Seeknite SD05 specifications

Body, materials, weight, colors

The flashlight weighs 150 g. It is generally comfortable to hold for a long time, and it is also easy to carry in pockets or bags. A balanced flashlight has even weight. It can be more comfortable to hold for longer and reduce hand fatigue. Aluminium is a lightweight material, which is beneficial for SD05 flashlight. HAIII is a specific anodizing process. It creates a thicker and harder oxide layer than regular anodizing. This flashlight comes in a sleek black color option.

System, LED, lens, reflector

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 SD05 uses a smooth reflector. A smooth reflector is different from an orange peel reflector. It has a polished, mirror-like surface. The AR coating of the lens helps to reduce these reflections. It does this by changing the lens surface's refractive index. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.

Performance, flux, intensity, throw

The 2500 lm output of SD05 provides great flexibility. You can adjust the brightness to fit different needs. The SD05 flashlight has 15625 cd. It can light objects at greater distances. The throw distance is the farthest distance the flashlight can light an object. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam.

Features, battery, protections

The SD05 flashlight utilizes 1 x 26650 Li-Ion battery as its power source. The SD05 doesn't have charger port. LVP (Low Voltage Protection) is designed to protect the battery. It stops over-discharging, which can reduce battery life or cause permanent damage. The SD05 has thermal protection feature. These mechanisms track and regulate the flashlight's temperature as it operates. The flashlight has an IPx8 rating. It can withstand being submerged in water beyond 1 meter for a prolonged period. The manufacturer specifies this.

Accessories, package contents

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 SD05 flashlight 30 seconds after switching on the light. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
