Acebeam H15 2500lm In-depth review, Pros and Cons
The Acebeam H15 (H15) released in 2018. It uses Cree XHP70.2 LED, OP reflector and 1 x 18650 Li-Ion battery. The powerful emitter in this headlamp provides up to 2500 lm output, 4540 cd intensity, and a beam distance of 135 m.
The H15 headlamp is designed to provide hands-free illumination, allowing the user to have both hands available for other tasks while having a focused light source. This light has 5 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. It has a strobe function, which is one of the most effective self defense tools available.

Body diameter | 20.8 mm |
Head diameter | 24 mm |
Material | aluminium alloy with HAIII hard-anodized finish |
Colors | black sand |
The H15 is small, compact, and designed for ultra-portability. The length of a flashlight can also impact its balance and weight distribution. A well-balanced flashlight, where the weight is evenly distributed, can be more comfortable to hold for longer periods and reduce hand fatigue. The aluminium body of H15 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 H15 flashlight is available in assorted colors: black, sand.
System
Emitter | Cree XHP70.2 LED |

Color temperature | 5000 K, 6500 K |
Reflector | OP |
Lens | toughtened AR coated glass |
Switch | electronic front, rotary front |
The emitter of H15 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 orange peel reflector of H15 is designed to improve the beam characteristics of the flashlight by diffusing the light emitted from the light source.
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 H15 flashlight. The multiple switch configuration on the H15 flashlight can be a useful option, providing additional versatility and convenience in operating the flashlight. The H15 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.
Performance
Flux | 2500 lm |
---|---|
Intensity | 4540 cd |
Throw | 135 m |
CD/LM factor | 1.82 |
With 2500 lm, the H15 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 4540 cd, the H15 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.
Software
Modes | 5 modes |
---|---|
Mode memory | no |
Ramping mode | no |
Strobe | yes |
SOS/Beacon | yes |
Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The H15 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.
Features
Battery | 1 x 18650 Li-Ion battery |

Battery indicator | no |
Charger port | no |
LVP | yes |
Thermal regulation | yes |
Protection | IPx8 |
AUX LEDs | no |
Magnetic | no |
The Acebeam H15 flashlight is powered by 1 x 18650 Li-Ion battery. The H15 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 "8" in the IPx8 rating indicates the highest level of protection against water ingress.
Accessories
Package contents | 18650 battery 2 x spare o-rings clip headband |

It comes with a battery. The battery must be fully charged before you first use your H15. The clip provides flexibility in how you carry your 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 Acebeam H15 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.
