elementor-clearfix\">\n\t\t\t\t<p><span lang=\"EN-US\">In this blog, I&#8217;ll bust some myths about PAR readings and cast a light on a very important range of the light spectrum, that\u2019s still \u201cin the dark\u201d!<\/span><\/p><p><span lang=\"EN-US\">In lighting blog #2, I explained about <u><a href=\"https:\/\/g1.redseafish.com\/?p=55652\">Reef-Safe and REEF-SPEC lighting<\/a><\/u>.<\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">Today, I&#8217;m going to shed some light on PAR measurements. We all use PAR meters to measure light in our reef aquariums. But, is it possible that it&#8217;s obscuring part of our view?<\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">The PAR measurement was developed for the terrestrial photobiology research of plants and crops. It represents the intensity of Photosynthetic Active Radiation within the visible light spectrum spanning between 400 to 700 nm (nanometers).<\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">But the spectrum that is relevant for the corals starts below the range of the visible light in the UV region and continues into the blue part of the visible light range.<\/span><\/p><p><span lang=\"EN-US\">This section of the spectrum is between 360 to 480 nanometers and is the Photosynthetic Utilized Radiation or PUR that is actually used by the corals.<\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">So, you can already see that using PAR measurements to determine the suitability of light for corals doesn\u2019t tell us the whole story. On the one hand, the PAR measurement is missing an important part at the bottom end of the spectrum (360-400 nm). These wavelengths, in the UV range, below 400 nanometers, enhance coral growth and color expression and stimulate the auto-recovery process of photosynthesis.<\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">And on the other hand, at the top end of the spectrum, any wavelength above 480 nanometers, meaning a significant part of the PAR measurement, that includes the green, yellow, and red wavelengths, cannot be utilized by corals.<\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">In excessive amounts, these wavelengths may turn into heat energy inside the soft tissue of corals, which causes stress and photoinhibition. I\u2019ll explain more about that in our <u><a href=\"https:\/\/g1.redseafish.com\/?p=55669\">next blog<\/a><\/u>.<\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">You\u2019re right if you think that the zooxanthellae can use the red end of the light spectrum, but they\u2019re fine without it. And since these algae sit inside the coral\u2019s soft tissue, the red light may damage the coral before it can be utilized by the zooxanthellae. Bottom line,our research shows we\u2019re better off without it.<\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">To sum it up, PAR tells us about the intensity of the full visible light spectrum, but it doesn\u2019t tell us anything about the suitability of the light source for a reef aquarium.<\/span><\/p><p><span lang=\"EN-US\">PUR, on the other hand, tells us exactly what we need to know.\u00a0<\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">Unfortunately, there are no coral PUR meters. To precisely measure PUR underwater, you need to use a special device like the Ocean Optics Radio Spectrophotometer we use during our research. It provides us the specific spectral irradiance for each individual wavelength which allows us to calculate the percentage of PUR from the regular PAR reading.<\/span><\/p><p><span lang=\"EN-US\">Based on our research, we recommend checking out the percentage of PUR from the PAR reading when evaluating or comparing lights for a reef aquarium. <\/span><\/p><p><span lang=\"EN-US\">\u00a0<\/span><\/p><p><span lang=\"EN-US\">In my next blog, I\u2019ll dive deep into <u><a href=\"https:\/\/g1.redseafish.com\/?p=55669\">light versus dark period and the relationship between spectrum, intensity, and photoperiod <\/a><\/u>&gt;&gt;<\/span><\/p><p>Check out our <a href=\"https:\/\/g1.redseafish.com\/hardware\/reefled\/\" target=\"_blank\" rel=\"noopener\">ReefLEDs<\/a>, the Reef-Safe lighting that deliver the precise light spectrum, intensity, and photoperiod that provide the optimal conditions for corals to flourish.<\/p>\t\t\t\t\t<\/div>\n\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-2bcbd6ce elementor-widget-divider--view-line elementor-widget elementor-widget-divider\" data-id=\"2bcbd6ce\" data-element_type=\"widget\" data-widget_type=\"divider.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-divider\">\n\t\t\t<span class=\"elementor-divider-separator\">\n\t\t\t\t\t\t<\/span>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-638bfa9b elementor-widget elementor-widget-heading\" data-id=\"638bfa9b\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">More to explore<\/h4>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-1799a8ec elementor-posts--align-left elementor-grid-3 elementor-grid-tablet-2 elementor-grid-mobile-1 elementor-posts--thumbnail-top elementor-card-shadow-yes elementor-posts__hover-gradient elementor-invisible elementor-widget elementor-widget-posts\" data-id=\"1799a8ec\" data-element_type=\"widget\" data-settings=\"{&quot;cards_row_gap&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:16,&quot;sizes&quot;:[]},&quot;_animation&quot;:&quot;fadeIn&quot;,&quot;cards_columns&quot;:&quot;3&quot;,&quot;cards_columns_tablet&quot;:&quot;2&quot;,&quot;cards_columns_mobile&quot;:&quot;1&quot;,&quot;cards_row_gap_tablet&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]},&quot;cards_row_gap_mobile&quot;:{&quot;unit&quot;:&quot;px&quot;,&quot;size&quot;:&quot;&quot;,&quot;sizes&quot;:[]}}\" data-widget_type=\"posts.cards\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-posts-container elementor-posts elementor-posts--skin-cards elementor-grid\">\n\t\t\t\t<article class=\"elementor-post elementor-grid-item post-55669 post type-post status-publish format-standard has-post-thumbnail hentry category-reef-lighting\">\n\t\t\t<div class=\"elementor-post__card\">\n\t\t\t\t<a class=\"elementor-post__thumbnail__link\" href=\"https:\/\/g1.redseafish.com\/light-intensity-photoperiod-relationship\/\" ><div class=\"elementor-post__thumbnail\"><img width=\"1024\" height=\"575\" src=\"https:\/\/g1.redseafish.com\/wp-content\/uploads\/2020\/01\/light6-1024x575.png\" class=\"attachment-large size-large\" alt=\"\" loading=\"lazy\" srcset=\"https:\/\/g1.redseafish.com\/wp-content\/uploads\/2020\/01\/light6-1024x575.png 1024w, https:\/\/g1.redseafish.com\/wp-content\/uploads\/2020\/01\/light6-300x168.png 300w, https:\/\/g1.redseafish.com\/wp-content\/uploads\/2020\/01\/light6-768x431.png 768w, https:\/\/g1.redseafish.com\/wp-content\/uploads\/2020\/01\/light6-e1582529352412.png 1000w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/div><\/a>\n\t\t\t\t<div class=\"elementor-post__badge\">Reef lighting<\/div>\n\t\t\t\t<div class=\"elementor-post__text\">\n\t\t\t\t<h3 class=\"elementor-post__title\">\n\t\t\t<a href=\"https:\/\/g1.redseafish.com\/light-intensity-photoperiod-relationship\/\" >\n\t\t\t\tLight intensity &#038;
