Here is a semi-reliable comparison.

I just had my car rewired with a Painless Harness. Had relays put on the headlights. Running replacement GE sealed beams for now.

My friend and I bought the Hella 5.75" housings for my Roadrunner and his Charger. We put the housings on his Charger first. He had the ORIGINAL sealed beams on his car and candles would have been an improvement. We popped the Hellas on and gained a noticeable improvement. The car is now safe to drive at night.

But, the difference is in the relays. My Roadrunner with the GE (non-halogen) sealed beams is brighter even with the engine not running than his Charger with the Hellas. He not only has higher wattage bulbs and a better light pattern. The car isn't back from the wiring job yet, but when it does those Hellas are going in and I think it is going to be the end game.
