DID YOU KNOW that different levels of darkness, different environments, and different activities can benefit from either boosting or detuning select color wavelengths? The light spectra combination to best illuminate trail running, mountain climbing, spelunking, fishing, snowshoeing, or setting up camp may not necessarily be the same. You may have seen lamps with red LEDs and green, yellow, or other filters. If you tried these, you probably found minimal utility. 


PRECISION ILLUMINATION. We went an important step further to create the next evolution in full-color lighting: We designed our OWLSIGHT headlamp and LEGLIGHTS so that you can customize your lamp's spectra to meet your changing needs! In fact, our OWLSIGHT headlamp offers 12 selectable spectra and LEGLIGHTS offer 4 selectable spectral modes, all powered by Cyradiance technology.

You do not need to become an expert in Light Science

to enjoy the vision enhancing benefits of

Cyradiance technology and CYRAD systems,

but the more you know, the more you can see and do. 

The answer lies in Vision Science. We studied both how our eyes see at night and the properties of outdoor objects from many types of terrain we want or need to see better. We took spectral reflectivity data of more than 15,000 outdoor surfaces from many types of terrain. We utilized the sciences of human vision, studying how our eyes function in all levels of darkness. Then, we studied the light output of dozens of today's most popular flashlights and headlamps to determine what changes were needed for the next generation of wearable lighting.


We discovered that even the highest price headlamps and flashlights were weakest in the critically important cyan and red wavelengths that help us see the darkest and lowest contrast terrestrial surfaces that are often hazards, assess the type of and condition of vegetation, contours, and our ability to perceive wet, icy, or oily surfaces. Violets and UVA are also missing from other lamps, but these light wavelengths reveal natural fluorescence and fine textures exhibited by many fungi, insects, and plants such as nettles.  


CYRAD's technology helps you to better see difficult-to-follow hiking trails, recently trampled plants, or disturbed ground that you might have otherwise missed. CYRAD systems can even make scat and blood more visible on grass or dry ground than most blood lights.


The Light Science section of this website contains useful information about what we learned and what we have done to enhance your vision in dark places.

Loud megaphone for light and audio analogy

LIGHT ENHANCEMENT IS ANALOGOUS TO QUALITY AUDIO:  Vision and hearing both have a "midrange" of highest sensitivity often described as brightness (lumens) or loudness (decibels SPL). The Cyradiance vision-boost concept is analogous to how quality hearing aids or audio equalizers increase the sound intensity at high and/or low frequencies where your hearing is less sensitive to improve your ability to hear more detail.


You can think of red light being analogous to bass, yellow-green as midrange, and blue or violet as treble.  If you mostly put energy into the midrange of either sound or vision, many important details are lost.



Comparing light and sound frequency response
Light and Sound Have Similarities in Human Perception

You want to know the frequency range of your audio components, and you likely boost your bass and treble to hear more detail in music in frequency ranges where our hearing is weaker. You should want to do the same with your illuminating light spectra for most situations if maximizing detail perception is your goal.


Being able to illuminate using ALL color wavelengths where your eyes are most sensitive in darkness, means that you can better see the details of natural surfaces including dirt, mud, roots, bark, fungus, algae, insects, slime, scat, wetness, ice, oil films, and many types vegetation, and many rocks & minerals.


You want full-spectrum illumination to not only to make your nighttime excursions more enjoyable and also safer!

Just adding more brightness does not improve visual quality, similar to how just adding loudness does not improve audio quality.

Do you want to be more footsure at night?

DID YOU KNOW that our eyes' pupils often and unconsciously glance toward our feet when we walk or run? LEGLIGHTS add 2 additional full-color spectrum wide-angle wearable floodlights to illuminate your “Foot-forward” zone up to 30 feet. This extended peripheral view improves your footing on difficult terrain and permits better heads-up attention to your surroundings.

LEGLIGHTS provide an amazing advantage for improved footing. You may soon wonder how you got around at night without them. We designed LEGLIGHTS to be easy to use, very fast to buckle on or off,  and with very long battery life using just one AA battery per illuminator.

DID YOU KNOW that multiple angles of light are almost always present in "daylight"? Direct "sunlight" is only a part of daylight. Wide-angle "skylight" and light reflected from other surfaces at many angles play a big role in why visual details appear better in the daytime. That is why professional photography & movie studios use multiple light sources to bring out detail.


We designed our OWLSIGHT and LEGLIGHTS to work together. Multiple light angles using lamps on the head and wide-angle illuminators on both legs more closely simulate morning sunlight at your back than any single light source. This better illuminates detail and shadows, more like you get from the mix of sunlight and skylight, or like the lighting setups used in photography studios. Your perception of color hues, tints, tones, angles, depth, translucence, wetness, iciness, waxy or oily surfaces, patterns, and other visual effects are determined both by many parts of the light's color spectrum and the light angles you often unconsciously use in full-spectrum daylight.
