Question for everyone that has the LUX LED AEs
OK, I have those AEs...I know they are recalled...and I know what they said on the recall...but can someone please explain this to me:
U really think the temperature in the engine bay is cooler than the inside of the headlight housing. Go feel how hot the engine bay is after just running your car for a while (maybe just 3 miles), I will be really worried about the LUX LED power pack overheating by leaving it outside the headlight housing if the issue is really temperature related. So from what I see, by leaving it outside the headlight housing just prevent the failure from damage your headlight, and can not prevent the power pack from failing. In other words, if the power pack has a problem, it will fail dosen't matter where you put it. And I find that really hard to understand how the failed power pack will damage your headlight (physical damage??) other than if it catches on fire or blowing up (which if there is a capacitor in the power pack, it's possible). If it's just short out than the 2A fuse should take of damaging the circuit. What difference is it going to make by leaving it outside if it's just shorting out?? I think we deserve a better explanation, or at least tell us what happened. Last edited by ULTM135; 05-25-2010 at 02:03 AM. |

Temp in the headlight housing vs engine bay
So after some search in the M3 and E90 post, I found NA Motorsports' and Marc's explaination as follows:
NA Motorsports: "The temperatures inside the headlight assembly are hotter and a more confined area than the engine bay. Also keep in mind that the headlight assembly has no way to dissipate the heat properly. So the power supply was over heating. Removing the power supply from the assembly will stop the over heating issue." Marc: "As for the fix, With the testing that was done, we concluded that the failed power supply had overheated inside the headlight, causing damage to one of the chips, which then malfunctioned. Moving the power supply outside of the headlight and putting an in-line fuse will fix this 2 ways. It will prevent the chip from getting damaged because it will not be exposed to these temperatures, and as well the fuse will act as a safe-guard." So, is the engine bay's temp really cooler than the inside of the headlight housing?? Let see... I happen to have a thermometer with a dual thermocouple that can take 2 temp readings at the same time. The large number display corresponds to the thermocouple I hold in my hand (the orange tag), the smaller number display is the one I am not holding. Last edited by ULTM135; 05-25-2010 at 01:40 AM. |

I put the thermocouple with the orange tag external to the headlight housing (the engine bay) where it's a reasonable place to put the power pack outside the headlight housing, and the other thermocouple inside the headlight housing.

Let the engine idle for about 15 mins...the engine bay temp went up to 80.2 C and the inside headlight housing read 60.4 C. Now keep in mind, both AE and Xeon lights were ON the whole time.

I am sure if I keep driving or the ambient temp is hot as in a hot sunny day, the engine bay temp will get even higher. And given long enough time, say 2 hours, the temp inside and outside the headlight will be about the same because the heat source is from the engine/radiator. I did measure the temp of the LED heat sink and it was 91 degree C, which is a lot cooler than the engine/radiator. But the point is, THE ENGINE BAY TEMP IS DEFINITELY NOT COOLER THAN INSIDE OF THE HEADLIGHT HOUSING. When I finished with the test and try to open the headlight housing, my hand almost got burned by the "bitch clips". That how hot it gets in the engine bay. SO IF YOU THINK IT WILL BE COOLER LEAVING THE POWER PACK OUTSIDE THE HEADLIGHT HOUSING...THINK AGAIN!

Oh...but I did remember reading somewhere that NA Motorsports said that the LUX H8 / 1 series failure rate is like 0.5%, or 99.5% reliability. That's better than 4 sigma (as in Toyota suppose to be the 6 Sigma company). I mean how do they know those failed Lux LEDs are not just normal defects?? I think they just shot themselves in the head by recalling those lights. 99.5% reliability, that's better than BMW's HPFP, isn't it?
 Recall HPFP...anyone??Last edited by ULTM135; 05-25-2010 at 02:33 AM. |

Had the lux bulbs installed for about a little over a month and loved them. Took them out last weekend to send back for a refund with plans of getting HIDs (back to stock for now which looks awful). While removing them I noticed that the power converter was right where I left it, by the DS1 headlamp and the arm that moves the headlights.
Reading this thread makes me want to reinstall them. I don't want to go through the hassle of installing HIDs and I don't like how uneven they are. Plus I live in a very humid area and I am concerned about the seal. How much risk is there if you are very conscious of where you put the power converter? Does anyone here plan to leave them in despite the recall? Why is the old converter box not subject to the same issues? |

For Red angel eyes, honestly i wouldnt bother because first off they are illegal and you will get pulled over instantly. Also, there are no Red LED's that are bright enough to really be seen. There are some red LED's out there, but nothing with enough output to be seen during the daytime, and barely at night
