Well.... Ignacio and I are back from testing. My step-son froze his ass off in the brutally cold High Desert canyons while taking 18 different photos of various combinations of halogen, HID, PHIDs and Hella HID.
Here's what every *single* one of them look like:
Well, crap..... :angry: not a single friggin' shot came out... :angry: We're not winning in the camera department, I'm sad to say....
Well, Ignacio and I will just try to describe what we saw tonight. Some comparisons were a bit surprising, though most came out pretty much as expected. Below are my opinions; I'll let Ignacio speak for himself. It was important that I brought him along for this comparison test, because he hasn't had his night vision borked by LASIK surgery like mine.
LOW-BEAM Comparison:
As expected, my one HID Low Beam still provided greater visibility than Ignacio's two 55-watt halogens. Matt suggested my single HID low-beam was about 50% greater visibility then both of his lights together. I concur with his observation. This was despite the fact that my headlights were aimed a bit lower than Matt's (this I had done on purpose when initially installing the HID kit, just to ensure oncoming traffic doesn't get zapped by the intense light)
HIGH-BEAM Comparison:
I thought the down-range coverage was actually better with Matt's twin halogen bulbs compared to my one HID high beam, but again, my one high beam is aimed a fair bit lower than Matt's, so I think this would be a different story if I brought my aim up to match his. What was CLEAR, however, was the fact that the single HID high beam seem to afford
much greater contrast to discern individual objects, *significantly* more so than the halogen. Matt remarked that it was obvious that over the course of several hours of night riding, the HID would be *much* easier on the eyes than the yellowish halogen. We were both struck at how yellow the high-beam halogen looked compared to the single HID high beam.
PHIDs vs Hella Comparison::
Here was the surprise of the evening, at least for me. We compared the PHIDS vs the Hella FF200 HIDs, and there was simply NO comparison at all: the Hellas were *significantly* superior to to the PHIDs in both downrange and periphery coverage. I suppose this shouldn't be a huge surprise, given the big, honkin' 5.5" diameter reflector housing of the Hellas. But I tell ya what, it was most definitely noticeable how much more light there was with the Hellas over the PHIDs.
Well, there it is, folks... 'tis a bummer we couldn't get the photos to come out, but there's the comparison from my perspective. I'm sure Ignacio will chime in here shortly and provide his opinions on the comparison test.
