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. If long-range illumination and throw distance are the primary requirements, a flashlight with a smooth reflector may be more suitable. The AR coating on the lens maximizes light transmission, making the flashlight more effective in darker environments.

The TH20 Guardian 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. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. A simple press or click of the rear switch turns the flashlight on or off, eliminating the need for complex button combinations or multi-step processes.
