Thanks Dan for your time and effort.

I did for get to mention that both H4 conversion bulbs are made out of glass.

Hella lenses are curved.

Koito lenses are flat.

Just adding a comment from my experience - I've not had good results with those LED H-series replacement lamps.  The few I've tried did not work properly with the reflector and lens used for the filament lamps.  The ones I tried required a fairly large adjustment to get the light where it was supposed to be.  Once that was done, they had a good cutoff but there was no significant difference between the high beam light pattern and the low beam light pattern.  I believe that's because the LED emitter locations and configuration are not the same as those for the filaments in the incandescent bulbs, so the light output pattern is not consistent with that of the filament bulbs.

I have installed the Toyota Kit H4’s, and need to adjust the beams (as I should have done with the OEM bulbs), H4’s are brighter.
As I had previously installed relays and a circuit breaker for the headlights, I didn’t use any of the wiring that came with the Toyota kit.
The $16 for the kit and $10 for shipping is worth it, IMO.
