PIAA 510 or 540

[Grape Ape]

I'm trying to decide between the 510 and 540's. Does anyone have any suggestions or experience with either or both? Also, white vs. Ion Fog input would be appreciated.

I recently installed a set of 540 Plasma Ion fogs and they are up near the top of my favorite mods list. The size is great mounted on my Bull Bar. After much research I went with the fogs over driving lights and that was a great decision for me. I run them all the time whereas I would hardly ever have the occasion to use driving lights.
