At the time of the fall of Mantang's rugged lotus, we ushered in the footsteps of the winter. The cold cream brought cold bones to the bones, but the cold could not knock back the heart of the waves. Hupenghuanyou searched for a path to the wild. Gradually shortening, it is inevitable that the night walk ahead, but the moonlight is difficult to find the long road ahead, headlights accompanied around, knowing the leisurely. Timely experience NITECORE naitekeer HC33 headlights, peace of mind. 
With the vigorous development of domestic and outdoor sports, equipment has begun to perform its duties. The choice of headlamps can no longer be extravagant, the right floodlight, and the excellent illumination distance in the exploration process are all I am an essential element of walking in the wild, and with the EDC concept in my heart, at the same time taking into account the convenience of carrying the headlights is also my focus. NITECORE Naitekeer HC33 just satisfies my day-to-day needs and taking care of outdoor hiking needs. 
It's a good thing to grind, and later got this headlight. The initial packaging is still Natcol's style. It's true that the millennium remains unchanged. The logo is very high. It's a bit regrettable that the package is not strong and it lacks Affiliation value. 
Unpacking and inserting plastic fixed headlights, with a clear view, the headlamps are placed in separate places, the security card manual covers the whole, accessories with a clamp, two waterproof ring, switch rubber protection. 
With the addition of clip accessories, this headlight application can achieve a 1+1>2 effect, and throwing off the headband can become an “EDC†concept lighting tool that can fully assume the portable character recognition. With a NL1829 LTHP low-temperature high-performance 18650 battery, even in the cold winter can guarantee the power output. 
After all, this is a headlight attribute of the lighting equipment, it is necessary to look from the headlights perspective, HC33 headband really not much, black headband above the gray and white stripes, there is always a dirty feeling, if you can join the luminous material I think it will change a lot. 
The HC33 headband still follows a one-sided adjustment. The top strap uses a detachable fastener. I have a head circumference of about 58cm. I keep the top strap at the centerline. I need to adjust the centerline to the top strap fastener to get the tightness. Satisfy outdoor use, hard fasteners are slightly stiff near the location. 
The connection position of the webbing and the lamp base, Knight Cole can be said to be the ultimate subtraction it, one design, soft plastic with a good extension performance, lamp pull-out assembly. 
As an "L" type headlight, the use of a wide range of compatibility has become a bright spot of attention. HC33 official stated that it can output up to 1800 lumens. Aluminum alloy is used as a barrel body. It achieves weight reduction and has strong performance while being used on the surface. The three-stage hard oxidation process is more resistant to use when used outdoors. 
The barrel body is a three-stage design. The lamp head uses a deep groove heat-dissipation streaking pattern. The control switch is located at the top. The internal thread fixes the rubber squeezing button. The squeezing button has a high degree of touch recognition. The tactile control rebound is obvious. . The middle section of the tail cover is embossed and has a good anti-slip effect. The three-section connection location of the swivel joints reinforces the sealing ring. The outdoor dust and water protection plays a certain protective role, and the lamp head airtightness can also bring certain help. 
The small lamp head has a large amount of energy. In order to improve safety and stability, the lamp head has built-in electronic anti-reverse connection and ATR advanced temperature control module, which maximizes the effective power output of the lamp bead in the safety range, ensuring the stable operation of the head lamp for a long time. Connotation I think we all know that 1800 lumens output heat conditions close to physical cooling can not guarantee safe lighting. 
Headlamp assembly position, the middle of the barrel set the corresponding groove, the edge of the groove is processed using chamfering process, the installation and removal of the match is very high, even after blinding wear can also be a good operation, lamp base plastic fastening Can meet the 180 degree irradiation angle adjustment. 
At present, many manufacturers have given headlights more features to choose from, and as I am more concerned about the nature of the headlights, a headlight is bound to have a wide area of ​​irradiation, HC33 reached a 100 ° effective irradiation area, in the outdoor this is Can fully meet the needs of use. 
This flooding perspective for the human eye can just match. Eyes, heads are not moving, the eyeballs can rotate, and the vision center can reach. Above 40 degrees, 50 degrees below, 55 degrees left and right. 
The HC33's five-speed illumination can meet the lighting requirements in different environments. Both low-light tents and high-light hiking camps can be used together. 
With long-distance exposure capability, outdoor can also be fully satisfied, and the light intensity in the visible range of human eyes can fully meet the needs of use. 
In terms of outdoor use, good light transmission performance is indispensable, especially in dense forest belts. Light transmission reflection is required to determine road conditions, and dead angles are minimized to see the road conditions. 
In outdoor use, strong hiking and sweat are inevitable. At this time, the headband's sweat-absorbent and breathable performance is very useful. The HC33 is woven with very good breathability, and water droplets can quickly absorb and spread. 
After the experience, there was an episode in the middle of the arrival of the headlights. The previously-arranged outdoor trekking circuit was canceled. After this period of time, my work had led to frequent business trips, and I was unable to complete the outdoor shooting experience. The quality of the report was greatly reduced, but from the shooting to the recent play Looking at this, this is a wide-angle lighting angle. Extremely bright gears are used for nearly one hour. The heat does not cause discomfort to the skin, but the outdoor temperature is about 5°C and is accompanied by light rain. Headlight waterproof performance has been tested, as the headlamps used at low temperatures with this battery can bring protection for the cold winter, and the removable design can also be assisted with camping lights in the outdoor camping help, but the magnetic attraction this function outdoor It is really not used, if you think of it as a multifunction lighting with both headlights and headlamp functions, then if you just use it as an outdoor headlight, I would like to use a little overkill.
