Cree is widely regarded as a reputable LED manufacturer. Warm, white light is generally more comfortable. The designers of the U16 incorporated an orange peel reflector to enhance the beam. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. The electronic switches may have a higher chance of standby drain.

I love bushcraft and flashlights. I find joy in mastering wilderness survival skills and exploring the realm of illuminating gadgets. Bushcraft isn't just fun, it's a learning journey. I form a strong bond with nature. It's more than a hobby, it enriches me in practical and spiritual ways.
