In an airplane, I suspect the bluish-white bulbs produce about half the lighting as a standard white H3 bulb. Much of this is subjective. In order to obtain the STC, tests were run to determine illumination, visibility and other effectiveness issues. If either type of light is properly aimed, center of beam illumination will be good, so there is no major advantage to the Eclipse H3 here. I found that overall illumination to be superior with the Eclipse H3 because of the light pattern and the fact that it is easier to see objects which are not in the center of the beam.
Tower controllers seem to like it, so it makes a good identification light.
The light seems superior for taxi use because of its reduced glare. These two features gives the Eclipse light better utility. In the airspace around Boeing Field, it is common to see opposite direction traffic. I found it advantageous to leave the light on while in such airspace. For H3-100, current is 8 amps.
