form a perfect circle, about 15 cm away from the wall, the diameter of the main light spot is about 12 cm, the internal brightness is uniform, and there is no strong reflection in the shape of concentrating points; the diameter of the peripheral auxiliary light spot is more than 40 cm ; It can also brighten the environment as a whole.
When used outdoors, you can feel the shocking effect of the 26,000-lumen floodlight. The lighting range has exceeded the coverage of the camera’s 16mm ultra-wide-angle focal length. You just feel that the eyes are bright, just like daytime, and your vision is clear and comfortable.
From the subjective perception of the human eye, the brightness of the MK34 II can be maintained at a distance of 50 meters without attenuation. The layering from near to far is better, but it will feel too bright and dazzling when used at close range.
The MK34 II is very suitable for use in a relatively open location. Due to the gear memory function, you can first memorize a normal-use medium brightness gear, which is close enough to use; in addition, the MK34 II can also quickly enter the extremely bright state, which can It is very convenient to use it to ensure that the required brightness can be called up at any time outdoors.
The most enjoyable practical experience is to use the MK34 II for a wide range of scans, even out of the corner of the eye can see clearly, night crawling search and rescue guarantees safety, and tongyou entertainment satisfies the senses.
For floodlights, the light range is not a strong point. However, due to the huge luminous flux of nearly 30,000 lumens, the MK34 II also has a good range. The distance from the other side of the small lake in the dynamic picture below is more than 200 meters. At each brightness level, the irradiation distance of the light gradually increases. Both stones and trees can be illuminated. For the MK34 II’s range of 280 meters, normal conditions are sufficient.
Overall, the brightness of the MK34 II has far surpassed that of car headlights, and the large floodlight features, whether it is facing the front or not, it will feel like a direct effect. When using, especially in the city, be careful not to turn on the extremely bright light casually to avoid potential safety hazards.
Minimum 0.1 lumen, moonlight gear for practical eye protection
The light can be like the day, and the dark can be like a firefly. The moonlight gear is also a major feature of the MK34 II. The brightest is 2 lumens, and each lamp bead is about 0.17 lumens, which is not dazzling at all. This is one of the main reasons why I like the MK34 II.
In a room with no lights at night, as long as you press and hold the switch of the MK34 II, you can turn on the moonlight gear. The human eye does not need to adapt to the change of brightness, and it can also see the surrounding things clearly. It is a very practical and commonly used function.
Moreover, the moonlight gear of MK34 II has 5 options between 0.1 and 2 lumens. As long as it is turned on, press and hold the switch to cycle, and release it to select it, and it can be memorized. The next time the moonlight gear is turned on, it will be the same brightness.
Due to the use of an efficient constant current dimming circuit, the MK34 II has no stroboscopic and whistling in the six constant-brightness gears and the optional brightness of the 5 moonlight gears, which can protect eyesight and make viewing more comfortable.
Rich accessories, convenient to carry and use
The MK34 II is packaged in a hard carton with a flip cover. The orange and black color matching of the Manke family includes a flashlight, a flashlight sleeve, a hand rope, a Chinese and English bilingual manual, and a spare waterproof sealing ring. It is also easy to go. Practical way.
The nylon flashlight cover is sturdy and high quality, with a Velcro MOLLE system mounting strap on the back, and a hanging loop. It is convenient to hang the MK34 II in a convenient location such as a backpack, belt, etc. It can also play a good protective role in a backpack.
There is a 4mm diameter hand rope hole at the end of the barrel, but the standard hand rope is too thin and looks a little weak. I have already made it for him.
I made a DIY paracord to replace it. When I use it, I can put the hand rope around my wrist to prevent the flashlight from falling off accidentally. It’s just that the edge of the opening of the hand rope on the barrel body is not polished, and it looks a bit sharp. Check the wear of the hand rope after using it for a period of time.
The plane on the side of the lamp holder comes with a standard tripod interface, and the interior is stainless steel thread, which is relatively stable and easy to install and fix the flashlight.
After being put on the shelves, the MK34 II becomes a fixed lighting device. It is very convenient to free the hands of the user and fix the lighting direction when camping or when there is a need for directional lighting.
Small and lightweight, unique appearance
MK34 II is made of aviation aluminum alloy material, which has the characteristics of low density, light weight, high strength and good heat dissipation. The triangular three-sided design is also unique in the flashlight industry, and its appearance can be described as distinctive.
