The future of HID headlights.
Everyone is saying LED tech is the future of automotive lighting in headlights and foglights. I beg to differ.

at claimed 140 lumens per watt, I'd much rather invest in this than the LED technology. However they did not address how much heat it does give off. considering how big of a housing they used to demo.
They did not show how large of a ballast is needed to power the unit either.
At 100 lumens per watt the current HID is quite bright and compact, it is actually quite hard to match its efficiency with size. Considering the newest fad of the LED headlights on the LS600 or the new escalade platinum, neither one generate as much light as a HID bulb per headlight, but they each need enormous housings to cool the high power LEDs they shoved in it.
Until they come up with some real replacements, HIDs are here to stay.

i looked into their technology. The solid state unit requires significant cooling which current headlight enclosures can not accommodate. It will take significant redesign for them to account for limited space and heat generation issue.
Two things they will have to over come before this goes automotive; the "on time" is 10 to 20 seconds (acording to the website). Much too long for an automotive application. Second. a 250 watt bulb at 13.8 volts will draw over 18 amps EACH!
^ they will need to redesign it for smaller voltage and size. Im sure they won't only have 1 type of bulb. It is this solid state technology that they have developed that is going to make a difference in the long run.
