Many of the Coralife 50/50 lights come with the blue/white

All 50/50 lights are 50% actinic(blue) and 50% white. Hence the name.

They are not as practical as a two bulbs: one actinic, and one
white. The actinic tubes don't last as long as the white so you end up
changeing the 50/50 when the white side is still good.

Ah, I see. When I purchased it, my LFS thought that some came with two white
tubes instead but they did tell me that the blue would wear out first. I'll
probably switch to a double white after six months. I do like the way it
makes my fish and plants look though.
