Headlight Max Wattage

I'm planning on getting raybrig bulbs for my 99 civic. Two questions:

1. Does anyone have any opinion or advice on this brand? Do they last
long?

2. Does anyone know what's the maximum or safe range for the
wattage so I don't melt the wires? There are two types of bulbs (both
raybrig) I am looking at. One has a 110/100w output, and the other
is 120/115w. Which one would be better (or safer)?? (The company's
link is pasted below)

The Hyper Halogen series has an output of 110/100w for H4 and the Racing Hyper Halogen Magnum White has an output of 120/115

raybrig bulbs are cool, kind of expensive though. About the wattage, it really depends on your luck. I had 110/90 watt bulbs in my car, and they were fine, I know civic owners who used the same wattage, and it melted thier harnesses.

I personally prefer PIAA Hyper Whites
and if you actually want to spend it.....install a hid conversion
