Lighting professionals trust Cree LEDs. Cree LEDs have gained a strong reputation for quality and performance. The color temperature choice depends on the light's use and personal taste. The smooth reflector creates a well-defined hotspot at the center. This hotspot provides a concentrated beam for long-range use. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.

The DL10 flashlight utilizes 1 x 18650 Li-Ion battery as its power source. The DL10 cannot charge batteries. You may need an external charger to keep your battery going. The flashlight detects when the battery's voltage has dropped to a certain level. Then, it reduces or cuts off the power. The DL10 has thermal protection feature. These mechanisms track and regulate the flashlight's temperature as it operates.

The "8" in the IPx8, depth 30 meters rating means the highest level of protection. It is against water ingress. This flashlight has an impressive impact resistance rating of 1 m. It is built to endure accidental drops or impacts. Auxiliary LEDs usually use less power than the main light source. For example, a white LED.

Accessories, package contents

Package contents2 x spare o-rings

When gripping the flashlight with the lanyard around your wrist, it gives a more secure hold. It also gives a more stable hold. Instead of searching for matching O-rings, having spare O-rings allows quick fixes.

According to the ANSI/NEMA FL1 Standard, we measure the performance of the DL10 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
