Hi Folks, I finally got a round tuit and measured the relative light output (low beam) of the 3 cars (to compare to the LED Leaf replacements):
Of course it depends on distance, so just measured each at a foot away for peak light output with a solar power meter TM-206 Tenmars (measures W/M2) Google shows X 63.5 for lumens (not sure how the 3000 lumens Fed limit distance measurement/concentration pattern is) ; Bolt 2020 = 251 W/M2 x 63.5 = 15.9K lumens Tesla-Y 2021 = 202 W/M2 x 63.5 = 12.8K lumens Leaf 2013 (new Leds) = 248 W/M2 x 63.5 = 15.7K lumens So the Leaf with the new Leds (below) are about the same as the Bolt and within 19% of the Tesla (which may be spread out pattern a bit more). The marketing claim of 26K lumens (doesn't indicate distance) is of course BS as noted by Amazon reviewers but brightness level is on par with other current production vehicles. I think Dave asked about the dispersion pattern, it appears to be somewhat more spread out at distance (compared to the Tesla projector bulbs) but similar in pattern to the Bolt. Cars seem to vary quite a bit on dispersion pattern and I'm nightly blinded by newer cars with tiny piercing headlights (with big fake plastic grills), not sure how some manufacturers get away with not following federal guidelines. Time will tell how reliable the Leds are, let you know in 10 years...

Shows 26000 Lumens 6500K color rendition (blue-white), $50 for two LED bulbs. It looks like on Amazon they also sell 40K lumen even brighter for $64 in H13 hi/lo beam style. With regards to lumens: The great god google: "3000 lumen is the national limit. 6500k means it's that blue-white light color. Most of the LED bulbs on Amazon MASSIVELY overstate their true numbers, but some of them are legitimately that bright (and illegal to use on the road)." https://www.amazon.com/dp/B0DG8ZW3FJ?ref=ppx_yo2ov_dt_b_fed_asin_title The Chinese product lumen rating appears to be inflated. They're brighter than the existing headlights, about what the Chevy Bolt is but would have to get a lumen meter for an accurate number - but they're a huge improvement. Not sure about reliability, time will tell, got 4.3 stars on Amazon Have a renewable energy day, Mark Mark E.

They sell 24,000 33,000 and 44,000...some of which I worry may be illegally bright...
