The heavier flashlight may be more tiring to hold for extended periods or less suitable for activities that require lightweight portability. It's important to consider the length of the flashlight to ensure it fits comfortably in your desired carrying method. Aluminium is a lightweight material, which is beneficial for G30 flashlight. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. This flashlight comes in a sleek black color option.

Cree is widely regarded as a reputable LED manufacturer. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The orange peel (OP) reflector is a specific type of reflector commonly used in flashlights. The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The G30 uses multiple switches. Depending on the placement and design of the switches, a multiple switch configuration can allow for one-handed operation.

The electronic switches may have a higher likelihood of standby drain compared to mechanical switches. Rear switches are commonly found on tactical flashlights designed for law enforcement, military, and self-defense purposes.

The power source of the G30 flashlight is 3 x 18650 Li-Ion batteries, providing reliable and long-lasting energy for optimal performance. A battery indicator is a feature that provides information about the remaining power level of the flashlight's battery. The G30 doesn't have charger port. LVP (Low Voltage Protection) is designed to protect the battery from being over-discharged, which can lead to reduced battery life or even permanent damage.

The thermal protection feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety. The flashlight with IPx8 rating can withstand being submerged in water beyond 1 meter for a prolonged period, typically specified by the manufacturer.
