The name says it all

PIAA's Intense White bulbs produce a more radiant whte beam without any hint of blue. This bulb has been completely re-engineered from the ground up. What you will see in the 9005 and 9006 bulbs is a larger than-standard glass tube that increases output (28% whiter color than Star White) and allows the bulb to burn at much cooler temperatures. PIAA's new Intense White Bulbs provide the best possible balance between performance and bulb life.
