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 aluminum bodies can be anodized. This adds a protective layer and a wide range of color options for flashlight bodies. HAIII is a specific anodizing process. It creates a thicker and harder oxide layer than regular anodizing. This flashlight features a captivating black color.

Luminus has established a positive reputation as a reliable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The AR coating on the lens maximizes light transmission. This makes the flashlight more effective in darker environments. The electronic switches may have a higher chance of standby drain.

The throw distance is the farthest distance the flashlight can light an object. Candela per lumen (cd/lm) measures a flashlight's beam intensity. It compares this to its total luminous flux or output. If accurate color is a priority for you, choose a flashlight with a CRI of 90 or above. A CRI of 70 can be enough for daily use. This includes outdoor activities, household tasks, and emergencies.
