Get it wrong here and you\u2019ll pay the price in terms of electricity, yield and quality throughout the entire season.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this guide, we get straight to the point: what types of LEDs are available, how to work out the wattage you need, what to expect in terms of energy consumption and performance, and what the most common mistakes growers make when choosing their lighting are.

First-generation LEDs were a rip-off: they promised the same results with half the power consumption but produced small, airy buds with little resin.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That has changed. Today\u2019s full-spectrum LEDs \u2014 particularly those using Samsung LM301B\/LM301H diodes or equivalent high-quality components \u2014 produce buds that rival the best HPS results, whilst generating less heat and consuming between 30\u201350 % less power.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The change is not just technological. It is economic: with the rise in electricity prices in Spain, the monthly saving from using a good LED light rather than a 600W HPS can exceed \u20ac20\u201330 per cycle, depending on the tariff. You can recoup the price difference in two or three harvests.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\"><\/th><th class=\"has-text-align-left\" data-align=\"left\">Full-spectrum LED<\/th><th class=\"has-text-align-left\" data-align=\"left\">HPS 600W<\/th><th class=\"has-text-align-left\" data-align=\"left\">CMH \/ LEC<\/th><\/tr><\/thead><tbody><tr><td><strong>Actual consumption<\/strong><\/td><td>240\u2013480W<\/td><td>660W (with ballast)<\/td><td>315\u2013630W<\/td><\/tr><tr><td><strong>Heat generated<\/strong><\/td><td>Low\u2013moderate<\/td><td>Very high<\/td><td>Moderate<\/td><\/tr><tr><td><strong>Service life<\/strong><\/td><td>50,000\u2013100,000 hours<\/td><td>10,000\u201320,000 hours<\/td><td>20,000h<\/td><\/tr><tr><td><strong>Spectrum<\/strong><\/td><td>Full spectrum \/ adjustable<\/td><td>Orange \/ red<\/td><td>Large, similar to the Sun<\/td><\/tr><tr><td><strong>Starting price<\/strong><\/td><td>High<\/td><td>Lower-middle<\/td><td>Medium<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"tipos-led\">Types of LEDs: not all are the same<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The market for grow lights is a minefield. There are models costing \u20ac50 and others costing \u20ac800, and the difference isn\u2019t always obvious from the technical specifications. Here are the main categories:<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Panel-type LED (the most common)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A rectangular board with tens or hundreds of diodes arranged across a flat surface. It is the most common type and the one with the widest range of quality. What distinguishes a good panel from a mediocre one:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>The diodes it uses:<\/strong> The Samsung LM301B and LM301H are the benchmark in 2026. Epistar and generic Chinese LEDs work, but with lower luminous efficiency (less PPFD per watt).<\/li>\n\n\n\n<li><strong>The driver:<\/strong> The component that converts the current. Meanwell is the most reliable manufacturer. A cheap driver is the most common point of failure in budget LEDs.<\/li>\n\n\n\n<li><strong>Heat dissipation:<\/strong> Thick aluminium heat sinks and generously sized panels are a sign that the manufacturer hasn\u2019t cut corners here.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Bar-type LED (elongated quantum board)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Long, slender bars arranged throughout the space, usually suspended in parallel. They are highly efficient at distributing light across the canopy as they eliminate the central hotspot. Ideal for spaces measuring 1.2 \u00d7 1.2 m or larger.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">COB (Chip-on-Board) LEDs<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A single high-power chip concentrated in one spot. They produce a very intense, penetrating light that reaches deep into the canopy. They are more difficult to position correctly (they require just the right distance) but, in experienced hands, they deliver excellent results. Less popular than panels due to their complexity.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">\u00abBlurple\u00bb (purple) LEDs: avoid them<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The purple panels from the previous generation combined basic red and blue LEDs. They were cheap and did the job, but their efficiency is far lower than that of today\u2019s full-spectrum panels. If you see a cheap LED with intense purple light, it\u2019s technology from 8\u201310 years ago. Give it a miss.