Audi had a neat Supeebowl commeecial touting a new LED headlight. Does anyone know what emitter it might be and what the ouput could be?
Any guess as to who will go LED next?

The emitter is a blue laser (like on a blu-RAY player) and a remote phosphor. The output is probably 1000 lumens per lamp ballpark, and there aren't too many advantages yet.Audi had a neat Supeebowl commeecial touting a new LED headlight.

I've done a bit of work with video. On a set, especially to capture motion, you want bright lights. Rock shows use short-arc lamps of incredible brightness (several at a time) to do video of the guy on stage. I suspect that watching the video set in person, the Audi headlights were not that impressive compared to the light output of the lighting for camera work. Bring a 12V battery and a stock car headlight into an office-level brightness (300 lux) and fire it up - it won't look so impressive....They had to use perhaps a foursevens stopsign light or some other similar source...

Turns out headlamps are 750 lumens apiece, when wired properly. I think that you ought to check your headlamps for proper function. Reflectors and covers are the biggest culprit, but if your car eats headlamps then you might be rattling them to death.With the Audi lamps, or properly designed LED headlamps? I'll take 750lumens of 5000k Cree for driving over a stupid halogen bulb anyday. Sick of changing bulbs in my car given it's usually a cop that tells me they are burnt out anyways.
Ouch, man. Ouch.
