There are 3 features that make FOXFURY unique:
1. Peripheral Vision: FOXFURY provides
up to 60 (18 m) feet of peripheral/panoramic vision.
2. Photopic Lighting emission matches the
human eye perception of color intensity for each color in the spectrum.
The LEDs are chosen to provide more Green than Yellow, because our
eyes function in this way. The output is therefore a light output
that provides better color rendition to the human eye. This reduces
bleaching and washout, which is typical of too much light of the
wrong color (usually present in fluorescent lights).
3. Photopic Sensors respond to ambient lighting,
and to reflections as the human eye would, and automatically DIM
the lights accordingly. This is especially useful when involuntarily
looking at a reflection from a mirror type surface, or when two individuals,
each wearing the same device, look at one another. Photopic Sensors
are also useful in situations involving white smoke or snow.

| LEDs | |
|---|---|
| LEDs are Light Emitting Diodes. LEDs provide the longest lifetime by far in comparison to other light sources, including halogen incandescents. One colored LED by itself lasts approximately 100,000 hours, meaning that if it were to be kept on 24 hours/7 days a week, it would last for 11.4 years! As a benefit of being more efficient, they produce a lower fraction of wasted heat output. | |
Should one LED break due to a fall, or if
a circuit shorts (though the board is designed to prevent
this), what will happen is that at most 4 LEDs will go out.
This is because the LEDs are circuited in groups of 4 in
the Signature Series, groups of 2 in the Pro Series, and
individually in the Performance Series. While the customer
can replace a broken LED, we recommend that you return the
product to the manufacturer to fix (as long as the product
is under warranty) to guarantee that the system will remain
waterproof. |
|
| Colored LEDs have an average life of 100,000 hours or 11.4 years of constant use. White LEDs have an average life of 20,000 hours or 2.3 years of constant use. Luxeon Star LEDs have an average life of 6 years or 55,000+ hours of constant usage. Therefore, it is very unlikely that the LED’s will need to be replaced. | |
| RATINGS | |
|---|---|
| While no specific requirements are established by NFPA (National Fire Protection Agency), all components of the Fire Fighter version can withstand higher temperatures than normal. Silicone high-temperature cable, synthetic rubber head strap, and closed cell neoprene face foam are the visible changes over the standard Outdoor Light. | |
The FoxFury Intrinsically Safe Signature Editions are designed with a double "O"-Ring seal on the battery pack which is intended to render the product Intrinsically safe, or explosion proof. The battery pack also contains a fuse and fusible resistor. This means that the act of using the light, including turning it on and off will not cause any explosions in hazardous gas filled environments, for example. FoxFury has recieved formal UL 913 approval for these products. Please see Intrinsically Safe products. |
|
| Different levels of Waterproofing are
available. Signature models are configured as follows: Outdoor, Low Vision - One coat Polyurethane cover, Water-Resistant Fire, Work & Safety, Tactical, Fire - Two coats Polyurethane cover, Waterproof – 20 ft. SCUBA - Three coats Polyurethane cover, Waterproof – 150 ft. |

This feature is so unique to the industry that it was granted a US Patent (US Patent No 6,966,668). (Photopic) Sensors placed above each eye match the Human eye response to light. They respond similar to the human eye’s pupils and do so faster than our human eyes can respond. Therefore, when an unexpected bright reflection from a: mirror, snow, water… is sensed, the sensors respond by dimming the lights (independently above each eye) to reduce eye discomfort to a minimum. The Human eye is sensitive to light over a very large range (10,000,000 times) of light intensity. This allows us to adapt to very strong sunlight, or a very dark room. Keeping with the idea of hands-free operation, the sensors can shutdown the LEDs completely when the ambient light illumination is sufficient, saving battery power for when it is needed…in the dark of the night |

Monocolored light involves a narrow spectrum of light. The result is a light tailor-made for the specific application. Our Forensic, Hunting, Tactical and Desert editons make use of monocolored light. All other editions are polycolored.

There are LED flashlights and headlamps on the market that run with a simple constant light output (constant power). The main problem with these flashlights appear at the end-of-life for the batteries, they shut-off abruptly without warning of impending failure and they have short battery life-times. For most of our users, an abrupt shut-off would be a poor design choice with results ranging from a major inconvenience to severe injury. There are LED flashlights that use a simple ballast resistor that makes the light output react like a standard incandescent flashlight does - it slowly dims over time. It’s not as efficient, but a lot safer and gives you some feedback, allowing you time to plan ahead. FoxFury’s Performance Series uses this design approach. The Intrinsically Safe Signature unit also uses this style to meet UL’s safety certification requirements. For all other Signature Series models, we chose a modified power-curve approach, it works somewhat like a constant power lamp. But it decreases light output along with the battery voltage until the Reserve mode threshold is reached. At this point, the headlamp shuts down half of the LEDs to conserve power, and give you a heads up that it is time to change the batteries soon. But if you can’t put a fresh set of batteries, then it will continue to slowly decrease the light output (power usage rate) well into the Emergency Mode. |

The energy efficiency of FoxFury’s custom designs: Signature Series: Starts at 92% and decreases to 82% efficiency as the batteries discharge. Efficiency is defined as the percentage of the electrons released by the batteries transferred to the LEDs, which converts them into photons viewed by the human eye. Most lights are only 65% effective in this area. Performance Series: Starts at 60% and increases to 80% efficiency as the batteries discharge. Efficiency is defined as the percentage of the electrons released by the batteries transferred to the LEDs, which converts them into photons viewed by the human eye. Most lights are only 65% effective in this area. |

This feature is so unique to the industry that it was granted a US Patent (US Patent No 6,966,668). Most lights provide a conical light output which illuminates a subject in the form of a circle. These circular light spots are typically in the range of twelve degrees or less as they exit a standard incandescent bulb & reflector combination. Accordingly, anyone with a flashlight, or an equivalent headlamp, will have to move the light around in order to see the surrounding area, where FoxFury’s Signature and Performance editions will cast a much larger light pattern that is basically rectangular in shape (elongated oval). This allows the wearer to simply move their eyes, not their heads. Separate from the obvious advantages, such a time savings can prove critical in dangerous situations, like fire fighting. |

The Figures below show the different colors of the spectrum, and the human eye’s ability to see them. It shows that our eyes respond to colors that are mainly green, and least at the extremes of red and blue. If a light source matches the output of each color to the curve shown, then that light will be optimal for the human eye. In other words, no light or energy is wasted because we cannot see it. A light with too much energy beyond red is a real waste of energy, because we can't see it, but we call them incandescent bulbs. A light with too much energy beyond blue would also be a waste of energy, because we can’t see it, so we coat the insides with phosphors to change the emitted wavelengths to those we can see better- the basis of a typical fluorescent lamp. A light source with too little green will render less than optimal images and colors (i.e. typical of parking lot lights - that are pink or yellow). White LED's are similar to fluorescent lamps
in that the light source itself is a specific wavelength
that is not too useful to the human eye (a deep blue). However,
by adding phosphors over it, combined emitted spectrum of
light is broad and continuous, which we perceive as white
light.
