When I was in my room, the bathroom light where the shower is, which has a flush mount fixture and has CFLs in it. One cool white and other being daylight, put the two together kinda makes a clear MV lamp color. Is this true, yes or no?

I could see that happening. The color temperature of clear MV is around 5700-6000K so a cool white (4100K) and daylight (6500K) CFL would make a 5300K color, roughly equal to a clear MV, but a little warmer. Two daylight CFLs might be a closer match, but the CRI would be way too good. two 4100K CFLs would make a very close match for /DX MV though. A large wattage 4100K CFL would look nice in a cobrahead without a ballast. A 65W 4100K CFL would closely match the output of a 100W MV lamp.