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"calcular-potencia\">How to work out the power you need<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The figure that really matters isn\u2019t the panel\u2019s wattage: it\u2019s the <strong>PPFD<\/strong> (Photosynthetic Photon Flux Density), which measures the photons useful for photosynthesis that arrive per square metre per second (\u00b5mol\/m\u00b2\/s). It is the true measure of light intensity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, as most growers do not have a PPFD meter, the rule of thumb based on actual wattage remains a useful starting point:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">Growing area<\/th><th class=\"has-text-align-left\" data-align=\"left\">Recommended actual LED power<\/th><th class=\"has-text-align-left\" data-align=\"left\">Target PPFD (flowering)<\/th><\/tr><\/thead><tbody><tr><td>0.6 \u00d7 0.6 m (small cupboard)<\/td><td>100\u2013150W (actual)<\/td><td>600\u2013800 \u00b5mol\/m\u00b2\/s<\/td><\/tr><tr><td>0.8 \u00d7 0.8 m<\/td><td>200\u2013250W actual<\/td><td>700\u2013900 \u00b5mol\/m\u00b2\/s<\/td><\/tr><tr><td>1.0 \u00d7 1.0 m<\/td><td>300\u2013350W (actual)<\/td><td>800\u20131000 \u00b5mol\/m\u00b2\/s<\/td><\/tr><tr><td>1.2 \u00d7 1.2 m (standard)<\/td><td>400\u2013480W actual<\/td><td>900\u20131100 \u00b5mol\/m\u00b2\/s<\/td><\/tr><tr><td>1.5 \u00d7 1.5 m or more<\/td><td>600\u2013700W actual (or 2 panels)<\/td><td>1000\u20131200 \u00b5mol\/m\u00b2\/s<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Important:<\/strong> The wattage stated by the manufacturer is usually the theoretical peak, not the actual power consumption from the mains socket. A panel advertised as \u00ab600W\u00bb may actually consume 280\u2013320W. Always look for the actual power consumption figure or \u00abtrue power\u00bb.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For vegetation, you can use 60\u201370 % of the flowering intensity. Many modern panels are fitted with dimmers that allow you to adjust the power according to the growth stage.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"espectro\">The spectrum: what it means and what the plant needs<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cannabis primarily utilises two ranges of the light spectrum:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Blue (400\u2013500 nm):<\/strong> Essential during the vegetative phase. It promotes compact growth, broad leaves and thick stems. A plant that receives too much red and too little blue during the vegetative phase will \u00abstretch\u00bb excessively.<\/li>\n\n\n\n<li><strong>Red (620\u2013700 nm):<\/strong> The driving force behind photosynthesis during flowering. Plants on a 12\/12 cycle need plenty of red light to develop dense buds.<\/li>\n\n\n\n<li><strong>Far-red (700\u2013780 nm):<\/strong> The latest-generation LEDs include far-red light because it triggers the Emerson effect: it increases photosynthetic efficiency when combined with standard red light. Its most interesting application is the <strong>EOD (End-of-Day) pulse<\/strong>: add 15\u201330 minutes of far-red light at the end of the light cycle to signal \u00absunset\u00bb to the plant and induce flowering more quickly. An Australian study published in <em>Scientific Reports<\/em> They tried reducing the photoperiod from 12 hours to 10 hours plus 2 hours of far-red light and recorded a 70% increase in THC yield in the Northern Lights variety, with an additional energy saving of 5.5%. <a href=\"https:\/\/thecannex.com\/es\/luz-roja-lejana-cannabis-crecimiento-final-dia\/\" target=\"_blank\" rel=\"noreferrer noopener\">Find out more about the \u2018far-red\u2019 effect at the end of the day \u2192<\/a><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">A good full-spectrum LED covers all these ranges in the right proportions for both phases. You don\u2019t need to buy a different LED for the vegetative and flowering stages.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">LEDs with an adjustable spectrum (separate channels for the vegetative and flowering stages) are useful if you want to optimise your setup as much as possible, but for most growers, a fixed full-spectrum setup is sufficient and much easier to use.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"distancia-altura\">Distance and altitude: the most costly mistake<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Hanging the LED too close will burn the plants. Hanging it too far away wastes light intensity and results in airy, weak buds. The correct distance depends on the panel\u2019s power output and the stage of the grow cycle.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">General distance guide for full-spectrum LEDs using Samsung diodes:<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th class=\"has-text-align-left\" data-align=\"left\">Actual panel power<\/th><th class=\"has-text-align-left\" data-align=\"left\">Spacing during germination \/ seedling stage<\/th><th class=\"has-text-align-left\" data-align=\"left\">Distance through vegetation<\/th><th class=\"has-text-align-left\" data-align=\"left\">Distance during flowering<\/th><\/tr><\/thead><tbody><tr><td>100\u2013150W<\/td><td>40\u201350 cm<\/td><td>25\u201335 cm<\/td><td>20\u201330 cm<\/td><\/tr><tr><td>200\u2013300W<\/td><td>50\u201360 cm<\/td><td>35\u201345 cm<\/td><td>30\u201340 cm<\/td><\/tr><tr><td>400\u2013480W<\/td><td>60\u201380 cm<\/td><td>45\u201360 cm<\/td><td>35\u201350 cm<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How to recognise a light burn:<\/strong> The leaves closest to the light source turn yellow or whitish at the edges (bleaching), without the typical symptoms of a nutrient deficiency. If you notice this, raise the panel by 5\u201310 cm and reassess after 48 hours.