Maybe cause I had HID's in my car before changing over to Projector LED's.
I changed over from 4"x6" Hella E code H4's with 35 watt HID electronic ballasts and anti glare shield for my lows and Hella E code H1's with 100 watt bulbs prior to my switch. This set up needed a custom wiring harness featuring double relays and double fused vs projector LED's which are plug n play and draw less current than the antiquated stock factory halogen headlights that came with these cars. The LED's offer a much broader light pattern with a more defined cut off and are not likely to blind oncoming traffic. I have some pictures to post for any non-believers.
Don't want to get into a pissing contest here, but I've had personal "behind the wheel" experience with both of these in 4"x6" format & can tell you there is no comparison between the two. That's a fact
The fact is you didn't have the bi xenon hi/lo HID nor did you have the HID for your hi beam. The Hella lens I have have a cut line and there is no need for an anti glare shield.
