The aluminium body of the M20 has a reputation for being durable and strong. It offers excellent resistance to impacts, scratches, and corrosion. Flashlight makers widely use HAIII coating. It is durable, resists corrosion, and improves grip. It also looks good. Factors can influence the color choice of the flashlight body.

Cree is widely regarded as a reputable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The M20 has an orange peel (OP) textured reflector. Orange peel reflectors have smoother beams. The coating is thin and applied to the lens surface. It cuts reflections and boosts light transmission.

150 lm can provide a decent amount of brightness and be suitable for many everyday tasks. 628 cd can make things quite bright. It's enough for many everyday tasks. The throw is the distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) measures a flashlight's beam intensity. It compares this to its total luminous flux or output.
