Nitecore HC33 (HC33) specifications

Rated 3/5 based on 1229 user votes.

Headlamps consist of a light source attached to a headband, allowing users to wear them hands-free.


Weight51.2 g
Length105.3 mm
Head diameter25.5 mm
Materialaluminium alloy with HAIII hard-anodized finish

The HC33 is small, compact, and designed for ultra-portability. The length of the HC33 flashlight can affect its portability. A shorter flashlight is generally easier to carry in a pocket, bag, or pouch, making it more convenient for everyday use or when you're on the go. The aluminium body of HC33 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery.

HAIII coating is widely used in the flashlight industry due to its durability, corrosion resistance, improved grip, and aesthetic appeal. The HC33 flashlight is offered in a stylish black color.


EmitterCree XHP35 HD LED
Color temperature5000 K

The emitter of HC33 manufactured by Cree, a US-based LED manufacturing company. Cree is a well-regarded LED manufacturer known for its high-quality products and innovation in the lighting industry. Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light. The HC33 has a smooth reflector. The properly focused smooth reflector gives you a more cohesive hotspot and therefore throws better.

The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. This can increase the overall brightness and efficiency of the HC33 flashlight. The HC33 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.


Flux1800 lm
Intensity8750 cd
Throw187 m
CD/LM factor4.86

With 1800 lm, the HC33 flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. With 8750 cd, the HC33 flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances.

The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output. It quantifies the concentration of light emitted by the flashlight in relation to the total amount of light produced.


Modes5 modes

Ramping modeno

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The HC33 has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The HC33 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at which makes it difficult for them to concentrate. It has the SOS beacon function for an emergency situation. The SOS flashes Morse code so you can signal for help when needed. The SOS signal is recognized as an international distress call and is used to indicate an urgent need for assistance.

The Nitecore HC33 flashlight is powered by 1 x 18650 Li-Ion battery. The HC33 cannot charge batteries directly. You may need an external charger to keep your battery going. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary. The built-in thermal control automatically adjusts brightness output to prevent overheating.

The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the HC33 flashlight, is fully protected against the entry of dust and other solid objects. The "8" in the IP68 rating indicates the highest level of protection against water ingress. The HC33 is magnetic so that the flashlight can be attached to some metallic surfaces.


Package contents18650 battery
2 x spare o-rings
spare rubber cover

It comes with a battery. The battery must be fully charged before you first use your HC33. The clip is useful to keep the light secured in your pocket. Instead of searching for compatible O-rings or waiting for replacements to arrive, having spare O-rings readily available allows for convenient and immediate repairs or replacements.

The performance of the Nitecore HC33 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
