HAIII coating is widely used in the flashlight industry due to its durability, corrosion resistance, improved grip, and aesthetic appeal. This flashlight features a captivating black color.
System
| Emitter | 3 x Cree XM-L2 LEDs |
|---|---|
| Color temperature | 6500 K |
| Reflector | SMO |
| Lens | AR coated glass |
| Switch | mechanical 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 DV55 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 on the lens maximizes light transmission, making the flashlight more effective in darker environments. The DV55 has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness.
Performance
| Flux | 3000 lm |
|---|---|
| Intensity | 22500 cd |
| Throw | 300 m |
| CD/LM factor | 7.5 |
The 3000 lm output of DV55 provides greater versatility, as you can adjust the brightness levels to suit different lighting needs. The DV55 flashlight with 22500 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. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.
