亮度越高的LED灯泡发热越大对散热要求越高，同瓦数下高显色(CRI90+)因光效损失反而更暗，追求高显色需选更高瓦数型号补偿约15-20%亮度损失

Unverified流明越高越亮但功率与发热同增，灯珠寿命下降；同瓦数下追求高显色指数会牺牲部分流明输出。25㎡以下客厅不必盲目堆流明，够亮且Ra90比超亮Ra80体验更好82% similarUnverified追求高亮度和高显色两者难兼顾，部分标称高亮的灯在最大功率时CRI会下降，看参数应确认是在满功率下的显色数值82% similarUnverified高显色LED为达到Ra97+通常牺牲一定光效，同功率下亮度可能不如普通LED灯泡，需要高亮度的场景可能需要选择更大功率型号80% similarUnverified调光调色功能与显色指数常存在权衡：低价调色灯通过混合冷暖灯珠实现，中间色温段（如3500K）显色指数会下降，追求高显色应选单色温高品质灯79% similarUnverified防眩光设计越好（深藏光源、格栅、磨砂罩）光效损失越大，同瓦数下深防眩灯实际亮度比裸灯低20-30%，追求氛围选防眩、追求照度需加大功率79% similar
