What is natural spectrum light.

In particular sunlight is considered full spectrum even though the solar spectral distribution reaching earth changes with time of day latitude and atmospheric conditions. Full spectrum and natural spectrum describe light that is close to natural daylight. Almost all plants and animals need regular exposure to full or natural spectrum light to maintain biochemical balance and optimal health. Sunlight in its pure form has a kelvin temperature of around 5 000 degrees kelvin and a color rendering index of 100.

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. Specifically it should have a cri color rendering index of 95 or better and a color temperature of 6500k. A light whose spectrum closely mimics that of natural daylight. For the purposes of this discussion as well as our internal quality control and specifications at waveform lighting we define full spectrum light as.

Very simply put a lighting source that closely replicates natural sunlight can be considered a natural light source. Unlike ordinary indoor lighting full spectrum light includes all colors in the electromagnetic wavelength from infrared to ultra violet visible and non visible note that all verilux light therapy lamps are manufactured to be uv free. Natural spectrum generally means the bulb produces light at the same frequencies as natural sunlight. 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.
