The 150 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 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.
Aluminium is a lightweight material, which is beneficial for SD05 flashlight. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. This flashlight comes in a sleek black color option.

| Color temperature | 6500 K |
| Reflector | SMO |
| Lens | toughtened AR coated glass |
| Switch | electronic side |
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 SD05 uses a smooth reflector. Unlike the textured surface of an orange peel reflector, a smooth reflector has a polished, mirror-like surface.
The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The SD05 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.
Performance
| Flux | 2500 lm |
|---|---|
| Intensity | 15625 cd |
| Throw | 250 m |
| CD/LM factor | 6.25 |
The 2500 lm output of SD05 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The SD05 flashlight with 15625 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 distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 0.25 lux. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm.

The SD05 flashlight utilizes 1 x 26650 Li-Ion battery as its power source. The SD05 doesn't have charger port. A charger port is a designated connection point or interface where you can plug in a charger to recharge the flashlight's battery. 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 SD05 has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. This feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety. The SD05 flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.
