Full Spectrum Light Source

Full spectrum is not a technical term when applied to.

Full spectrum light source.

Grow lights are labeled with numbers like 2 500k or 6 500k which tells you the temperature of the light according to the. Key shopping considerations for grow lights cool warm and full spectrum. 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. 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.

The problem with artificial light sources is that they do not produce a full spectrum of visible light. Daylight lamps were developed based on the need to simulate daylight for health reasons in people who were denied exposure to the sun. Full spectrum light attempts to mitigate the effects of lacking natural daylight exposure. 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.

Some full spectrum light sources are also marketed as emitting ultraviolet uv radiation as well as visible light. 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. They are being replaced by new more energy efficient light sources. 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.

Manufacturers of full spectrum light sources have claimed a variety of benefits for their products including better visibility improved color rendering better health and greater productivity. Figure 1 shows the spds of two electric light sources claimed to be full spectrum the duro test vita lite 5500 fluorescent lamp and ge reveal 60w incandescent lamp as well as daylight at 5500k correlated color temperature cct. Waveform lighting s absolute series led lamps have up to 99 cri ra. Under his definition a full spectrum light source contained both visible and invisible color wavelengths of 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. The sources that produce nearly a full spectrum are being phased out for environmentalist reasons.
