What are the disadvantages of full spectrum LED grow lights?
A major problem with many full spectrum LED grow lights is that they are designed to give the appearance of daylight without being custom-tailored for rigorous plant growth. It’s the reason why we at LumiGrow coined the phrase, “PAR is for plants and Lumens are for humans.” Not all wavelengths of light are optimal for photosynthesis.
What are the health benefits of full spectrum lighting?
The health benefits of full spectrum lighting are not directly related to the way we see light or color. Instead, it relates to other biological processes, such as the way pigments and hormones such as melanopsin in the human body react to various wavelengths and intensities of light.

What is the effect of full spectrum light?
First, full-spectrum light sources typically have a high correlated color temperature (CCT) of 5000K - 7500K. Lamps with higher CCT values produce greater brightness perception than lamps with lower CCT of the same luminance. Second, most full-spectrum light sources have high color rendering properties, meaning that surface colors will appear more saturated. Greater saturation will also give the impression of greater brightness (Boyce, 1977). Third, the ultraviolet (UV) radiation produced by some full-spectrum fluorescent lamps has a fluorescing, brightening effect on textiles and paper that have been treated with whitening agents. These combined effects on brightness perception may indeed have positive impact on building occupants, but greater perceived brightness can also be a liability, depending upon the expectations of the space's occupants (Veitch and McColl, 2001).

Full-spectrum light sources and visual performance. Full-spectrum light sources will not provide better visual performance than other light sources under most circumstances. Visual performance is the speed and accuracy of processing achromatic information (e.g., black print on white paper) by the human visual system.
Is full spectrum light good for you?
Full-spectrum light sources and psychological benefits. Full-spectrum light sources may have psychological benefits, particularly in societies that place value on "natural" environments. One of the claims often associated with full-spectrum light sources is that they are most like natural daylight. Unlike full-spectrum electric light sources, however, daylight does not have a fixed spectrum. Rather, natural light varies with latitude, time of day, season, cloud cover, air pollution, ground reflectance, and, if a person is indoors, window tinting. Nevertheless, it cannot be denied that people consistently prefer natural lighting from windows and skylights to electrical lights. These preferences are robust and may reflect psychological associations with the natural environment that produce positive affect in many people. Positive affect induced by daylight may, in fact, help improve mood and motivation and thus increase productivity and retail sales. Full-spectrum light sources offer this positive association with daylight. Although positive psychological benefits from full-spectrum light sources may have been observed in some circumstances, there appears to be no biophysical explanation for those observations (Heschong, Wright & Okura, 2000). Still, the power of psychological associations cannot be denied and it is certainly conceivable that cleverly marketed full-spectrum light sources may provide beneficial effects to some people susceptible to that marketing. As NLPIP's survey demonstrated, there appears to be a strong positive association with full-spectrum light sources that has resulted from marketing, presumably because of the association between full-spectrum lighting and "natural" light.
What is a full spectrum light?
A full spectrum light covers light from infrared to a near-ultraviolet on the electromagnetic spectrum. These lights contain all the wavelengths which are useful to human beings, animals and even plant life.

What is a broad spectrum lamp?
Broad-spectrum lamps include all fluorescent lamps with a whitish or white appearance. The broad-spectrum lamps do emit any UV rays. These lamps have a color temperature of 3000-4000 Kelvins and are easier on the eyes than full spectrum lamps. Doctors who are treating patients with macular degeneration often recommend the broad-spectrum lamp as they offer less blue exposure.
How many nanometers are in a full spectrum lamp?
A full spectrum lamp operates from 400 to 800 nanometers. This color-corrected light will imitate or simulate the brilliance of sunlight at noontime. This light can be measured by Kelvin Temperature (Degrees Kelvin), or by the Color Rendering Index(CRI). The secret to achieving optically balanced light to full-spectrum is how close the optics come to natural sunlight.
