Has anyone tried replacing the stock H7 headlamps with Silver star Ultras?

Dave

 

I have an 2004 car and need to replace the headlight bulb. I bought Sylvania H7 bulb for it. These bulbs are so dim. I need more light to drive with. Has anyone used any of the Sylvania Silver stars (3 different ones)?/ I am looking at the Philips X-Treme Power and GE Nighthawk Platinim. The bulbs cost a bit to replace. Does anyone have any advice????
Thank you
