As Im a poor french it is very hard to explane you why but if you install them in paralel you will loose a lot of light in the glass of the tank

Aniway I will try to explane Look carfuly the bulb. It is a cylinder so it spread the light all over it on the other hand the top dont spead a lot and the soket block most of the light so if you put the bulb in paralel you will have in your tank the light of the tip and the socket but most of the light that the cylinder spread will be directed in the glass

Hope you will understand
