Body, materials, weight, colors

The SP40 is small, compact, and designed for ultra-portability. The best flashlight size depends on personal preference. It also depends on intended use and the specific features you want. The aluminium body of the SP40 has excellent thermal conductivity. This means it can effectively dissipate heat generated by the flashlight's components. The HAIII coating is uniform and attractive. It is often available in different colors, giving the flashlight a sleek, pro look. The SP40 flashlight presents an extensive selection of vibrant colors: black, desert tan.

System, LED, lens, reflector

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 designers of the SP40 incorporated an orange peel reflector to enhance the beam. It does this by diffusing the light from the light source. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. Some flashlights with electronic switches have programmable features. They allow users to customize the behavior of the flashlight.

Performance, flux, intensity, throw

With 1200 lm, the SP40 flashlight will offer a brighter and more powerful beam of light. The SP40 flashlight has 4620 cd. It provides a much brighter and more intense beam. The throw is the distance in meters at which the flashlight produces a light intensity of 0.25 lux. The candela per lumen (cd/lm) ratio can be used to determine if a flashlight has a spot or flood type beam.

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.
