Another LED Headlight Question

19063 Views 87 Replies 17 Participants Last post by  IM0001
Looking to upgrade my headlights. After reading many posts ..... I'm more confused than ever. Lots of links to products no longer available etc....

I'm never sure which ones fit and which ones do not. I bought a pair that fit my son's Cobalt(?) but they didn't fit my Volt. I have a '12.

Anyway, would one of these work? Which one? H7?, H11? I'm kinna sick of looking. around.

Any help is always appreciated. Thanks.

They aren’t actually 4000 lumen, just a heads up. The ones you have I very much doubt they are 2500 either. Offshore LED bulb swaps are incredibly inflated.
Turboguy327, We've had our disagreements in the past, but on this I agree 100%.
Most of the assembly companies use RAW data from the LED chip maker and real world output is usually around 85% of that.

There do seem to be a few exceptions that list more realistic numbers.
That's okay. The last set were an improvement and if this set is another improvement I'm fine with the $69 I just spent.

What is it with you and LED headlamps anyway? You seem to have issues.
Because they are a waste of money. If you upgrade the halogen bulbs, it will be a much improved upgrade over a Chinese LED bulb swap. HID and LED belong in housings designed for each light source. I’ve proven it on the Facebook page more than once. With volt projectors

And it drops even more once refracted through the headlight optics that where not designed for it and are very inefficient at distributing light from LEDs.

Glad we can finally agree on something.

And what about halogen output claims?

I’m not sure what your question is?

I don't want to take anything away from your findings. Are you saying I haven't seen an improvement with my car?

Idk. Have you? I know that upgrading halogen bulbs will give you better results than a Chinese LED bulb swap. Anything is a improvement over stock but you can get halogen bulbs cheaper that will be more reliable and easier to install than cheap LED bulbs. I know they aren’t actually cheap, but they are made very cheaply.
It is nice to see the updates. Specs improving too. Thanks guys.

I did a halogen upgrade. I'm not really interested in HID, if that's what you're talking about.

Did I see an improvement with LEDs? Yes, to my eyes anyway. I'm quite sure what I did wouldn't be better and possibly worse for other people, especially older folks with yellow eye lenses.

It's not just about lumen output, projector or headlamp optics as I understand. I'm now on my fifth set of 'bulbs'.

But wait, you're quite sure I haven't had an improvement. If you have a case to make perhaps we could see your results here? I'm not a fan of scanning through Facebook posts.

The ones I installed are Phillips brand and a much higher quality of machining and assembly than I've seen from "Chinese LED" bulbs. We can agree that the latter are terrible. Well worth the money for what *I* want in a headlight.

The color is a nice white. Not blue, not yellow, but a nice bright white. Not everything made in China is cheap or junk.

I know. I own a collection of DJI products. LED bulbs on the other hand...

Did you buy them directly from Philips? Or a authorized retailer?

And did the package have 1 “L” on its packaging or 2? Real philips products only has 1 L. Common way to sell forgeries is to have Philips with 2 Ls.

No, other coast-ish.

I'm in Utah.

Just curious, was hoping to compare. I edited my post after you posted.
Our emitter arrays conform to the 9012 halogen filament's position and orientation for maximum compatibility with the optics in a halogen headlamp.
Is this a meaningless claim? If so, why?

Well, I have no idea where it came from so.... And, probably considering that the only bulb that can replicate a halogen bulb.... is a halogen bulb.

I'm not trying to mock you. You were very certain about your post, and now we're at "probably".

Here's the data sheet on the chips if it helps: http://datasheet.octopart.com/LXZ2-5770-Philips-Lumileds-datasheet-41562122.pdf

Now if you know something we don't please share it. I'm not looking for perfect bulbs, but I'm all for having more useful information.

The Phillips brand is what you get from XenonDepot. The box says "Designed in Canada".

Seems suspicious that there is no "eh".

LED bulb swaps just can’t replicate halogen bulbs. It’s a fact. Not a opinion. And I was being sarcastic.
While I'm at it, here's the data sheet on the LEDs in my car right now: http://www.lumileds.com/uploads/447/DS136-pdf

You say. Again, I'm not mocking you or being sarcastic, but I don't take anyone's word in a forum for what a fact is.
