First, the appearance of details

In addition to the natcol HC33 L lamp, there is also a new NITECORE NL1835HP high-discharge, low-temperature battery.

The main black and yellow color of the box is the style of the Knight Cole brand. The 5-year warranty in the upper right corner is the brand's commitment to quality. Several aspects of the cartridge are briefly described.

Standard

This evaluation also included the NL1829LTHP 3.6V 10.44Wh 2900mAh 186501 high-discharge, low-temperature battery, which was additionally supplied by the manufacturer. It was specifically designed for low-temperature environments, greatly improved the cold resistance of ordinary batteries, and achieved low temperature resistance of minus 40°C. It is used in various harsh environments such as high altitude and low temperature. Once again, the discharge current of the battery is increased to a new level, and the current output reaches 8A, which perfectly meets the needs of high-performance electronic equipment. By the way, the HC33 can only reach 1,800 lumens using a battery with a discharge capacity greater than 8A.

The HC33 is of medium build. After measuring 106.0mm, the length and width of the barrel are 25mm and 24mm, respectively. The diameter of the tail cap is 24mm, the net weight is 50.9g, and the combat weight is 97.5g (without holding clips).
















The HC33 is made entirely of aerospace grade aluminum alloys, except for a small amount of stainless steel. The surface is hard-oxidized by the military regulations and the third grade, to increase certain resistance to operation, has a certain degree of wear and scratch resistance, generally a slight bump will not have a big impact.

The key setting position is at the top of the lamp head, and the soft rubber keys are covered with anti-slip particles and the hand feels better. The stainless steel pressure ring is provided with two grooves, which is about 2mm above the keys, so as to avoid accidental knocking. Even wearing gloves in winter is still convenient.

HC33 adopts the XHP35 HD LED from CREE, which is equipped with a large-current discharge battery and can guarantee the maximum output of 1800 lumens. The outer ring of stainless steel pressure ring can increase the head protection, can effectively protect the lens from falling directly from the impact, the pressure ring is set with five grooves, convenient hands-on ability users to explore or replace parts. The cylinder's serial number is printed on the lower side, and the laser print type and CE safety mark are printed on the left and right sides respectively.

Double-coated AR tempered glass, glossy reflector, to ensure a certain long-range capability, while the efficiency of high light efficiency, tempered glass also plays a role in protection of the LED, in spite of the ordinary bumper.

Four heat sinks form five deep and wide heat sinks, occupy about half the volume of the head, maximize the heat dissipation area and reduce the weight, plus Knightel's unique built-in ATR high temperature control module, when the temperature is at a certain value At the time, it has automatic adjustment gears to ensure its longer use and longer service life.

The HC33 comes standard with clips that can be freely disassembled according to your needs.

The barrel is full of knurled blocks, and each of the small blocks has three tangents. The grip feels better, and the effect of sweating is hot when the weather is hot.

Elastic wide-weave headlights with a brand logo on the front, with distinctive brand features, with two adjustment buckles to use. The head lamp holder is made of soft rubber material and can be easily inserted into the torch. Adjustable range is extremely large, even if you wear a velvet cap in winter, you can still wear it easily.


The bottom of the tail cover is flat and can be easily inverted. In addition, the brand logo and official website address are printed, and there are strong magnets inside, which can be freely adsorbed on iron objects and free hands. In the next test, the magnetic force is large, even if the sucking side sucks. The only regret is that the internal magnet looks like it cannot be removed. It seems to be stuck.







The tail cover is also knurled one week, and the tail cover is unscrew. Visible inside the battery compartment is a bag of desiccant, the negative electrode is gold-plated spring, the end face is conductive, rectangular thread, the tube head can also be unscrewed, the positive electrode plated copper column can be clearly seen, so it supports the flat head 18650 Battery, anti-reverse design.





The HC33 tube body can be interchanged before and after, and it can still light normally.


Second, simple test

operating:

In the closed state, press and hold the switch for 0.6s to open, otherwise close.

2.HC33 high-end 1800 lumen indoor wind test

Indoor wind-free environment test, room temperature around 15 degrees Celsius, using NL1829LTHP 3.6V 10.44Wh 2900mAh 186501 high-discharge low temperature battery full test, the battery voltage is 4.185V. The illuminance meter was used to measure the illuminance of the HC33 at a distance of one meter. A set of values ​​was recorded every 6 seconds. A total of 1900 data were automatically recorded. Open an extremely bright 1800 lumens and start the test.



At first, the illuminance at one meter distance is 8090lux, and the brightness of 1800 lumens is released. It needs to release a great amount of heat. Affected by the ATR intelligent temperature control module, the brightness is automatically adjusted to achieve the best working condition. That is to 137 sets of data that is about 14 minutes to complete the downshift process, and then tend to be stable about 2500lux output.

After the 1900 data test was completed, the flashlight was still on. Remove the battery and measure the battery voltage to 3.128V.

3, HC33 waterproof test

HC33 protection class IP68, 2 meters underwater, that is, dust level 6, completely prevent the entry of dust, waterproof grade 8, under a certain pressure for a long time soaking. Only waterproof test is done here. Put the flashlight underwater in a 30cm vase, and it can still operate normally in water. Take out the flashlight after half an hour. No water stains are found inside the barrel head and in the battery compartment. It can be seen that the button press ring and the light cup press ring and its rigorous, thread Waterproof ring tightly fit, waterproof test passed

Third, summary

The HC33 is equipped with the NL1829LTHP high-discharge and low-temperature battery, which can be said to have reached an unprecedented perfection. However, there are several points where improvements can be made:

1, the bottom of the barrel near the tail cover, a week smooth, too rigid, it seems like something less.

2, the manual mentioned that long press 0.6s, personal feeling so easy to cause misunderstanding, 0.6s itself is very short, it is better not to explain, direct short press.

3, if there is a hand rope hole on the tail cover, it will be excellent
