Full Spectrum Light Source

Key shopping considerations for grow lights cool warm and full spectrum.

Full spectrum light source.

Some full spectrum light sources are also marketed as emitting ultraviolet uv radiation as well as visible light. The sources that produce nearly a full spectrum are being phased out for environmentalist reasons. Artificial light sources will inevitably fall short of 100 replicating natural daylight but the degree to which a full spectrum light source comes close to natural daylight plays a significant role in determining its effectiveness. Full spectrum light attempts to mitigate the effects of lacking natural daylight exposure.

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. Under his definition a full spectrum light source contained both visible and invisible color wavelengths of light. That includes servicemen on navy submarines and astronauts in the space program. Many growers take advantage of led lights to help scale plant production due to their full light spectrum capabilities low heat waste and maintenance and extended lifespan.

In particular sunlight is considered full spectrum even though the solar spectral distribution reaching earth changes with time of day latitude and atmospheric conditions. Grow lights are labeled with numbers like 2 500k or 6 500k which tells you the temperature of the light according to the. Truly full spectrum light sources by virtue of being similar to natural daylight must have a very high cri and color temperature between 4000k and 6500k to be considered a true full spectrum light source. Daylight lamps were developed based on the need to simulate daylight for health reasons in people who were denied exposure to the sun.

Light sources promoted as full spectrum can cost over ten times as much as nearly identical products that do not bear the full spectrum claim. The problem with artificial light sources is that they do not produce a full spectrum of visible light. Used as either a sole light source indoor or supplementary greenhouses leds help plants grow using full spectrum lighting at a lower cost than traditional hps lamps 1. Light source the problem energy efficient lights have poor spectral response.

Waveform lighting s absolute series led lamps have up to 99 cri ra. They are being replaced by new more energy efficient light sources.
