Thanks for sharing.

Did you take the halogen photos first, and the LED photos later? There is more light from the sky in the halogen photos and less with the LED indicating that either the halogen photos were shot when there was more light out, or the exposure/aperture/sensitivity settings on the camera were different.

I find before/after photos to be inadequate to show relative brightness unless they can be taken with manually controlled settings that hold everything equal. But as you say, it shows the beam pattern which is valuable.
