Projector headlights

ok i tried to get better lighting so i changed the bulb on my kouki s14 and the bulb iden. was right because its supposed to be H1 but when i changed it i noticed that the PIAA bulbs werent as white as my foglights(non projector) that are H3 but the thing is the colour is supposed to be the same because they say the same colour on the box , im thinking that the headlights arent as bright because they are projector so mabey the lense is causing the discolouration, am i right?

Could be different wattage, or lense.
Sometimed different types of bulbs just dont match.

hmm im thinking it is the lense because i followed the bulb type in thr manual and its also stated on the headlight it self
