Update with pictures on the headlight bulbs. Finally got off my butt and measured the wattage of these.
As I said before, I'm pretty happy with how little light scatter there is, and with the clean cutoff, despite being LEDs in housings made for halogens.
On Amazon they're advertised as "80w - 9600 lumen" (40w per bulb). The 9600 lumen claim was clearly bunk, but turns out so was the 40w per bulb claim. With my meter I measured 2.63 amps low beams and 3.93 amps high beams, which works out to around 18w low / 27w high per bulb, using 13.8v as a reference. If wattage scaled linearly, to hit their advertised 40w, these bulbs would need ~20.4v.
They're really not bad. Low beams are 1/3 the wattage of halogens with similar usable light output, but if I had to buy again I'd look around to see if I could find something a bit brighter. The images above exaggerate their light output a bit compared with what my eyes see.
