Lighting MATTERS.

Why Lighting Matters.

Introduction

For most of human history, light came from heated sources such as fire, candles, oil lamps, and later incandescent bulbs. These sources produced a full, continuous spectrum of light, rich in red and infrared, with a natural falloff that human biology evolved under.

Modern lighting has shifted rapidly toward white LEDs, not because they are biologically familiar, but because they are efficient and inexpensive to produce. While we cannot control the lighting used in public spaces, we can control the lighting inside our homes, which is why here at Strainless, we emphasize using healthier incandescent light where it matters most.

Streetlights Then vs Now

Not long ago, streets were illuminated by halogen and sodium-vapor lights, which emitted a warm, amber-toned glow with minimal blue light. These lights were softer on the eyes and far closer to the lighting environments humans experienced for thousands of years.

Today, most cities use high-intensity white LEDs that emit strong blue wavelengths late into the night. This shift has dramatically altered the nighttime environment, making evenings brighter, colder, and more stimulating than ever before.

Car Headlights

Older vehicles relied on halogen headlights, which produced warm, diffused light with a smoother spectrum. These headlights illuminated the road without overwhelming the eyes or flooding the surrounding environment with harsh light.

Modern vehicles now use bright white LED headlights that emit intense, blue-heavy light. While they improve visibility, they also increase glare and introduce lighting conditions that are far removed from what the human visual system evolved to handle at night.

Homes and Indoor Lighting

Yes, this is the real transformation of the home from the movie, Home Alone. Look how everything has changed!

The shift toward LEDs has increasingly moved indoors, with many homes now relying exclusively on white LED bulbs. This means exposure to blue-heavy, flickering light well into the night, often in the spaces meant for rest and recovery.

This is where intentional lighting choices matter most. The home is one of the few environments we fully control, making it the ideal place to return to biologically familiar light.

Here at Strainless, we emphasize quality.

Enough is enough with LEDs. It's time to restore the warm, incandescent lighting that we used to have everywhere.
