DIFFERENT housing, comparing halogen to LED.
This is a cheap projector from amazon,

I picked it up along with the LED (link above) to tinker a bit with. All in all, it's probably all going back for a refund, but here's the skinny before it goes.
1st pic is the halogen H3 included with the lamp. It has some sort of cutoff, and a bit of leakage going upwards on each side. It's got a pretty pronounced lower ring on the ground, which won't do anything good for distance vision. Still, as an augmentation to low beams, I've had vehicles which would have been helped by these, as you can see that the hotspot is still forward in the beam, centered reasonably below the cutoff on the garage door.
2nd pic is with the 9006 LED. The lamp accepts either. You can see how it loses control of the light. There's a ton of leakage off both sides, and less intensity in the distance where you want it. The glare on the sides really hurts its use in traffic. I wouldn't want someone else driving towards me with them.
3rd pick is with the lower part of the lens masked, a little on the bottom center working up to about a 3rd of it towards the outside R-L. That really knocks down the glare and restores the cutoff, but the distribution ends up with a lot of light in the nearfield where it hurts distance vision, and not a great amount left on the road ahead.
Keep in mind - the H3 has a lateral filament while the 9006 is axial, so that alone should cause inconsistency between swapping these two sources. The crispness of the LED makes me think this is intended for a 9006 originally.
NOT TRIED - and perhaps I need to... is a halogen 9006. The glare shield on the front of a 9006 might provide that crisp cutoff and avoid the glare off to the sides. Maybe. It's a stretch.
I believe that some tweaks to the internal glare shield could really make this thing pretty good - similar has been done with other projector models. These seem glued pretty effectively, however, and I'm weighing that $30 cost to experimentation as to whether I attempt to go there or just send them back.
So - out of the box I wouldn't use it, except maybe with the H3. With an LED drop-in, I definitely would not use it without modification. With mods, it could certainly provide better light than a lot of other products in its class.
