Why green light over red light? DEX FINGERLIGHT’s Light Mode Explained

We designed the DEX FingerLight^¹ to deliver convenient and wearable light faster and more conveniently than standard headlamps and flashlights.  With three versatile light modes and seven additional features packed into a 1” high-tech wearable gadget, we prioritized functionality for anyone needing brightness, but also dim and stealth light to minimize intrusion and preserve night vision.  This includes uses for camping, hunting, aviation, and even nurses caring for patients in darkness.

As a father and sons founding team, we had many "design debates" backed by science and market research for green light mode instead of a red light mode.  Why green?  Primarily, green light has measurable advantages over red for the human eye with a minimal difference (if any) for stealth and preservation of night vision.

The Science

Improved Visibility

Green light is much better for the human eye to distinguish objects and colors in the dark.  Mathematically, green is 25% to 50% better than red in nanometer wavelengths.  This is especially crucial for hunters scanning trails, campers navigating campsites, and pilots reading instruments during night flights.  Green light strikes the perfect balance of brightness—helping you see clearly without being harsh on your eyes or those around you. 

Night Vision

While red light is often praised for preserving night vision, green light actually provides more night vision benefit. For hunters at dusk or campers exploring trails or dark tents and RVs, green light allows you to maintain close up depth perception and better vision for distance.  Even for general household use, green light offers a more subtle yet visible amount of light to perform tasks that would be exceedingly difficult in red light due to loss of depth perception.

Enhanced Usability for Pilots and Patient Care

For healthcare professionals and pilots, green light is gentler than white light while offering more illumination than red. It’s bright enough to perform precise tasks with minimum disturbance or loss of night vision.  When we surveyed pilots, the outcome was 50-50 green v. red.  Several published studies clearly indicate that overnight hospital inpatients who get better sleep recover more quickly after surgery, have lower comorbidities, higher satisfaction, and are discharged sooner.  We think sleep disturbance in overnight patients is widely overlooked nuance that has severe consequences for recovery and healing.  The published literature proves it.  It is time to bring awareness to sleep quality in hospitals and a contributing factor to healing.

Non-Intrusive for Wildlife

While red is a common light for hunters, green light is arguably just as effective.  Deer and other mammals see movement more than color.   What makes DEX FingerLight even more effective is its wearable versatility.  Hunters wear it under their fingers on the palm side to hide and deflect the beam toward the ground, treestand step, a weapon, or a decoy.  DEX can be quickly turned on and off with the same hand where it is being worn. This versatility makes DEX a one-of-a-kind tool for hunters, anglers, and campers observing nocturnal animals. The softer, natural hue of green is less alarming to animals, giving you the edge when you need to stay undetected. 

Furthermore, and to our surprise during our research, twice as many hunters preferred green light over red light.  In fact, twice as many preferred a dim white light over a red light.

As mentioned, we were actually surprised by these findings, but the reasons provided confirmed the science we discovered: they said green light provides better visibility than red light does.

Universal Utility Across Professions

When my sons and I chose which color light to implement into the DEX FINGERLIGHT design, we “debated” the options, rationales, and conducted market research about which color would appeal overall to our target audience.  We chose green because of the aforementioned rationale based upon bona fide research and customer opinions. 

From tradesmen to pilots to hunters to delivery drivers to simply reading a book, green light is versatile.  It provides the perfect amount of brightness for working in confined spaces, reading labels, or navigating unfamiliar paths, making it an all-around better option than red.
