Who has a lightweight bumper beam?
I don't have one yet, but this is the one that I am going to get:

03 is the most expensive because its teh best
Ok, I have personally seen a low speed frontal collision and here's what the stock beam did:
It at least sucked up some of the impact, bent the frame rails it was attached to, and protected the radiator and a/c condenser a little.
However, the front the U-brace also gets contacted in a frontal collision and it appeared (I'm not expert) that the U-brace is a major contributor to the frontal collision and distributes the collision energy all the way down the car.
I would GUESS that the bumper beam is very useful in tying together the front frame rails... so as the beam gets crushed inwards it makes the frame rails flair inwards instead of outwards. This would seem to keep the structure "together" so that everything can crumple with the energy.
You know, we could put 1" thick steel plates around our car too and that would make it even safer.

I dont have a U brace either

Without real crash testing data it's all speculation.
However I think that the bumper beam has more to do with reducing costs in a LOW ENERGY COLLISION. That is those really low speed (under 15mph bumps) that easily bust up the radiator and light pods. I don't think it does anything significant for the engine.

~30-35mph impact @ 2.5ft diameter rock vs 1.5x0.095 in. DOM steel tube
Majority of the impact force was redirected, but I did end up slightly wrinkling the passenger frame rail and deflecting the mounting holes for the bumper beam about an inch from the original position. Other than the hemorrhaging radiator and missing bumper/light, I was able to drive away from that impact. Secondary impact (the landing from the first) also bent one of my struts but the car kept going, albeit with some negative effects to the handling.
