Lumens measure how much light comes out, so compare lumens rather than watts. Most integrated LED fan lights in our range put out around 1,700 to 2,000 lumens, for example 2,011 lumens on the 52" Noosa and 1,800 on the 52" Skyfan. As a rough guide, allow about 100 to 150 lumens per square metre for a bedroom and 150 to 250 for living areas and kitchens. A 3 by 3 metre bedroom needs roughly 1,000 to 1,500 lumens, so a typical fan light covers it comfortably. A 5 by 5 metre living room needs roughly 3,500 to 6,000 lumens, so plan extra lighting there. The lumens for each fan are listed on the product page.
