Can I get away with 100W H4 bulbs?

Hi, one of the headlights in the Agila has gone, and the H4 bulbs I have in now are like candles.

Anyone know of any good ones so I can upgrade?

I've seen some 100W ones that I like the sound of, was just wondering if I could get away with them as they're better than HIDs which have the wrong beam pattern and things
I literally just want the brightest, thanks ☺
