When we pay our electricity bill, we are paying for the watts we use. Since we have traditionally used incandescent light bulbs, we are accustomed to using watts as a unit of brightness, but this is incorrect. The measure of the brightness of a light fixture is lumens, not watts.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"size-full wp-image-20033 aligncenter\" src=\"https:\/\/luxmanlight.com\/wp-content\/uploads\/2024\/03\/images.png\" alt=\"lumen and watt\" width=\"275\" height=\"183\" srcset=\"https:\/\/luxmanlight.com\/wp-content\/uploads\/2024\/03\/images.png 275w, https:\/\/luxmanlight.com\/wp-content\/uploads\/2024\/03\/images-18x12.png 18w\" sizes=\"(max-width: 275px) 100vw, 275px\" \/><\/p>\n<h3 style=\"text-align: left;\"><span class=\"ez-toc-section\" id=\"Understanding_Lumens\"><\/span>Understanding Lumens<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: left;\">Lumens are the measurement of visible light energy. The higher the number of lumens, the brighter the light.

Due to variations in specifications among manufacturers and market supply-demand issues, there are still many LEDs on the market ranging from 130 lm\/W to 190 lm\/W. Therefore, when selecting the brightness of a light fixture, it is essential to pay attention to lumens.<\/p>\n<p style=\"text-align: left;\">Incandescent technology typically produces 12-18 lumens per watt, while halogen technology usually produces 10-20 lumens per watt.<br \/>\nTherefore, for the same wattage, the brightness of LED bulbs is approximately 10-14 times that of incandescent bulbs and about 10 times that of halogen bulbs. You can roughly refer to this indicator when choosing light fixtures.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"lumens_to_watts_conversion_chart_in_led_light_Luminous_efficacy_130_lmW\"><\/span>lumens to watts conversion chart (in led light Luminous efficacy 130 lm\/W)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<table class=\"alignleft\">\n<tbody>\n<tr>\n<td width=\"160\">Lumens<\/td>\n<td width=\"160\">Incandescent Watts<\/td>\n<td width=\"160\">Halogen Watts<\/td>\n<td width=\"160\">LED Watts<\/td>\n<\/tr>\n<tr>\n<td width=\"160\">100<\/td>\n<td width=\"160\">7<\/td>\n<td width=\"160\">6<\/td>\n<td width=\"160\">0.77<\/td>\n<\/tr>\n<tr>\n<td width=\"160\">375<\/td>\n<td width=\"160\">25<\/td>\n<td width=\"160\">20<\/td>\n<td width=\"160\">2.9<\/td>\n<\/tr>\n<tr>\n<td width=\"160\">450<\/td>\n<td width=\"160\">30<\/td>\n<td width=\"160\">25<\/td>\n<td width=\"160\">3.5<\/td>\n<\/tr>\n<tr>\n<td width=\"160\">800<\/td>\n<td width=\"160\">60<\/td>\n<td width=\"160\">45<\/td>\n<td width=\"160\">6<\/td>\n<\/tr>\n<tr>\n<td width=\"160\">1100<\/td>\n<td width=\"160\">75<\/td>\n<td width=\"160\">60<\/td>\n<td width=\"160\">8.5<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<div class=\"mceTemp\" style=\"text-align: left;\"><\/div>\n<h2><\/h2>\n<h2><\/h2>\n<h2><\/h2>\n<h2><\/h2>\n<h2><\/h2>\n<h2><span class=\"ez-toc-section\" id=\"Lumen_to_watt_chat_In_different_led_Luminous_efficacy\"><\/span>Lumen to watt chat (In different led Luminous efficacy)<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<table width=\"452\">\n<tbody>\n<tr>\n<td width=\"123\">Lumens to watt<\/td>\n<td colspan=\"4\" width=\"329\">Luminous efficacy(lm\/W)<\/td>\n<\/tr>\n<tr>\n<td>Lumens<\/td>\n<td>130 lm\/W<\/td>\n<td>150 lm\/W<\/td>\n<td>180 lm\/W<\/td>\n<td>200 lm\/W<\/td>\n<\/tr>\n<tr>\n<td>100 lm<\/td>\n<td>0.8w<\/td>\n<td>0.7w<\/td>\n<td>0.6w<\/td>\n<td>0.5w<\/td>\n<\/tr>\n<tr>\n<td>500\u00a0 lm<\/td>\n<td>4w<\/td>\n<td>3w<\/td>\n<td>3w<\/td>\n<td>3w<\/td>\n<\/tr>\n<tr>\n<td>1000\u00a0 lm<\/td>\n<td>8w<\/td>\n<td>7w<\/td>\n<td>6w<\/td>\n<td>5w<\/td>\n<\/tr>\n<tr>\n<td>2000\u00a0 lm<\/td>\n<td>15w<\/td>\n<td>13w<\/td>\n<td>11w<\/td>\n<td>10w<\/td>\n<\/tr>\n<tr>\n<td>3000\u00a0 lm<\/td>\n<td>23w<\/td>\n<td>20w<\/td>\n<td>17w<\/td>\n<td>15w<\/td>\n<\/tr>\n<tr>\n<td>4000 lm<\/td>\n<td>31w<\/td>\n<td>27w<\/td>\n<td>22w<\/td>\n<td>20w<\/td>\n<\/tr>\n<tr>\n<td>6000 lm<\/td>\n<td>46w<\/td>\n<td>40w<\/td>\n<td>33w<\/td>\n<td>30w<\/td>\n<\/tr>\n<tr>\n<td>8000 lm<\/td>\n<td>62w<\/td>\n<td>53w<\/td>\n<td>44w<\/td>\n<td>40w<\/td>\n<\/tr>\n<tr>\n<td>10000 lm<\/td>\n<td>77w<\/td>\n<td>67w<\/td>\n<td>56w<\/td>\n<td>50w<\/td>\n<\/tr>\n<tr>\n<td>15000 lm<\/td>\n<td>115w<\/td>\n<td>100w<\/td>\n<td>83w<\/td>\n<td>75w<\/td>\n<\/tr>\n<tr>\n<td>20000 lm<\/td>\n<td>154w<\/td>\n<td>133w<\/td>\n<td>111w<\/td>\n<td>100w<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 style=\"text-align: left;\"><span class=\"ez-toc-section\" id=\"How_to_verify_the_reliability_of_Luminous_Efficacy\"><\/span>How to verify the reliability of Luminous Efficacy<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p style=\"text-align: left;\">Rely on the manufacturer\u2019s provided Luminous Efficacy Test Report.<\/p>\n<h2 style=\"text-align: left;\"><span class=\"ez-toc-section\" id=\"How_do_I_know_how_many_lumens_I_need\"><\/span>How do I know how many lumens I need?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3 style=\"text-align: left;\"><span class=\"ez-toc-section\" id=\"Lumen_calculator\"><\/span>Lumen calculator<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: left;\">You can use a lumen calculator to determine this, at <a href=\"https:\/\/www.omnicalculator.com\/everyday-life\/lighting\" target=\"_blank\" rel=\"noopener\">https:\/\/www.omnicalculator.com\/everyday-life\/lighting<\/a><\/p>\n<h3 style=\"text-align: left;\"><span class=\"ez-toc-section\" id=\"How_many_lumens_are_needed_for_outdoor_street_lights\"><\/span>How many lumens are needed for <a href=\"https:\/\/luxmanlight.com\/ms\/\">outdoor street lights<\/a>?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p style=\"text-align: left;\">The number of lumens required for street lights depends on several factors, such as the height of the light pole, the width of the road, and the amount of ambient light available.
