Like John said (he's always on top of these things), I can't offer you much. You have the products. You sell the products. I don't. All we can do is tell you what we see as a problem with the method of marketing and what is missing from it.

Ok we have a solution here. I have been in PM with n3elz and here is an exact copy paste of what we are going to do

And I will go you one better: if I like them, I'll pay you your normal price for them -- in fact I insist on that to avoid conflict of interest problems.

I will also test their electrical draw and inform you of the results.

I appreciate the opportunity, and I again commend your strong stand! I am impressed despite myself!

Would you like the fact that I'm testing them to be confidential? I have no problem with "challenging" me to test them and going along with you on it in a public post, if that suits you. Your call.
Exact conversation his lights will be shipped by end of week. I will be sending him these http://www.image1000plus.com/store/v...php?product=06 to test which are the "expensive" ones I sell

Haha. Seriously, that is a good idea. John is an honest guy and his head is exploding with information.

Yeah, if you did that you'd be like Bose.

And it will be swelling even more if you keep that up, lol!

I think this is a great way to resolve this and I'm looking forward to quite possibly finding an inexpensive source of improved headlight bulbs. I'll let you all know.

Very cool resolution to this issue! John's got the equipment, know how, and experience to probably put a set of bulbs through a pretty good set of tests and tell you/us exactly what's going on w/ them. He deserves credit for even volunteering to do such a thing. Personally I'm not so sure I'd volunteer my time & effort like that. .. But then again, I have been labeled 'the a$$hole of the Internet' before!

Okay, my test procedures will be as follows:

1. On a day with stable temperature, run the factory headlights and record current drain, and starting and ending temperatures of the headlight connector using an optical pyrometer. I'm thinking a 15 minute run should be adequate to heat things up pretty good.

2. Same day, same conditions, after allowing everything to return to ambient temperature, I will do the same tests with the new bulbs and record the results.

3. I will take my digital camera and put it in manual exposure mode, and force the white balance to daylight. I will take pictures of the light pattern with the new bulb in one side, and the old in the other. This should allow an apples-to-apples comparison of brightness and color difference. (Question to Colin and others: should I use a tungsten setting instead? Perhaps I should try both tungsten and daylight? Please comment).

I wish I had a good light meter to check luminance with objective measurements, but I don't. So I will just do the photo test. Other testing ideas? I'm open to suggestion.

I will also post my subjective feelings about them after driving with them at night as well, but they will be just my impressions is all.

One correction he didn't volunteer, I PMed him and asked him for his addy so that I could send him a pair for free

And actually, I get a kick out of testing things, so this works for me on many levels. I just think it's more ethical for me to buy them if I keep them, though I appreciate the offer.

I would think you'd be able to wire up a pretty good test setup indoors, in a relatively temperature controlled room. A fairly stable high-amperage supply mated to an excessively over-gauge wiring harness w/ a meter in the works. Measure the current draw as accurately as you can. Maybe that fany-shmancy IR temp meter off the bulbs directly, that's certianly be interesting to compare. Do a baseline w/ the stock (or similar) bulbs and compare.

As for taking photos, maybe find a fairly white wall and fabricate some sort of projector assembly. Maybe from a junked Ranger headlamp assembly.. Then set the camera up full manual on a tripod, use the same settings for both bulbs obviously. Yeah, I would recommend either the tungsten setting, or a manual WB setting on the camera, if available. Certianly not Auto! It would be interesting if you had a camera that would shoot true RAW files as they often have better dynamic range.

To be honest white balance/color is my weakness w/ photography. I'm still trying to figure out exposure.. But if you have two shots w/ identical exposure & WB settings it should be fair to compare them. Maybe we can measure the light thrown somehow and measure the color temp of the light.. I'll ask around.

Christian PROBABLY knows I don't have 9005 fogs anymore. I have little cheapie ones with 50 watt H3's in them.

And yes, 9007's, thank you.

I'll ask around.

Those are some good ideas. I'll probably keep it simple and "directly relevent" for now by testing them in the truck and not on a bench.

I'll use a clamp on ammeter and get readings just to the nearest 0.1 amp or so. Really, what we're looking for is that the light has, say, and 8 to 10 amp draw rather than the more normal 4 to 5 amps. That could be resolved without a great deal of accuracy. I'm not sure how consistent bulbs are anyway. The goal here is to find out if they are grossly overpowered.

Temp also needs to be measured as close to operating conditions as possible. I will measure the back of the socket, atter quickly pulling the headlight out (I'll have undone the latches before the test).

The actual bulb temperature is EXTREMELY difficult to measure accurately optically for this. The emissivity of glass is quite low, and the filament's radiation is tough to keep out of the field.

I could measure the filaments if they are not too hot, but they may be. The equipment I have available has a maximum range of 5000 F -- which is pretty hot, but they may be hotter and probably are.

The uncertainties of those other tests, though they would be interesting and maybe informative, lead me to avoid them and "keep it simple".

I'll try a couple of different things then with the photography, and thanks for the comments.

An aside, Xenon is not a halogen gas. These results should be interesting.

It's a noble gas. But don't question his light bulbs or he'll start PM'ing you.

My My aren't we touchy about someone PM'ing you. I did it because I figured you'd act like a baby if i did it publicly.

I stand corrected. That's what happens when engineers talk about chemistry from memory, instead of looking it up.
