Cree is widely regarded as a reputable LED manufacturer and has a track record of delivering high-quality and innovative lighting solutions. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The 311 has an OP reflector. The advantage of the orange peel (OP) reflector is that it can minimize glare and reduce eye strain, as the diffused light is gentler on the eyes compared to a focused, concentrated beam.

The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments. The 311 has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness. The rear switch of 311 is typically operated with the thumb or finger, making it easily accessible and convenient to use. The positioning of the switch at the rear of the flashlight allows for natural and intuitive operation, particularly in one-handed scenarios.
