Nitecore DL20 1000lm In-depth review, Pros and Cons
The Nitecore DL20 (DL20) released in 2018. It uses Cree XP-L HI V3 LED, SMO reflector and 1 x 18650 Li-Ion battery. The powerful emitter in this diving light provides up to 1000 lm output, 12400 cd intensity, and a beam distance of 223 m.
This light has 2 + 2 modes of lighting. Lack of mode memory means you need to manually adjust the flashlight's settings each time you turn it on to get the desired mode. The strobe function of DL20 produces a high-frequency flashing light pattern that is designed to disorient or distract potential threats or aggressors.

Nitecore DL20 (DL20) specifications
|Head diameter||34 mm|
|Material||aluminium alloy with HAIII hard-anodized finish|
The 135.5 g flashlight is generally comfortable to hold for extended periods and easy to carry in pockets or bags. They are suitable for various applications such as camping, hiking, or emergency situations. A 120-gram flashlight strikes a good balance between functionality, convenience, and weight. The length of the DL20 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 DL20 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery. The HAIII process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. The DL20 flashlight is offered in a stylish black color.
|Emitter||Cree XP-L HI V3 LED|
|Color temperature||6500 K|
|Lens||toughtened AR coated glass|
Cree LEDs are commonly used in a wide range of lighting applications. Their products are trusted by lighting professionals and have gained a strong reputation for quality and performance. The choice of color temperature depends on the specific lighting application and personal preferences. With the smooth reflector of the DL20, the beam tends to have a well-defined hotspot at the center, which provides a concentrated beam of light for long-range applications.
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 DL20 flashlight. The DL20 has electronic switch. Some flashlights with electronic switches have programmable features that allow users to customize the behavior of the flashlight. This may include setting specific modes, configuring brightness levels, or enabling unique functions according to individual preferences.
With 1000 lm, the DL20 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. The DL20 flashlight with 12400 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.
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.
|Modes||2 + 2 modes|
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. Strobe mode on DL20 flashlight produces a rapid, repeated flashing of light. It can be used for signaling purposes, self-defense, or attracting attention in emergency situations.
|Battery||1 x 18650 Li-Ion battery|
|Protection||IPx8, depth 100 meters|
|Impact resistance||1 m|
The DL20 flashlight utilizes 1 x 18650 Li-Ion battery as its power source. The DL20 cannot charge batteries directly. You may need an external charger to keep your battery going. LVP (Low Voltage Protection) is designed to protect the battery from being over-discharged, which can lead to reduced battery life or even permanent damage. The built-in thermal control automatically adjusts brightness output to prevent overheating.
The "8" in the IPx8, depth 100 meters rating indicates the highest level of protection against water ingress. The impact resistance of a flashlight can vary depending on its design, construction, and intended use. It has auxiliary LEDs which make it really nice looking.
|Package contents||2 x spare o-rings|
The lanyard prevents accidental loss of the flashlight. 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 DL20 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.
