Materialaluminium alloy with HAIII hard-anodized finish

This 213 g flashlight is not excessively heavy, but it is noticeably heavier than the average weight for handheld flashlights. 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 TM03 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery.

The body of TM03 flashlight treated with a Type III hard-anodized, anti-abrasive finish. The TM03 flashlight is offered in a stylish black color.

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. The orange peel reflector of TM03 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 TM03 flashlight. The multiple switch configuration on the TM03 flashlight can be a useful option, providing additional versatility and convenience in operating the flashlight. The TM03 has mechanical switch. Mechanical switches are known for their durability and reliability. They are typically built with robust construction, making them resistant to wear and tear, and capable of enduring various environmental conditions. The placement of the rear switch at the end of the TM03 flashlight facilitates a secure forward grip. This grip allows for better control and handling of the flashlight, especially in situations where precision and stability are important.


Flux2800 lm
Intensity21000 cd
Throw290 m
CD/LM factor7.5

With 2800 lm, the TM03 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 TM03 flashlight with 21000 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.


Modes4 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 TM03 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. Strobe mode on TM03 flashlight produces a rapid, repeated flashing of light. It can be used for signaling purposes, self-defense, or attracting attention in emergency situations.

The TM03 flashlight utilizes 1 x special 18650 Li-Ion battery as its power source. The TM03 has a battery indicator. A battery indicator is a feature that provides information about the remaining power level of the flashlight's battery. It helps users monitor the battery status and estimate how much runtime they have left before the battery needs to be recharged or replaced. The TM03 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 rating indicates the highest level of protection against water ingress.


Package contents18650 battery
spare o-ring

With an included battery you can immediately use the flashlight for your desired applications, saving time and allowing you to focus on your tasks or activities.
