State of the Art LEDs
Cree is the industry leader in next generation Light Emitting Diode technology, producing LEDs that are capable of emitting hundreds, and in certain instances thousands of lumens.
Possessing a footprint no larger than a drop of water and consuming very little energy, Cree's diodes have a conservative lifespan of 50,000 hours and are virtually indestructible. All Nitecore torches are regularly updated with the latest Cree offering which ensures end users are always purchasing state-of-the-art.
The LED advantage
LED is an acronym for Light Emitting Diode – a special type of semiconductor that was initially used to replace standard lamps in early electronic equipment, later progressing to consumer electronics in the form of VCR and calculator displays. In the past decade, massive advances have been made in LED technology, with today’s high-power white tint LED’s commonly used in automotive/bicycle lighting, aviation, laptops and televisions, and even home lighting. LED technology is fast replacing older incandescent technologies.
Energy savings LED’s convert approximately 20% of their input power into light energy, compared to conventional incandescent bulbs which generally only convert about 2% of their input power into light. As a result, LED technology offers excellent energy savings over competing alternatives, making it a cost effective and environmentally-friendly solution for modern light-emitting devices.
The principle behind conventional incandescent technology is based on electrons travelling through a tungsten filament, causing the filament to generate temperatures of up to 2500 Celsius, with light energy merely a byproduct of this process. Due to this inherently inefficient design, incandescent bulbs rapidly deteriorate and burn out after about 1000 hours of use. LED’s, on the other hand, operate on an entirely different principle, and while they do require specialized components to achieve maximum brightness, a working lifespan up to 50,000 hours is possible, with a gradual fading of brightness rather than instant burn-out.
Due to the absence of a delicate filament and thin glass bulb, LEDs can withstand shock and vibration far beyond that tolerated by incandescent lamps making them ideal for rugged and demanding applications.
An incandescent bulb generally takes about 100-300 milliseconds to illuminate once activated, while an LED needs only a few nanoseconds, giving it a significant advantage in highly demanding applications.
