Lumens measure total light output, but lux tells you how much light actually reaches your subject. Always compare <strong>\u9023\u7d9a\u30e9\u30a4\u30c8<\/strong>\u200b by their lux rating at 1 meter.<\/p><p class=\"wp-block-paragraph\"><strong>How many lumens do I need for a continuous light studio setup?<\/strong><\/p><p class=\"wp-block-paragraph\">There&#8217;s no single answer because lumens don&#8217;t measure what reaches your subject. A more useful number: aim for a <strong>\u9023\u7d9a\u7167\u660e<\/strong>\u200b fixture that delivers at least 20,000 lux at 1 meter for a small studio, and 50,000+ lux at 1m for larger setups.<\/p><p class=\"wp-block-paragraph\"><strong>What is a good lux level for portraits with continuous light?<\/strong><\/p><p class=\"wp-block-paragraph\">For portraits, around <strong>5,000 to 20,000 lux on the subject&#8217;s face<\/strong>\u200b is a comfortable range. You&#8217;ll be working at distances of 1\u20132 meters, so a 200W\u2013300W <strong>continuous LED<\/strong>\u200b at 1m spec of 30,000+ lux gives you plenty of headroom to dim down for soft, natural-looking light.<\/p><p class=\"wp-block-paragraph\"><strong>How does distance affect my continuous light output?<\/strong><\/p><p class=\"wp-block-paragraph\">Lux from your <strong>\u9023\u7d9a\u7167\u660e<\/strong>\u200b drops with the <strong>square of the distance<\/strong>. Double the distance, you get one quarter of the lux. Triple the distance, you get one ninth. This is why high-lux <strong>\u9023\u7d9a\u7167\u660e<\/strong>\u200b fixtures at 1m are essential when you need to light subjects at 3+ meters.<\/p><p class=\"wp-block-paragraph\"><strong>Can I convert lumens to lux for a continuous light?<\/strong><\/p><p class=\"wp-block-paragraph\">Not directly, because lux depends on the beam angle and distance. A 5,000-lumen <strong>\u9023\u7d9a\u7167\u660e<\/strong>\u200b in a tight 30\u00b0 beam can deliver a very high lux at the center, while the same 5,000 lumens in a 120\u00b0 flood will give a much lower lux reading. Always request the manufacturer&#8217;s lux-at-distance spec for fair comparison.<\/p><p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>If you&#8217;re shopping for a continuous light\u200b and have ever stared at two LED spec sheets trying to figure out which one is actually brighter, you&#8217;ve probably noticed that one says lumensand the other says lux. They&#8217;re not the same number, and they&#8217;re definitely not interchangeable. Picking the wrong measurement for your photography could mean spending $500 on a light that looks bright on paper but falls short at the distance you actually shoot. Let me clear this up.
