H4
Low: 910 lumen, 50 watt
High: 1500 lumen, 60 watt
H7
Low: 1350 lumen, 55 watt
High: N/A
1350 lumen is a lot more than 910 lumen.
If you want to be technical, the Camaro's stock 9006 low bean bulb is brighter than the H4's low beam filament.
9006
Low: 1000 lumen, 55 watt
High: N/A
You can get a "hyper" H7 which is basically a H9 capsule on a H7 base.
H9 is also a low-beam-only bulb.
H9
Low: 2000 lumen, 65 watt

These specs are from Sylvania's regular Halogen.
Now comparing to HID..... HID is typically 3200+ lumen (depending on OEM wattage and bulbs versus some higher output aftermarket).

I can't say for certain which of these two housings is better because I haven't seen the beam patterns of both housings for comparison. There were a couple threads a while back in which InfiniteReality said that he didn't like the beam pattern of the eurolamps housings. I didn't see any beam pattern pics comparing both housings though. Maybe he has some pics somewhere he can post. The pic I saw had HID installed in the eurolamps housings and the beam pattern was indeed bad, but then again it was HID in a Halogen reflector. He switched to some Bosche housings (I think they are the ones in this thread), but I couldn't find beam pattern pics. He said that he liked the Bosche ones better, but he put HID into them which is comparing apples to oranges when talking about H4 vs H7.
You could always use upgraded wiring with a relay to install higher wattage H4 bulbs in the housings. Just make sure to use upgraded wiring and that the bulbs really are the higher wattage and not fake (most are).
