H4 is H4 and its dual filament type e.g. hi-lo beam.
i was happy with the ebay LED but never got to test them at dark'o'clock but people i ride with said they were bright. BTW the LED ones like normal bulbs are all to do with Watts e.g. 50w and some are better than others.
the best hedlights i have ever had on my bike were hids4u 50w 5000k hid, they were super bright with a decent beam pattern and pure crisp white light not chavvy blue 6000k
the SV headlight loom is also known to be a problem.
