A Brief Review Of Fenix LD32 UVC Flashlight

As an EDC portable product, a flashlight with integrated ultraviolet disinfection function is very attractive to me in this special era. So why did UVC LED choose to be integrated on the flashlight, and what is the significance?

Because the flashlight is a necessary tool for family emergency kits and survival maniacs, it is the primary equipment for disaster prevention and mitigation in families, and the portability of the flashlight is incomparable to other ultraviolet disinfection lamps. The experience at the beginning of the year forced me to take a long view. The appearance of Fenix LD32 UVC flashlight has completely changed the way of disinfection in the past.

At present, although COVID-19 pandemic prevention and control measures have been adjusted, personal protection can not be relaxed. On the one hand, we should adjust our mentality and prepare for the possibility of being infected. On the other hand, we should insist on taking necessary protective measures and be the first responsible person for our health. Every time we go shopping, we should use new masks. When we come back, we put our clothes outside the door and spray alcohol to kill them. We should change our masks and wash our hands and face. Because these protective measures are not only effective for the new coronavirus, but also for other common respiratory infectious diseases.

Every time I go out with new consumption is very fast, this situation may not persist for too long, all kinds of cleaning and exposure to recycle disposable products several times. At this time, the street drugstore was completely out of stock, and recycling was the only way. At that time, I was most worried about the incomplete disinfection. After the mask was cleaned, the protective ability was greatly reduced. Now the disinfection method has become simpler.

It's a disinfection lamp and a flashlight. Will there be a short board? The emergence of any novelty requires a process of adaptation. The function of the flashlight is lighting. When I didn't see the real thing, I had two big questions. Now I can finally reveal them slowly. LD32 UVC flashlight light color is perfect, using a star lamp bead Cree XHP 35 HI, compared to the previous series of SST40 lamp beads more exciting, in terms of light color, presumably those obsessive-compulsive disorder patients have nothing to choose this time.

Sophisticated optical system, equipped with the LD32 UVC flashlight with a jelly-free core, is far and wide. Under the reflection of the beautiful orange peel eyes, the medium-range projection effect is believed not to be bad.

Long-range effect, extremely bright 1200 lumens of projection, uniform transition between the main and auxiliary spots, satisfactory paving effect in the short and medium range, the whole road is covered by light, the farthest main spot illuminates a whole wall, the overall performance is not bad, the day has gradually entered the late autumn mountain mist.

The Fenix LD32 UVC flashlight is made of 6061-T6 aluminum alloy, which is subject to the three-level anti-wear treatment of the military regulation hard oxygen. The basic characteristics of the military regulation hard oxygen are dark, wear-resistant, corrosion-resistant, scratch-resistant and scratch-resistant, and it is also the mainstream configuration. Phoenix classic tube body super dense texture, has the characteristics of anti-skid, perspiration and heat dissipation, is also an important element of Feiji flashlight, brand recognition is very high. The flashlight supports handstand use, with a wide range of application scenarios, outdoor and home can be the first choice for compact EDC.

The neck of the flashlight is equipped with multi-functional metal buttons. The buttons support the power inquiry function. Different power will be distinguished by different colors and flashes. Similar buttons occupy a very high proportion in the Fenix flashlight. Neck design is also quite special, processing four planes to play a certain anti-roll function, and processing three fins between the planes to enhance the heat dissipation function of the head. The anti-scald triangle logo on the head reminds us that we must not underestimate the existence of violence.

The back of the switch button is the UVC LED, ultraviolet emission window, a very strange structural design, the protective cover supports bare hand rotation, and there is a small hole that should be able to wear a rope to prevent loss, similar flashlights that support UVC LED to produce ultraviolet disinfection are rare, and almost rare on sale. The whole UVC LED flashlight market seems a little lonely.

Very mini metal protective cover, with waterproof O-rings at the root, supporting IP68 protection, rain and dust can not invade, the cap is very small and requires fine operation, the difficulty is 1star, I feel that it is not difficult, but the size is relatively small, it is more convenient to operate with bare hands, and the rotation damping is moderate. When the protective cover is installed in place, the possibility of loss is very small, and it is not excluded that the hand shakes off the ground outdoors.

Using Liteon high-power UV LED, UVC output power of 10 mW and wavelength of 270 nm can effectively disinfect and sterilize. The UVC LED luminous group has two luminous chips in total, the ultraviolet chips emit ultraviolet light with a wavelength of 270 nanometers, the ultraviolet light is pure in wavelength and has no blue-purple stray light, and the ultraviolet light is invisible to the naked eye, so that a user may think that the product is not started to work, so that the user may look directly at the LEDs with eyes, and the health of the user is affected by accidental injury caused by the ultraviolet rays. Therefore, a blue LED is added to the design as an indicator light to avoid unnecessary damage to the glasses and the body.