The MK34 II is a three-lithium parallel-connected series-powered flashlight. The body is processed into a three-in-one battery compartment, and there is no battery holder to further reduce the weight. Conductive springs and contacts are gold-plated to reduce contact resistance and avoid oxidation.
The MK34 II tail cover is provided with two positioning pins, the positioning pins and the circuit board are coaxial with the tail cover but not fixed, and can rotate around the axis. This ensures that the circuit is always fixed when the tail cap is twisted, and the battery will not be scratched.
The weight of the empty barrel of the MK34 II is only 316 grams, and the weight of the three original 3100mAh power 18650 batteries is 458 grams, which is less than a kilogram. This is the first echelon in the light weight of the big killer.
The MK34 II is shorter and thinner than a standard 333ml can. The length of the barrel + tail cover is only 69mm, and the lamp head is slightly thicker to form a stop at the tiger’s mouth. The size of the handle is more suitable.
The MK34 II has a total length of 109.5mm, a barrel diameter of 43.8mm, a maximum width of 63.2mm, a minimum width of 59mm, and a tail cap diameter of 47mm slightly larger than the barrel. Compared with the 18350 flashlight and AAA corner lights of the same door, it does not appear bloated.
The surface of the MK34 II adopts the gun gray military-standard three-level hard anodizing process, which further improves the scratch resistance and wear resistance of the barrel. The appearance is oxidized without color difference, and the micro-matte texture also has a better tactile feeling.
The barrel body echoes the lamp head. There are three planes milled, and the three sides make the MK34 II have good anti-roll ability when placed. The barrel body and the tail cover have a large area of rings to improve the stability of the grip, and the tail cover has an axial vertical Pattern, easy to pinch and twist with fingers.
There is a stainless steel protection pressure ring on each of the three eyes of the MK34 II lamp head. The surface is chrome-plated, which is coordinated with the color of the lamp head. The depth of the pressure ring is about 3mm, which can effectively protect the lamp head components.
The lamp head of MK34 II has a large area, and the three-eye pressure ring forms a three-point support. The lamp head is placed downwards very stably, and there is no need to worry about the uneven surface bumping against the optical glass.
Likewise, the tail of the MK34 II is also very flat and stable when placed upside down. Here’s a suggestion: If you can standardize a special-shaped diffuser that fits the lamp head, the MK34 II will be a great camp light.
There are also two gold-plated positive contacts and gold-plated negative springs on the inside of the barrel close to the circuit board. The circuit has reverse polarity protection and a clear battery polarity prompt. The MK34 II is compact and can support flat head and 18650 battery with plate. To ensure performance and safety, it is best to use a power battery with the same specifications.
I have to say that MANKER’s special-shaped barrel design with a large arc triangle is really comfortable to hold. The joints of the hand just fit the corner of the arc. The palm falls on the plane of the barrel, and the grip is very stable, and the thumb can naturally rest on it. The position of the switch is ergonomic.
Side push switch, simple and clear hand-operated experience
The switch of MK34II is located on a plane near the top of the lamp head, slightly protruding from the surface of the lamp head. There is a chrome-plated stainless steel pressure ring of the same color as the lamp head on the outside. The diameter of the stainless steel button is 11.5mm, which ensures the accuracy of the operation.
The button surface is a concentric ring pattern, which ensures a good pressing feel. MK34II uses an electronic switch, the key travel is small, almost silent, the trigger has tactile feedback, and the response is relatively sensitive in general.
There is a three-color power indicator in the center of the button circle. After power on, the current power is displayed in three colors of blue (voltage>10.2V), purple (voltage>9.6V), and red (voltage>8.7V). It will remain on to clearly remind the user to replace the battery in time.
In addition, long press the switch, after the main light is turned on and the moonlight gear is turned off, this indicator light will turn on the breathing light function with the color of the current voltage, which is very convenient for locating the flashlight and switching at night.
MK34II has the gear memory function, click the switch at any time to open the memory gear (excluding the moonlight gear); long press the switch to turn on the moonlight gear; double-click the switch to quickly turn on the extremely bright, ensuring that the maximum output can be quickly reached, double-click again or long Press to return to normal gear.
After turning it on, long press the switch to realize the gear change of low light 140lm—middle one 650lm—middle two 1600lm—middle three 4500lm—high light 10000lm, just let go at the appropriate gear. To ensure safety, the extremely bright 26000lm is not within the normal gear cycle.
