Good light quality is achieved through a balance of wavelengths selected to create an ideal environment, specifically for plants.

A test was conducted where two different spectra compositions were evaluated and compared to each other. The power consumption was the same and all other conditions were kept exactly the same for both test subject groups. One had a spectrum that had a high fixture PPE (HE) and the other was designed to have a high growth efficacy (GE) but a lower fixture PPE (LE). The fixture with the spectrum designed to promote plant growth had a better result across the board, with an average between 12 &#8211; 28% higher biomass production.<\/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}\">&nbsp;<\/span><\/p>\n\t<div class=\"img has-hover x md-x lg-x y md-y lg-y\" id=\"image_1715679558\">\n\t\t\t\t\t\t\t\t<div class=\"img-inner dark\" >\n\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"531\" height=\"228\" src=\"https:\/\/heliospectra.com\/wp-content\/uploads\/2023\/11\/article-expanding-the-term-plant-lighting-efficacy-3.jpg\" class=\"attachment-large size-large\" alt=\"Lemon balm results from trial\" srcset=\"https:\/\/heliospectra.com\/wp-content\/uploads\/2023\/11\/article-expanding-the-term-plant-lighting-efficacy-3.jpg 531w, https:\/\/heliospectra.com\/wp-content\/uploads\/2023\/11\/article-expanding-the-term-plant-lighting-efficacy-3-300x129.jpg 300w\" sizes=\"auto, (max-width: 531px) 100vw, 531px\" \/>\t\t\t\t\t\t\n\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\n<style>\n#image_1715679558 {\n  width: 68%;\n}\n<\/style>\n\t<\/div>\n\t\n\n\t<div id=\"text-1520225258\" class=\"text\">\n\t\t\n\n<p><em><span class=\"TextRun SCXW189962438 BCX8\" lang=\"SV-SE\" xml:lang=\"SV-SE\" data-contrast=\"none\"><span class=\"NormalTextRun SpellingErrorV2Themed SCXW189962438 BCX8\">Growth<\/span> <span class=\"NormalTextRun SpellingErrorV2Themed SCXW189962438 BCX8\">Efficacy<\/span><span class=\"NormalTextRun SCXW189962438 BCX8\"> test <\/span><span class=\"NormalTextRun SpellingErrorV2Themed SCXW189962438 BCX8\">results<\/span><span class=\"NormalTextRun SCXW189962438 BCX8\"> by <\/span><span class=\"NormalTextRun SpellingErrorV2Themed SCXW189962438 BCX8\">Heliospectra<\/span><span class=\"NormalTextRun SCXW189962438 BCX8\"> en <\/span><span class=\"NormalTextRun SpellingErrorV2Themed SCXW189962438 BCX8\">its<\/span><span class=\"NormalTextRun SCXW189962438 BCX8\"> partners<\/span><\/span><span class=\"EOP SCXW189962438 BCX8\" data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335551550&quot;:1,&quot;335551620&quot;:1,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\">&nbsp;<\/span><\/em><\/p>\n\t\t\n<style>\n#text-1520225258 {\n  font-size: 0.9rem;\n}\n<\/style>\n\t<\/div>\n\t\n<p style=\"text-align: left;\"><span data-contrast=\"none\">Heliospectra offers one of the market\u2019s most sophisticated products which stimulates growth characteristics and improves plant quality.
