Light Wattage - Blue halogens?

:
Mazda 323 Protege SP20
Hi,
I want to upgrade my high beam lights. Don't want to spend money on a proper HID Xenon kit.
The stock bulbs I have at the moment are 55W H1 high beams and I want to upgrade these to some of those blue tinted halogen lights (anyone know if these have better light?).
What is the max wattage I can go for before I risk melting the headlight?

Cheers
