Firstly, this is a cross post with an older set of posts, which I think is closed. My Question:
I have recently installed a) 2 IPF XS900 "Spot lights" to my car with TOTALLY DISAPPOINTING results (even a set of Narvas would have been a 500% improvement!), b) 2 IPF "spread beams" which greatly improved my belief in IPF lights, and c) mounted 1 "spread beam" and 1 "spot light" (which confirmed my DISAPPOINTMENT in IPF Spotlights.
The problem may be a "batch" problem but the "spot lights" had a VERY DISAPPOINTING pattern. The pattern had a small "hot spot" in the centre with a fairly dim halo around it and a "finger" of shadow up the centre of the road leading to the "hot spot".
I initially changed these lenses for the "spread beam" lenses which were EXCELLENT! though a little disappointing for their "reach" (naturally).
So I bought a single "spot light" lens and installed it (thinking that it may have been misaligned by me originally), but with the same DISAPPOINTING pattern resulting in the DIMINISHMENT of the total light output of the 2 "spread beams" (exit 130W of "spread beam" overlaying the single "spread beam") and no noticeable improvement in the "reach" of the lights.
I am now in discussion with ARB as to where I go from here. Note: I had excellent response from ARB on my first contact.
I expect that I will go back to my Hella's or my Bosch's with which I have had satisfactory performance in the past. I may even try Cibie Super Oscars which have had an excellent reputation for many years.
As I have said, the IPF "spread beams" leave nothing to be desired except "reach" (which is to be expected). But my experience of the "spot lights" is TOTALLY DISAPPOINTING!
Can anyone else comment on their experience of the "spot lights"?
