The brighter the light source, the more lumens it produces. The measurement of lumens is weighted and adjusted based on <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/en.wikipedia.org\/wiki\/Luminous_efficiency_function\">how humans perceive light<\/a>.<\/p>\n<p>So, for example, if you compare one light bulb that outputs 900 lumens and one that outputs 2000 lumens, the 2000 lumen bulb will be brighter than the 900-lumen bulb. The more lumens a light bulb emits, the brighter the bulb.<\/p>\n<figure style=\"width: 650px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-769823 size-full\" data-pagespeed-lazy-src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2021\/11\/bulb_efficiency_graph.jpg?trim=1,1&amp;bg-color=000&amp;pad=1,1\" alt=\"A light efficiency chart by bulb type.\" width=\"650\" height=\"485\" data-crediturl=\"https:\/\/www.shutterstock.com\/image-vector\/light-bulb-efficiency-comparison-chart-infographic-188741972\" data-credittext=\"Alhovik\/Shutterstock.com\" src=\"\/pagespeed_static\/1.JiBnMqyl6S.gif\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><figcaption class=\"wp-caption-text\">Different bulb types produce more lumens while using fewer watts. <span class=\"imagecredit\"><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/www.shutterstock.com\/image-vector\/light-bulb-efficiency-comparison-chart-infographic-188741972\">Alhovik\/Shutterstock.com<\/a><\/span><\/figcaption><\/figure>\n<p>This means a good measurement for light bulb efficiency is <a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/en.wikipedia.org\/wiki\/Luminous_efficacy\">lumens per watt<\/a> (lm\/W).