It is very convenient that no matter which gear is in the middle brightness, as long as you release the switch, long press it again to realize reverse dimming from high to low, so as to quickly reach the required brightness of the gear.
No matter it is on or off, as long as you triple-click the switch, the MK34II will turn on the strobe function of 26000lm. At this time, long press the switch, it will flash between strobe-beacon-SOS, and triple-click it again to return to the previous gear.
In order to ensure safety, the circuit of MK34II is also designed with a locking function. As long as the switch is quickly four-clicked in the off state, the main light flashes three times, that is, the key lock state is entered. Press the switch indicator again to enter the breathing flashing function, and the main light cannot be turned on; To unlock, simply four-click the switch again.
The MK34II is small and compact, the barrel feels good in the hand, and the switch position is relatively convenient. It can be controlled well with bare hands or with gloves. The dimming logic is simple and clear, and the practical experience is good.
Powerful performance, good battery life, smart temperature control, and waterproof
Although there are already a lot of batteries, in order to ensure the objective and rigorous data test, I still bought three original 3100mAh power batteries, and sometimes I feel a little hopeless when I fall into the pit.
Fully charge the battery, connect the illuminance meter and thermocouple thermometer to start the test, and the lamp head is about 50 cm away from the illuminance meter.
In addition to the moonlight, the MK34II’s illuminance steps become larger step by step. It is a floodlight with huge luminous flux. The maximum light intensity in the center can exceed 20,000 candela, and the illuminance also reaches 196,000 lux.
The huge luminous flux brings huge heat generation. There are three heat dissipation fins on the lamp head of MK34II. Although the appearance maintains a harmonious appearance, it does not help much to improve the heat dissipation capacity.
Judging from the data after turning on the extremely bright light, the temperature of the lamp head soared from less than 25°C at room temperature to nearly 70°C in a short period of time; after 1 minute and 10 seconds of downshifting, the output will be slightly higher than the illuminance of the middle and second gears, and Maintaining the constant current level output, after the lamp head temperature rises to a maximum of 71.8 ℃, it also begins to gradually decrease; the barrel temperature is relatively mild, with a maximum of only 45 ℃, and it feels hot to touch, but not scalded.
Next, I pressed the switch to turn on the high-brightness gear, and double-clicked it again to turn on the extremely bright gear. After downshifting, I turned on the fan to help dissipate heat, and the output performance returned to the high-brightness level and dropped again.
After that, the fan is turned off, and the MK34II circuit comes with an intelligent temperature control module. According to the regular change of brightness increase—temperature rise—trigger temperature control—decrease output—temperature drop—increase output, the output peak value will be smaller when there is no fan, indicating that the effect of the temperature control circuit is still Yes, it can guarantee the balance of output performance and flashlight temperature at any time.
At the beginning of the second hour, double-click again to turn on the extremely bright light, which is slightly lower than the output capacity when fully charged, and the temperature control circuit still works until the red indicator light is on for 1 hour and 20 minutes, and the illuminance is downshifted to the low-brightness gear.
During this process, the temperature of the lamp head can still soar to about 70°C. In use, one should pay attention to avoid burns; the other is to choose a suitable gear to ensure the balance between temperature and battery life.
Because I manually turned on the extremely bright gear twice in the middle, the extremely bright battery life of the MK34II exceeded the 1 hour and 20 minutes given in the manual. Take out the battery, the voltage is about 2.8V, there is no over-discharge, and the circuit performance is good.
In addition, the MK34II has no direct charging function, the waterproof ring at the root of the thread has good sealing performance, and the lamp head is assembled and relatively fine, reaching the highest waterproof capability of IPX8 electronic products, and it can work normally under 2 meters of water, and it is not a problem for daily use.
Distinctive features, play the light to the extreme
MANKER MK34II has a distinctive appearance, unconventional oxidation color, simple and clear UI logic, extremely compact body, comfortable holding feeling, and relatively long-lasting battery life. It is currently an excellent large floodlight flashlight product. , it is very convenient and practical for both outdoor and home.
The most important thing is: to be bright, to be able to scan the mountains; to be dark, to be able to shine like a spark, suitable for use in various dark environments, what you hold in your hand is not only a lighting tool, but also a confidence to overcome the night. source.
