Just wanted to share you guys the results
Greater lumens at the bulb sure, an HID bulb can push more lumens than a halogen. But there is much more involved than just the lamp itself. Optics, makes a big difference. If that light isn't focused correctly (which it isnt in a plug and play) then it is wasted.
Ill take my multiple firsthand accounts over anecdotal evidence any day. I am also an Electrical Engineer, have worked with laser optics in college and currently design commercial lighting systems and perform a lot of photometrics on HID, LED, Fluorescent and Halogen fixtures, and the optics and reflectors make a huge difference in the desired outcome.
Dont take this as disparaging to plug and play kits, I have used them and liked them fine enough. But they do not compare to OEM setups, that is all.
