Has anyone tried this lighting combo?

[12 Volt Man]

one Hagen Powerglo 18,000K standard flourescent

and

one All-glass 8000K standard flourescent?

I like the look of both bulbs individually (AG is a bright pinkish hue, Powerglo is a bright white with a hint of blue)

I was thinking of trying one of each in a dual 36" fixture..

thanks
