Cree LEDs are commonly used in a wide range of lighting applications. Their products are trusted by lighting professionals and have gained a strong reputation for quality and performance. The choice of color temperature depends on the specific lighting application and personal preferences. The InfiniStar 275 uses a smooth reflector. Unlike the textured surface of an orange peel reflector, a smooth reflector has a polished, mirror-like surface.

The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The InfiniStar 275 has mechanical switch. Mechanical switches often offer tactile feedback, allowing users to feel a distinct click or resistance when the switch is pressed. This feedback helps users confirm that the switch has been activated or deactivated, providing a reassuring sense of control and awareness. With a rear switch of InfiniStar 275 flashlight, the operation of the flashlight is often straightforward and easy to grasp. A simple press or click of the rear switch turns the flashlight on or off, eliminating the need for complex button combinations or multi-step processes.

Intensity1000 cd
Throw63 m
CD/LM factor3.64

If you mainly need a flashlight for basic tasks like finding keys, navigating in dimly lit areas, or occasional use around the house, 275 lm can be adequate. 1000 cd can provide a reasonable level of luminous intensity for many everyday lighting tasks. The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 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. Well-focused spot beams can be over 100 cd/lm, tactical flashlights are typically between 20-100 cd/lm, and work lights are less than 10 cd/lm. In some cases, a flashlight with a higher CRI may offer a more natural and pleasant viewing experience, as it can better reveal the true colors of the surroundings. This can be advantageous when using a flashlight for extended periods or in situations where visual comfort is desired. The InfiniStar 275 with a CRI of 90 is beneficial in everyday use where accurate color perception enhances the overall visual experience. It can make colors appear more vibrant, natural, and distinguishable, allowing for a more immersive and enjoyable lighting environment.