The tail of the flashlight is designed with flat ear protectors. The flashlight supports handstand use. Outdoor emergency lighting at home is more friendly. Two oval rope holes are processed on each side of the ear protector. The rope holes on the edge of the ear protector are CNC chamfered, and the edge is smooth and smooth.

For UV disinfection, screw the protective cover to the tail base to prevent loss. This design is very good. The designer should add chicken legs, otherwise it will be very troublesome to lose the protective cover. This must be praised.

The LD32 UVC flashlight is equipped with an orange peel light cup, and the lens is made of coated tempered glass, which emits a faint purple light under the side light. Small straight flashlight choice of orange peel cup is less and less, manufacturers may focus on different, smooth cup long-range slightly stronger orange peel cup floodlight is softer, short-range floodlight is better. In terms of actual experience, the orange peel cup is more comfortable than the light cup in the use of close-range lighting, and the ultra-long range basically does not consider the small straight.

Volume advantage, the size of the flashlight is only the size of the palm, the six axial grooves of the tube body are matched with the transverse texture, and the whole grip feel and anti-skid performance are very good. In terms of visual perception, the layers are distinct and the textures are interlaced, and the fine three-dimensional sense is more intense. In the actual operation of wearing gloves, the fine texture provides enough friction for the hands, which is not easy to get rid of when using, and the tail can wear a matching hand rope to save more worry for outdoor activities.

LD32 UVC flashlight adopts 18650 tip customized battery core, which is safer to use battery with protection circuit, and can reduce the risk of abnormal short circuit.

The internal processing of the flashlight is fine, the materials used are quite powerful, the tail negative spring is strong and powerful, and the gold-plated treatment effectively reduces the contact resistance.

The Fenix LD32 UVC flashlight is a standard small straight flashlight with a slightly larger head, a diameter of 25.4mm, a thin body of 22.5mm, a total length of 121mm, and a total combat weight of 119 G. The body is designed in a lightweight style. It is very convenient and practical to carry it with you for daily commuting. It is only slightly larger than the AA cylinder, and the size control is very good. It has a very high similarity with the tactical small straight PD36R. It suddenly occurred to me that if we add a tail press to the Fenix LD32 UVC flashlight, we can change the tactical flashlight in seconds. In other words, we should develop a module flashlight. Different combinations become different products, and the playability is greatly improved. Of course, this may only be suitable for very small players.

The racetrack-type switch on both sides of the neck is the exclusive switch to activate the ultraviolet sterilization function, and the central sinking design of the switch is more suitable for fingers.

Due to the danger of ultraviolet UVC light, attention should be paid to prevent exposure to human and animals during operation. A triple protection design is added to the opening of the ultraviolet light, the first physical protection uses a safety protection cover, the second protection double button is pressed to start at the same time, and the third time limit is 30 seconds to force the ultraviolet lamp to close, so that the ultraviolet lamp can be prevented from causing harm to the human body due to accidental touch. Open the protective cover, press the double key to emit blue light. What really works is the invisible light above the blue light, which emits dim light. Sterilization is the most appropriate in the invisible. The light outlet is aimed at the disinfection object at close range to complete the disinfection and sterilization operation.

(UVC ultraviolet penetration is very weak, ordinary transparent glass, clothing, plastic, dust, etc. Can completely block, in order to avoid affecting the killing effect, so the Fenix R & D team did not add a lens in front of the ultraviolet led in the design.)

Bacteria and viruses are everywhere in life. Of course, miniaturized UVC LEDs are more flexible and easier to carry and operate than large ultraviolet lamps. The old ultraviolet mercury lamp products have the advantage of high light power, which is mainly suitable for sterilization and disinfection in large spaces, such as hospitals, school canteens and so on.

UVC LED has the advantages of fast startup, long service life, energy saving, etc. Integrated into the flashlight, the volume advantage is obvious, and it is handy to deal with small areas of sterilization and disinfection, such as commonly used mobile phones, keyboards, mice and so on. Bacterial breeding is very serious, and it is not easy to clean up the dirt. With the LD32 UVC flashlight, the disinfection operation is more relaxed and comfortable, which is a cool. The intensity of ultraviolet UCV will decay with the square of distance. For keyboard products with a slightly larger area, it is recommended to sterilize in different areas or increase the sterilization time to achieve good results.