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The hand test:<\/strong> Hold the back of your hand at the level of the highest buds for 30 seconds. If you feel an uncomfortable heat, the LED is too close. With modern, low-heat LEDs, this test is less relevant, but it is still useful as a quick guide.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"consumo-rendimiento\">Actual consumption vs expected performance<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Let\u2019s look at the figures that really matter when planning your setup.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A full grow cycle in a 1.2 \u00d7 1.2 m grow tent with a 480W LED (actual power):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Vegetation (4 weeks at 18 hours per day):<\/strong> 480W \u00d7 18 hours \u00d7 28 days = 241.9 kWh<\/li>\n\n\n\n<li><strong>Flowering (8 weeks at 12 hours per day):<\/strong> 480W \u00d7 12 hours \u00d7 56 days = 322.6 kWh<\/li>\n\n\n\n<li><strong>Total cycle:<\/strong> ~565 kWh \u00b7 Based on the average Spanish electricity tariff of 0.18 \u20ac\/kWh \u2192 <strong>~\u20ac102 on electricity per harvest<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The same setup with a 600W HPS (660W actual with ballast):<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Total cycle:<\/strong> ~776 kWh \u2192 <strong>~\u20ac140 on electricity per harvest<\/strong><\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The difference is around \u20ac38 per harvest. If you produce three harvests a year, the annual saving exceeds \u20ac110. In 3\u20134 years, the higher initial cost of the LED is fully recouped, and you\u2019ll continue to use the same panel for another 10+ years.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"errores\">The 5 most common mistakes when choosing LED lighting<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Relying on the advertised wattage<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The market is full of panels advertised as \u00ab1000W equivalent\u00bb that actually draw 100W. Always check the actual power consumption at the mains socket, not the theoretical wattage or the HPS equivalent.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Buy the cheapest LED available<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A \u20ac40 LED from AliExpress might work, but its diodes are of poor quality, the driver will fail within 12\u201318 months and the spectrum won\u2019t be optimised. The total cost (including poor harvests and replacement) ends up being higher than buying a good-quality one from the start.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Not taking residual heat into account<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Modern LEDs generate much less heat than HPS lamps, but they are not heat-neutral. A 480W panel raises the temperature inside the grow tent by 4\u20138 \u00b0C. If your grow tent is already in a warm room (25\u201328 \u00b0C in summer), you\u2019ll need a more powerful extraction system than you might have thought.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Ignoring the uniformity of the PPFD<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A panel with high intensity in the centre but poor coverage at the edges produces very uneven buds. Ask the manufacturer for the PPFD map at the intended usage distance, or look for it in independent reviews before buying.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Not adjusting the distance according to the phase<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many growers hang the LED at a fixed height and leave it untouched throughout the entire cycle. During the vegetative stage, you can afford to keep it further away so as not to force growth. During flowering, moving it closer to the safe limit makes a real difference to the density and potency of the buds.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"variedades\">00 Seeds strains that perform best under LED lighting<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Not all strains perform in the same way under LED lighting. Pure Indica and Indica-dominant strains \u2013 which are the hallmark of 00 Seeds \u2013 respond particularly well: their compact structure makes better use of the uniform light distribution, and their metabolism adapts easily to modern full-spectrum lighting.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">For indoor LED lighting, our selection:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"https:\/\/00seeds.com\/en\/2026\/02\/24\/gorilla-glue-strain-cannabis-cultivation-00-seeds\/\">Gorilla Glue<\/a><\/strong> \u2014 One of the best strains for maximising resin production under LED lighting. Its 65\u201370-day flowering period makes the most of modern full-spectrum lighting.
