You should watch the Youtube videos from a company called Headlight Revolution. They test a bunch of LED 7" and replacement H4 LED bulbs in the standard lens. Probably the best info on LED lighting you'll find. They show you in real beam patterns that not all LEDs are created equal. I have Wipac Quadoptic 7" with Morimoto 2Stroke 2.0 LED bulbs in them, they have a really nice bright beam and a distinct cutoff so you don't blind oncoming drivers, not cheap but to my eyes worth it. I only wish I had found Headlight Revolution before I bought the Morimotos, they had better results with GTR Ultra 2, one advantage of the Morimoto LED is they have very low current draw. Headlight Revolution also has a great video on aiming the lights which also improved the usable light from my set up.
