CCD/CMOS sensors are more sensitive at longer wave lengths (towards the red end of the spectrum). So on my D70, for instance, an Osram deep red LED looks brighter than it's normal red counter part, however a human's eye says that the normal red LED is brighter! Also before anyone can make that call from those photos people need you to take a photo of the lights which aren't fully saturated (your first picture). Then we need the following information:
The nominal LED wave length
The LED spectrum spread
The IR cut off filter wavelength
The CCD/CMOS sensor in the camera
The red quell balancing algorithm of the camera
Only then does anyone have a chance of really answering your question. It would also be nice to have the luminosity plot of the lenses used on those lights. A tight centre beam may be hiding a higher luminosity at extreme angles - throwing 30% of your lumen out in the +/-80 to 135 deg band will significantly reduce the centre spot brightness compared to a lens which has 0 illumination beyond +/-90 degrees.
