    I saw the 2mm thickness listed in the video and had also wondered if that included the faces of the emitters, so thanks for clarifying. It looks like they're using the flat black chips from Osram. The rotating collars give it pause. What's up with those goofy reflectors on dual "filament" bulbs?

    Yeah, unsure, seems odd. What is also very fascinating, is the cooling air exchange is completely from within the headlight assembly, not the engine bay. This is interesting, as engine bays are hot and often dirty and wet places that are not the most suited for microprocessor cooling fans. The headlight cavity by comparison is completely sealed and clean, and this also means it will heat your headlights, which would help prevent icing in cold weather conditions. I've not seen a design like this before.

    If you get a set, a 12 hour-ish thermal tracking test would seem to be in order

    Interesting for sure and a unique solution that would seem to kill two birds with one stone. Do LED heat exchangers create enough heat to warm an entire headlight assembly enough through convection? Rather than radiant heat from infrared halogen light.

    Hard to say without testing and it would certainly depend on the size of the assembly. The back of the fan cooled Tungsram LEDs for example were 101 degrees, exhausting that into the headlight is going to offer some benefit. It certainly isn't going to have the heat output of a halogen, but it would offer improved performance vs other LEDs on the market. I don't think it will work quite as well in a projector, as the projector will get warm but there is still the cavity between the projector and the outer lens.

    The little shields help form the cutoff for lowbeam in 9003/H4/HB2/ and H19 bulbs. The lowbeam filament is offset from the highbeam filament which shifts the hotspot, and the metal shield blocks light from reaching the lower portions of the reflector that would cause glare for oncoming traffic. Highbeam filament is placed "optimally" for focus.


    Edit- Crash, do you think the design is also trying to provide additional cooling for the LED chipset due to such a thin pcb/heatsink?

    The other advantage to venting through the bulb into the headlight housing might be to help force the evaporation of any moisture that may get into the housing.

    If it's a closed loop (sealed by the bulb collar) then it won't really get rid of any moisture present. You'd still want a dry assembly before installing.

    Agreed, but remember, most housings have a vent.

    Ah, I was not aware. There's a truck parked on my block that has the blacked out headlights and they're always sweaty on the inside. Maybe just poorly sealed.

    That thought on the cooling configuration definitely crossed my mind.

    Just yesterday, as I lazed on the couch contemplating life, I daydreamed "wouldn't it be cool if LED bulbs had the fan inside of the headlight assembly".

    Maybe if I become lazier and dream harder, my next thoughts will become reality too!

    I've had many of these thoughts for vehicles that later become a reality, somehow I need to monetize that better.

    Most bikes I've owned or worked on have zero room behind the headlight for anything. Even attempting to put a cooling fan back there would be pointless because there's no air flow.

    i just replaced my oem halogens with the tungsram +130s. is it necessary to readjust my headlights because of the increased output? seems like they’re shining much higher than oem

    Theoretically, you should not have to. Many cheap aftermarket replacement bulbs do require re-aiming due to poor process control as to where the filament is located. You should not have that problem with those particular bulbs.

    I stuck the Hikari ultras in my low and high beams. Low beams are better than silverstars, high beams I’ll probably go back to the h9 bulb.

    I disagree...installed the Nova today, different light output from oem 2021 halogens to alpharex led
