Unverified亮度看流明(lm)不看瓦数：LED约100-120lm/W，替换传统60W白炽灯选约800lm的LED（约8-9W），40W白炽灯约450lm对应5W LED88% similarUnverified光效指标看流明每瓦(lm/W)而非单看功率：优质LED灯泡≥90lm/W，9W可达800流明以上，替代传统60W白炽灯；只标功率不标流明的产品需警惕虚标86% similarUnverifiedLED灯泡实际亮度看流明(lm)而非瓦数，替换60W白炽灯需约800lm(约8-10W LED)，替换100W需约1600lm(约14-16W LED)，光效达标的LED应≥100lm/W86% similarUnverified看流明而非瓦数选灯，LED光效差异大：劣质灯80lm/W，优质灯120lm/W以上，同样30W实际亮度可差50%86% similarUnverified客厅吸顶灯按面积选流明：15㎡以下选2000-3000lm，15-25㎡选3000-4000lm，25㎡以上需4000lm以上或多灯组合。LED流明比换算约为100lm/W，切勿只看瓦数86% similar
