What Is Natural Spectrum Light

Almost all plants and animals need regular exposure to full or natural spectrum light to maintain biochemical balance and optimal health.

What is natural spectrum light.

The term natural lighting is one that is thrown around quite loosely these days in the lighting industry. Full spectrum light is light that covers the electromagnetic spectrum from infrared to near ultraviolet or all wavelengths that are useful to plant or animal life. Very simply put a lighting source that closely replicates natural sunlight can be considered a natural light source. A light whose spectrum closely mimics that of natural daylight.

Specifically it should have a cri color rendering index of 95 or better and a color temperature of 6500k. Since there s no pr. Full spectrum and natural spectrum are often used interchangeably and are both terms describing bulbs and lamps that mimic natural daylight. Full spectrum and natural spectrum describe light that is close to natural daylight.

Natural spectrum generally means the bulb produces light at the same frequencies as natural sunlight. In particular sunlight is considered full spectrum even though the solar spectral distribution reaching earth changes with time of day latitude and atmospheric conditions. It mimics sunlight to provide a clear white light that up until relatively recently was the only light humans knew for hundreds of thousands of years. But sunlight is also a full spectrum with some peaks and valleys as well including a moderate valley on the blue end due to the spectrum of the sun and atmospheric absorption.
