Phew, where to start?
OK, the numbers on HIDs, like 4300K, are called "colour TEMPERATURE", and the higher the number, the LESS usable light the "bulb" puts out, since the higher temperatures produce more blue than white and the human eye can't use it.
So-called "Xenon" bulbs aren't really, the are halogen bulbs with a little Xenon gas in the envelope to try for that much desired blue-ish tint.
Higher wattage bulbs are not e-marked, therefore not suitable for road use.
Higher wattage bulbs have been known to cause wiring and bulb connectors to overheat with disastrous results.
The maximum wattage allowed for a forward-facing bulb in the EC is 60W. Most headlight bulbs are 60, 60/55, or 55W.
You CAN fit so-called "uprated" bulbs, which draw the usual 60W but give the light output of, say, 90W, these would be 50% uprated.
They now exist up to 100% uprated, and should be E-marked.
These bulbs, and higher wattage tend to have shorter lives.
ALWAYS buy branded bulbs. Cheap copies only need to have their filaments misaligned by 0.25mm to produce LESS usable light than a standard bulb
PIAA bulbs are over-hyped, over-advertised, and over-rated. They are also over-priced!
The best uprated bulbs at present are made by Osram, Philips and GE who do them for Halfords.
HIDs in an aftermarket kit are now illegal, since the bulb and reflector/lens are incompatible.

Have had PIAAs and they are great plus last a lot longer than the Philips I had before. However, they are very expensive so when one finally went last month, I replaced them with Ring Xenon UltraMax 120%... for £20 a pair of H4s, I don't think you can do much better... Light output is as good if not better than the PIAAs too.
