從H502D -> H502C
流明大概是打85折
等SC62D出來後，看一下數據再決定要不要等c好了

yes, difference between 4000K & 5000K hi-cri versions is minimal, 4-5%

small quota from datasheet : (it's raw LED lumens, not OTF. In real life you will get slightly less lumens, because we loss few % of light on reflector and glass)

Part Number CCT CRI, minimum Typical Luminous Flux (lm)
_ _ _ 350 mA 1000 mA

LXH8-FW40-Y 4000K 80 min _ 114 288 lm
LXH8-FW50-Y 5000K 80 min _ 120 300 lm

Cree XM-L2 : (1000 mA , calculated Minimum Luminous Flux (lm))

Neutral White 3700 K -- 5000 K 357 lm (T5 group)
Neutral White 3700 K -- 5000 K 330 lm (T4 group)
