xtreme power bulbs: 80% more light output.
NO blue coating on the bulbs.
I don't care what anyone says. if you have two bulbs of the same wattage and size and one has a blue coating on it and the other doesn't, the one without the blue coating will have better light output.
also, xtreme power bulbs have a wider beam spread. (more euro style) you WILL have to lower your beam.
