Unverified85% confidenceDecision RuleTime unknown
全光谱灯泡的流明效率普遍低于普通LED（约70-90lm/W vs 100-130lm/W），替换普通灯泡时需按流明选而非按瓦数，否则会明显偏暗

Unverified全光谱灯泡实测光效通常仅60-80lm/W，明显低于普通LED的100-150lm/W，因此同等亮度下功率更高、发热更大，需为吊灯预留散热空间并注意驱动电源寿命89% similarUnverified全光谱灯泡光效普遍偏低，同等瓦数亮度约为普通LED的70-80%，需按'实测流明'而非瓦数选购，替代60W白炽灯需约800lm、Ra95全光谱通常需10-13W88% 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%88% similarUnverifiedLED灯泡的实际光效应关注流明/瓦比值，优质产品应达到90-120lm/W，低于80lm/W说明能效偏低或散热设计差88% similarUnverified全光谱高显色灯泡因需牺牲部分发光效率，同等亮度下功率比普通LED高约20-40%，选购时看流明（lm）而非仅看瓦数，Ra97的10W灯泡实际亮度可能只相当于普通7W87% similar