Tableware disinfection should be applied in special scenarios, such as dining out, canteen and so on. In public places, all kinds of uncertain risks increase, especially the entrance of things, as the saying goes, diseases come from the mouth, coupled with unscientific dietary culture will often become incentives.

Now under the irradiation of LD32 UVC flashlight ultraviolet rays, it is believed that killing is safer and filtering performance is not easy to reduce. It is the most important thing to choose different killing schemes at different risk levels so as not to let the fish out of the net harm our health.

When disinfection and lighting become the norm, the flashlight's endurance is also very critical. Fenix comes standard with a 3400mAh 18650 battery with its own charging circuit. The only pity is that it uses Micro USB interface instead of the more convenient Type-C interface, which is almost the biggest disadvantage. When the power supply is connected for charging, there is a red reminder on the top, and it is easy to turn to the green light after charging.

It is relatively simple to charge the battery with its own charging circuit, without a separate charger, just connect the standard charging cable. The battery supports 5V1A input, and the measured input power is 4.1 W. It takes more than 3 hours to fully charge the battery. The charging speed is acceptable 18650. The charging rate is too high to affect the cycle life.

The flashlight supports IP 68 level protection, 6 levels of dust-proof and 8 levels of waterproof, 2 meters of water depth is easy to deal with, and the daily rainwater in streams and rivers does not affect the normal use. Operation logic of Fenix LD32 UVC flashlight: the flashlight has 4 constant light positions, which are 15 LM, 150 LM, 350 LM and 1200 ml respectively. Press the side button for a long time to enter the flash mode.

The long-range range is 20m/60m/90m/170m/respectively. Click the side button to switch circularly and press long to start the flash function. After shutdown, there is a memory gear. Take the highlight mode as an example, the official announcement lasts 4 hours and 45 minutes, and it is guaranteed to meet a certain period of outdoor activities.

Under the fog, the light projection effect of LD32 is more intense, like a sharp blade piercing the sky, and the divergence angle of the flashlight can be clearly seen. The divergence angle of the Fenix LD32 UVC flashlight is almost 65 degrees, which is slightly far away. The maximum range of 170 meters can be met in conventional application scenarios. It should be a relatively balanced flashlight as a whole.

Medium bright mode 150 lumens close illumination, the central spot left a clear image on the ground, the surrounding environment can also be seen, medium bright mode can meet daily use, walking the dog at night is no problem. When I see the medium and low brightness, I just want to say that the white is really white, without any ambiguity.

Extremely bright close illumination, the coverage of the secondary spot is very large, a large area of forest is covered by the spot, the brightness of the spot is relatively uniform.

1200 lumen long-range projection, the longest range of LD32 UVC flashlight is 170 meters, the light after the soft reflection of the orange peel cup is relatively uniform, especially the close-range spot is very symmetrical, and the foot is bright, even if the outdoor scene can still be a battle. The jelly-free core should be stronger in long-range projection, but the small straight-tube light cup is small, which can not fully reflect the strength of the Cree XHP 35 HI lamp bead, and the orange peel cup is slightly inadequate in long-range projection.

During the outdoor activities in autumn, I found the elves under the night. Hedgehogs are the third-class protected animals in the country. Hedgehogs in Heilongjiang belong to the second-class protected animals in the country. When they are frightened, their thorns stand up and roll up like thorn balls. Children are very happy to see them when they meet at night. Hedgehogs are slightly frightened when they are illuminated by 150 lumens in LD32. When they meet small animals, they must not look directly at their eyes with strong light, so as not to harm small animals. Protecting wildlife is also an important topic in outdoor activities.

Whether it is home life, study office or business travel, outdoor exploration LD32 UVC flashlight can bring different experiences, Sao Nian set out with your beloved small flashlight! Tips: On the question of whether UVC purple light can kill the novel coronavirus, here is a non-professional interpretation, and the level of knowledge is limited for reference only.

First of all, in terms of the characteristics of UVC LEDs that produce ultraviolet rays, UVC ultraviolet rays can effectively penetrate biological cell membranes and nuclei in a very short time, and begin to destroy bacterial DNA or RNA from the moment the irradiation is turned on. A 30-second cycle of irradiation can kill a variety of bacteria, that is to say, ultraviolet rays also have an effect on special viruses. The killing effect is closely related to the irradiation intensity.

In addition, the wrong use of ultraviolet rays is very harmful to the human body, children should not use, scientific and rational use has become very important, remember.
