Okay, my attempt here to is write a review, or my opinion of these lights. I took a bunch of pictures, but all that showed up is the lower part of the beam (see crappy hand drawn image of the Eurobeam).
I recently picked up two 4" Rugged Ridge (or whatever name they're using - fairly generic) HID driving lights. I also picked up two 7" lights. They all have the Euro beam pattern (see pic below). I first hooked these up on the weekend, and wasn't too impressed. But decided to take them to the rifle range tonight to give them another chance before dumping $1150 on some Hella HID lights (I was looking at the Hella Rallye 4000i - compact light - $375 USD each). I'm now thanking my lucky stars that I didn't get ahold of the sales guy this afternoon, as I've reconsidered making that purchase. I'm more than willing to give these lights an honest chance (will wire them in properly) before even considering the Hella's again.
This is what the beam pattern is:
I've assigned some values just so there's no confusion with the words.
10/10 = great lighting
1/10 = very poor lighting
Ok, now to what I found out. I initially started off with one 4" light. Using the light, I was able to clearly see the 100 yard markers (10/10), easily see the 200 yard marker (6/10) and barely able to see the 300 yrd markers (2/10) (it's right at the edge of the light and if I didn't know it was there, I doubt I'd be able to pick it out). I'm sure if you measured the light it would go out much farther, but this is what I can see with this light (so useable light). This is with one 4" light that cost me $130 ($260 CND for both, including shipping to Northern Canada).
Now on to the 7" light (the 4" was put away). When I first tested these in the field I noticed little difference between the 4" light and the 7" light... Clearly I didn't have a big enough field. Again, I was clearly able to see the 100 yrd markers (10/10), I was clearly able to see the 200 yrd markers (9/10), I could easily make out the 300 yrd markers (6/10), and could make out both the 400 yard markers (4/10) and the 500 yard markers (3/10). Yes that's right... I could see tree's and **** out past 500 yards. I paid approximately $125 CND a light (including shipping to Northern Canada).
To give you some comparison, my 18 mth old Lightforce 170 55w lights could see the 200 yrd markers (4/10) and the 300 yrd markers was right at the fringe of the light (1/10). The light was also the halogen yellow and made things hard to see. And from experience, that in poor conditions, will strain your eyes. Where as the HIDs offered a bright pure white light.
I've attached a picture, but it honestly doesn't even come close to doing these lights justice. This is at the 100 yrd targets. What this picture doesn't show, is that the horizontal beam pattern was quite wide (it covered the whole width of the range when I was looking at the 300yrd+ range). The light on the ground (before the targets) is from the bulge on the bottom of the beam pattern (see above).
Now, after seeing how well these lights performed, I'll not be calling the store back about the Hella HIDs. This isn't because I don't think these lights could be improved on (because there are probably better lights out there), but that for the price of the Hella's, I'm really wondering if the difference will be enough to justify the cost. If I had the chance to do this all over again, knowing what I do now, I doubt I'd even look at the Hella's. My total cost on these was around $500 Canadian. And while I was willing to pay much more than that to be able to see, it doesn't look like I'll have to.
My opinion... if you're looking for some HID driving lights, look no further. These have an internal ballast, and offer a great bang for buck value.
Now after using these (drove from Whitehorse to Edmonton - 1800km), I still value them (and have kept the four 4" ones), but the hassle of aiming these just right (the mounting bolt is also used to loosen & aim the lights), its a real *****. For the short range stuff (less than 250 yrds), they're great, and the four lights I kept when I upgraded from the XJ to the JK will be incorporated into my lighting plans for the JK. However for the longer range stuff (250-500yrds) I think I'll be looking at something else.
That being said, for the price I still haven't found anything comparable, and would still recommend these as a decent & affordable light.
