The 99 g flashlight may not provide the same level of brightness or features as larger models. The length of a flashlight can affect how it feels in your hand and how you can grip and maneuver it. The aluminium bodies can be anodized, providing a protective layer and a wide range of color options for flashlight bodies. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. This flashlight features a captivating black color.

Switchelectronic side

Luminus has established a positive reputation as a reliable LED manufacturer. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches.

CD/LM factor2.5
CRI70

With 4000 lm, the IF25A 6500K flashlight will provide an exceptionally bright and powerful beam of light. With 10000 cd, the IF25A 6500K flashlight provides a noticeably brighter and more intense beam of light. The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output.

If accurate color representation is a priority for your specific needs, a flashlight with a CRI of 90 or above is highly recommended. A CRI of 70 can be sufficient for everyday use, such as outdoor activities, household tasks, or emergency situations.
