What are the specs of the New Astro City fluorescent lamp? (Color temp, lumens, etc)

(crossposted on arcade projects for a larger sample size)

My NAC came with a Toshiba FL15D, which is a 6500K 700 lumen bulb. This is such a high color temp that it makes the marquee look kind of washed out. Is this the original lamp? What lamp (model number) was in your NAC if yours came straight from a Japanese arcade? I'm trying to figure out the specs of the original NAC lamp, if that's even possible.

FL15D or FL15N.
D (4200 °K) and N (6500 °K) corresponding to the "heat" of the color. "N" style is less blue-ish.

I think you have it backwards, the D is 6500K. Did they just ship with both at different times?
