Simple and practical multi-mode flashlight
This is a small straight torch with current mainstream 21700 lithium battery, maximum luminous flux up to 1600LM, dual switch and dual mode. Of course, it has practical functions, clear lighting and low price. Come and have a look with me, the article simply refers to "C1".
Simple look, pragmatic style
Non-flashlight players are puzzled that some people spend hundreds or even thousands of yuan to buy a flashlight. There are plenty of users who can get free mail on 9.9! You are right, the torch is just to shine, but performance, technology, materials and life are also factors to be considered. Jusavee C1, Shanren, highlights the cost performance, which can be seen from the outer packing, and the main performance is marked out. It would be good to make a finger slot on the edge of the lid to hold the inner box.
Accessories also stand out in a practical and usable style. A flashlight, a manual, a nylon flashlight cover, a braided hand rope, and a spare sealing ring are all for you. If you need anything else, you can do it yourself.
For example, the battery holder will have ten or eight of them. C1 is very compatible with the battery. The flat head or pointed head is 21,700, and even a conversion cylinder for 18650 sets can be used, so you can save money by not buying batteries this time. In order to test, I bought a new Samsung 5000mAh 50E battery with the maximum discharge capacity of 10A.
C1 adopts the aluminum alloy used in most practical torches as the shell, which has the advantages of light, hard, good heat dissipation and not easy corrosion. The surface is made black by three-stage oxidation, anti-scratch and wear-resisting, and the shape of small straight barrel is slightly closed from the lamp neck to the tail, which breaks the single shape. The tube is smooth without any skid marks.
The C1 Samsung 50E battery weighs 154.1 grams and is 134mm in length. The maximum diameter is 29mm at the neck of the lamp, the barrel body and the lamp holder are 26.5mm in diameter, and the lamp holder is 21.2mm in diameter. It gives consideration to the portability of carrying and handheld operation.
C1 tail is equipped with a bidirectional clamp, that is, the lamp holder can be selected to clamp up or down, which can adapt to the habits of different users. The length, width and thickness of the clamping device are 75mm, 7mm and 4mm respectively. It can be used in various positions such as backpack, belt, pocket and hat brim. It is not easy to loosen and expands the carrying and using mode.
Lamp holder is more common one plane lamp holder, the appearance is quite simple and harmonious, lamp holder glass USES lilac coating film, improve light efficiency.
C1 cylinder body can be unscrewed only at the neck, and the lamp cap can be removed to achieve thermoelectric separation of the integrated silo, which is convenient for heat dissipation. It has a large area of gold-plated contact. The cylinder body adopts end-face conduction, which can be twisted slightly to realize complete power failure and avoid mis-opening.
The tail USES the gold-plated spring negative electric conduction, reduces the spring oxidation rust, brings the resistance increase, ensures the circuit voltage drop is small, the electric energy more application in the lamp bead light.
Double switch multi-mode, rich and practical functions
C1 circuit to realize the function is more, the tail, the lateral double switch design, the tail is black metal oxide key caps, this is the master switch, is responsible for the power, open on both sides have a u-shaped slot, is advantageous for the blind, refers to the slot side lugs on one side, there are two hand rope hole, can be tied hand rope, slightly higher than that of two side, but the key cap some influence flashlight upside down.
The side switch is located in the neck of the lamp. It is silver metal button with strong contrast color design. It is easy to take a glance to see where the switch is. Personally, I think it would be better to change it into a rubber cap and set a power indicator inside.
The main switch has a long key range, is a forward switch, the surface diameter reaches 14mm, and the feedback hand feeling is clear when the press is in place; Side press the switch surface diameter 9.6mm, the key path is short, mainly responsible for dimming shift gear. The accuracy of both switches is relatively high in actual use, and they are also relatively handy.
Press the tail main switch to open the circuit, C1 will turn on the memory brightness; Press the side switch again to adjust the brightness in the sequence of 15LM energy-saving, 150LM low-light, 350LM medium-light and 800LM high-light cycle. Combined with the long shot and flood light, C1's lighting can gradually expand the field of vision and improve the range with the increase of the brightness of the gear, which can give users light and confidence in the dark.
After starting the machine, double-click the side switch to directly enter the extremely bright 1600LM gear and return to the original gear. Click the three-click switch, then turn on the flash mode, and C1 will cycle in the three scintillation modes -- SOS -- beacon, and strike three again to launch the flash mode.
If you wake up in the middle of the night and are afraid of not adapting to the light or affecting the rest of your family, you can turn on the brightness of moonlight gear of 1LM. At this time, just press the side switch and press the main switch at the same time. The brightness of moonlight gear is low, so the human eye does not need to adapt in the dark, which is especially practical. Moreover, C1 adopts a constant current dimming circuit, with no stroboscopic brightness at each gear, which is more friendly to the protection of eyesight.
If the side switch is pressed continuously for more than 4 times in the starting state, the main light will flash twice, indicating that the current brightness lock function is entered. At this time, the switch will not change the gear. After the shutdown, the power on is still the locked gear, which is very practical for people with constant brightness lighting requirements. To unlock, you must tap the side switch four more times.
C1 has two dimming modes, gear and stepless. When switching on, press and hold the side switch for more than 5 seconds without releasing. The main light will flash twice to indicate successful switching.
The unidirectional travel of poleless dimming is about 5 seconds, and stepless adjustment from 1LM to 1600LM is completed. Once again, press and hold the side switch to realize reverse adjustment, which is very convenient. By stepless dimming, you can adjust the required lighting brightness according to your personal feeling, which solves the series limitation of fixed gear and is also a very practical function.
Far and wide is the light in the night
C1 USES Lumenus SST40 lamp bead, which is a small core lamp bead, with the orange reflective cup, plus coated glass, can bring more uniform irradiation effect, taking into account the lighting range and range.
Small straight torch is a practical torch, orange aluminum alloy reflective cup can make the light emitted by the lamp bead diffuse reflection, bring more comfortable, uniform lighting effect, a little distance away, can form a full glass of yellow water.
Since the light cup has a certain depth, about 20mm, C1 also has a good focusing effect. The main light spot of the wall can be seen to be perfectly round, while the scope of the secondary light spot is constantly too large, which has a clear boundary with the outside.
The luminous flux of 1600LM is relatively large for a small straight tube torch. C1's outgoing light is bright and concentrated, and the edge of the auxiliary spot forms an opening Angle of about 80°, which forms a bright lighting area at night.
C1 has a total of 1LM moonlight, 15LM energy saving, 150LM low light, 350LM weight, 800LM high light and 1600LM extremely bright. No effect can be taken from the moonlight 1LM photo. The other several gears are in the unlit field, and the lighting effect is shown in the dynamic figure below.
In fact, it is good to use the appropriate brightness outdoors, which will not consume power too quickly, but also keep the eyes from being exposed to too much sensitive gap environment. At this point, the use of the no-pole dimming mode, you can easily choose the appropriate brightness, and C1 light color is warm, medium brightness looks very comfortable.
When it comes to light color, C1 lighting also has good color rendering. Medium brightness, no matter warm color or cold color, can be well restored, with a color rendering index of about 85%.
In the dark outdoor environment, C1 can bring a large area of illumination with a transparent front and rear lighting effect. The paved floodlight is relatively uniform, ensuring that users can see the road ahead. It is very practical to carry out outdoor activities in the evening.
