It can be more comfortable to hold for longer and reduce hand fatigue. 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.

Cree is widely regarded as a reputable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The advantage of the orange peel (OP) reflector is that it can minimize glare and reduce eye strain. The AR coating on the lens maximizes light transmission. This makes the flashlight more effective in darker environments. The E9R-G4 uses multiple switches. The switches' placement and design determine this. They allow for one-handed operation.

The electronic switches may have a higher chance of standby drain. Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. Rear switches are common on tactical flashlights. Law enforcement, military, and self-defense personnel use them.
