color and brightness. the lower the number the more "white" the light is and brighter, the higher the number the "blue"er it looks but its not as bright. If you wanna do the dual headlight mod and retain the high beam then get the H4. It will require some extra wiring and a relay, but you get both lights for low beam and high beam, and with the HID kit it wont draw too much power frying the harness. which is a common prob when doing the dual light mod, but the HID kit will eliminate that cause the bulbs fire off of ballasts instead of drawing their power straight off the battery like the halogens.
