I'm currently using the Philips Lumileds that i've posted earlier on this thread (yes, us ebay link cause i'm from Portugal and posting was cheaper).
I'll try to get some photos of LED lamps in action so you can get an idea.
One thing for sure, they are really pure white (no blue halo) and much brighter than halogen.
The light's cover field is the same as halogen but more vivid, everything is lightened up.
And is instant on and zero headlight heating of the glass.
I didn't have HID but I would say HID could light more distance (the good HIDs ones).
The LED lamps are plug and play. Don't have to drill or glue or put ballasts out (modern ones don't even have exterior ballast anymore as they're built in). Mine have tiny digital ballasts but they are small and fit inside the headlight itself. I've purchased new ones with all built in to high beams.
The best thing is that can nivelate them as you usually do with halogen using the headlight bolts.
I ride everyday with them and no other driver complains. I've made a road test with my friend's car riding in front and behind him and didn't glare him at any time.
I'm very pleased with these lamps and i'm using them from 2015!!
