Hello - I am biased as I own Diode Dynamics. That said, I wanted to point out one more extremely serious flaw in the test methodology. None of the measured data is accurate or relevant for any comparison purposes. They used a fan to generate airflow, and did not allow the lamps to stabilize. This is completely contrary to any and all standard LED lighting test procedures, and it's also not clear whether there was any consistency in the level of airflow.
From the ELS whitepaper: "The standard LM-79-19 stabilization procedure was not followed and instead the product was energized for 5 minutes before photometric measurements were taken. A fan was used on all test samples throughout testing to ensure sufficient airflow to prevent thermal management systems from engaging."
I think my favorite part in all of this is "4 seconds is enough time to react". Why wouldn't I want all the time I can get to react to that critter whose just trying to cross the road? I'll take all the seconds I can get:-) My biggest challenge is low beams. I drive unlit, slower speed (45ish) roads where vast majority of the time I can only use the lows, and my lows are awwwfulll.
Oh, and low beams: make sure you're swapping out your bulbs once a year or so, they grow dimmer over time. Assuming you have reflector housings, running a higher quality bulb can make a noticeable difference. Obviously don't try to put LEDs in a reflector housing.
Thanks! I just swapped new halogens last month. Next step is to find a shop with a headlight aimer and make sure I'm aligned properly. Then I'll have a baseline to determine future steps if need be.
There should be no need whatsoever to pay someone to do that. Headlights are designed to be user adjustable using simple tools only. Just look at your owner's manual, or put your year/make/model in YouTube. It blows my mind that more drivers don't understand that. Connor's wife (referenced in story) has been complaining about how bad her low beams are. When I borrowed that truck, they were pointed up at like 30 degrees.
Yeah, I think that's just indicative of being completely racing focussed, with little idea of what an actual consumer wants or needs. Driving behind the HTX2s is just so freakin' relaxing.

Paul, you should send me an email.
