Ordered the bulb from Rakuten JP. The total charge from credit card is $130.92

Due to the depreciation of Japanese Yen, it's a good timing to buy things from Japan.
(Does Lexus lower their price? ha..)
Just received the package from Japan today.

BTW, 6200K is much cheaper than 6000k.
(6000K D4S is about USD119; 6200K D4S is about USD 81)

Comparing to the original bulb, I think the difference is very limited.
I should buy 6200K or 6700K.
