Color temperature6500 K
Lenstoughtened AR coated glass
Switchelectronic side

The emitter of BLF GT4 manufactured by Cree, a US-based LED manufacturing company. Cree is a well-regarded LED manufacturer known for its high-quality products and innovation in the lighting industry. Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light. The BLF GT4 uses orange peel (OP) textured reflector. The orange peel (OP) reflector is a specific type of reflector commonly used in flashlights. It is named after its distinctive textured surface, which resembles the skin of an orange.

The AR coating of the lens helps to mitigate these reflections by altering the refractive index of the lens surface. The BLF GT4 utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.

Throw1370 m
CD/LM factor18.76

This high-lumen (25000 lm) flashlight may not always be necessary or practical for everyday use. 469100 cd represents an extraordinarily high level of brightness. 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.
