Luminus has established a positive reputation as a reliable LED manufacturer. Warm, white light is generally more comfortable. It's also less harsh on the eyes than cool, white light. The SMO's main job is to focus and project light from the source. It does this into a defined beam pattern. The coating is thin and applied to the lens surface. It cuts reflections and boosts light transmission. The electronic switches may have a higher chance of standby drain.

The TM39 flashlight has 5200 lm. It will provide an exceptionally bright and powerful beam of light. These flashlights have very high intensity. They need lots of power and make a lot of heat, this is because they have high energy output. 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.
Software, user interface, modes

A flashlight's modes are different output settings or brightness levels. They can be chosen to meet different needs and preferences. The flashlight has mode memory. It remembers the mode you were using when the light was last turned off. It stays in that mode when you turn it on again. The TM39 is tactical strobe ready. The strobe light is disorienting to the person it is aimed at, this makes it hard for them to concentrate. The SOS flashes Morse code so you can signal for help when needed.
