Lighting professionals trust Cree LEDs. Cree LEDs have gained a strong reputation for quality and performance. The color temperature choice depends on the light's use and personal taste. The SRT6i uses a smooth reflector. A smooth reflector is different from an orange peel reflector. It has a polished, mirror-like surface. The AR coating on the lens maximizes light transmission. This makes the flashlight more effective in darker environments.

The SRT6i uses multiple switches. The switches' placement and design determine this. They allow for one-handed operation. Mechanical switches often offer tactile feedback. Users can feel a distinct click or resistance when they press the switch. A simple press or click of the rear switch turns the flashlight on or off. This removes the need for complex button combinations or multi-step processes.
