People often recognize Nichia LEDs for their quality. They are durable and follow industry standards. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources. 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.

Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. The rear switch of the PL21 Nichia is rugged and durable. It can withstand harsh conditions and repeated use.
