HID retrofit discussion

[sleepydsm]

holy! ppl he's just trying to get every one a good deal on them, if you are worried then pass on the sale! it's a simple as that

Agreed.

When I am talking about sampling frequency, I am referring to how often is the measurement device taking a measurement. I have found a couple different multi-meters at work that do not sample fast enough to catch the initial current surge that HID ballasts have. That is why I ended up using a current transducer with an oscilloscope.

My DVOM is has a High sampling rate, with a Min max function, so If the readings are below 10A I will catch it, or blow my fuse, we will see Ill get it done soon.

I have the ebay black housing headlights, with the hids..wired wrong when I got them, but fixed it, and it works just fine now. Yet to have any issues.

Results...
incandescent bulb(9006)
*surface temp #1 -857 degrees
*surface temp #2 -913 degrees
*surface temp #3- 970 degrees
HID Bulb(H7)
*surface temp #1 -658 degrees
*surface temp #2 -738 degrees
*surface temp #3 -823 degrees

Conclusion:
HID's run cooler than Incandescent's

I need to question this method of measurement. Did you use an optical temp sensor, like infrared stuff? If so, this can't possible represent the actual temperature of the surface, you could just as well be measuring the temp of the filament in the incandescants, and the gas or whatever it is in the HID's. You need a non-optical reading for surface temps of glass.

My guess is that it will be very different (lower for both). If my headlights are reaching 900 degrees, my car would have caught fire a long time ago.

And it was already addressed, but I would think poor wiring would be the culprit, not the bulbs or ballasts themselves.

agreed to the point of accuracy, just to prove the point that the HID bulbs run cooler,

Did you ever get around to this test? This thread is making me nervous about the 55w DDM kit in my Bimmer. They sure do spark bright when turned on...
