When it comes to LED lighting, this type of spectrum is often referred to as full-spectrum LED, which is in contrast to the more conventional narrow-spectrum LED alternative. It is especially crucial to provide well-balanced lighting conditions to plants grown under sole-source LED lighting.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:1,&quot;335551620&quot;:1,&quot;335559738&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p style=\"text-align: left;\"><span data-contrast=\"none\">LED grow lights with a spectrum optimized for plant growth may not excel in PPE due to the PPE variations among LED elements in different colors.

PAR consists of the blue, green and red spectral range (400-700 nm). Generally, a grow fixture with a high content of red light has high PPE due to the high efficiency of red LEDs. It is, therefore, not uncommon for fixtures with the highest PPE to have a spectrum with high red content (90-95%) and some blue content (5-10%).<\/span><span data-ccp-props=\"{&quot;134233117&quot;:false,&quot;201341983&quot;:0,&quot;335551550&quot;:1,&quot;335551620&quot;:1,&quot;335559738&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">\u00a0<\/span><\/p>\n<p style=\"text-align: left;\"><span data-contrast=\"none\">However, far-red (FR) light (700-800 nm), which lies outside of PAR and is thus not included in PPE calculations, has a positive effect on plant development, architecture, and flowering as shown in numerous research papers.
