H4 led headlight bulbs

[RSBob]

[craigerz]

Went directly to siriusled.net and they show a number of different generation products, I emailed them and they wrote back telling me of a new 7th generation bulb. Sirius LED - 7th Gen Philips ZES LED Headlight
These are non fan bulbs, specs are very high and they are made by Phillips. They are rated at 4000 lumens each, 8000 total, 6000k pure white, but come w/ stickers if your into that. Probably going to get a set and try them out. If I do, I'll post results.
Cost is 109.99
Should get paid for this endorsement...lol

UPDATE: I did pop for a pair just now. One other nice thing, free freight!
I'll give an evaluation in a few days.

I ordered the same lights as Dick and Grant after seeing them installed in Grant's car. Hell I've spent more money on a badge so I guess this is worth a shot.

Now when I get around to build my dream 911 it will have the same lights as the Singer.

[craigerz]

As mentioned, I got a set of Phillips Gen. 7's from Sirius led @$109.99 and no freight. Shipping time was 2 days from Frisco to SLC.
Very nicely made, impressive quality. the little 'boxes' that connect them up and run them were about 1/2 the size of a deck of cards, the heat sinks used a bit of Teflon on the threads where they screw on. Incidentally, to make them fit in the housing buckets, you have to reverse and flip over and have the small end of the heat sinks stick OUT to get them to fit in the housings. After reversing them, the fit just fine.
The instructions are not the best however, You can rotate the bulbs in the housings via a set screw, and you want to set them up like the 9004 bulbs were with the shield covering the bulb so light is blocked down. there are 2 little tabs covering the front led's and those need to be rotated to be on top to make the outer 2 led's shielded down. The instructions show how to loosen the set screws, and the range, but not where to set them. Again, set them so they are covered and shielded in the down position.
Now for the good part. These make the best quality light and pattern I have ever seen. Lows are incredible in coverage, but NO ONE blinked me down. When you turn on the highs, it just adds to the lows as they are not turned off. Simply the best lights I've seen, and for the price of $109.99.
So other than the instructions, well worth the money. They are guaranteed for 1 year, 30 day money back, and have a life of 30,000 hours.
The only other thing I'd recommend is to tape a good, heavy bath towel underneath the headlight buckets on the fenders, that way you won't get any scratches from the capsules being changed over.
So, I love 'em and will probably put in some fogs as a project down the road.

Are you running stock relay & switch? From what I understand the LED draw much less, another beni??
THX

[craigerz]

Just running the stock switches and wiring. The Led's only pull 35w, the Halogens that came out were 55/60w each.
And the light that is put out w/ this brand is fantastic!

I know every knee jerk fiber in everyone's brain always goes for new, New, NEW!!! But an HID style 6000K bluish light doesn't give the depth of view of a 3000K more yellowish light. Blue just is a more glaring light.

I have been running an "all weather" 80/100 H4 for for more then a decade and when you question people they think it isn't as bright because it is yellowish but when you ask for details they can see more with them. Your vision has better depth perception which is obviously key. To oncoming traffic the warmer yellow light isn't as glaring and I have never had anyone flash a high beam at me ever.

As soon as someone starts selling a 3000K or 2700K LED H4 replacement I will give it a try but until then ...

[Tremelune]

Well. Citation needed. This is pretty endlessly debated. You don't see many yellow fog lights or ski goggles these days, and there is a reason:

HID colour temperature

OEMs seem to go for about 4300K for HIDs, and I'm willing to bet they've done some research.

http://www.gerontechnology.info/Journal/Proceedings/ISG08/papers/036.pdf

"From this figure, it can be seen that there was no difference between color temperatures of 3100 K and that of 4700 K."

"There is no relation between visibility and the color temperature of a headlight."

Most importantly, there are no H4 replacement LEDs that will improve visibility without impairing it for other drivers.

Apparently not as much research as you might expect. I just saw this story on the local news the other day and finally found an online reference to it.

New IIHS ratings show most headlights are lacking

[Quicksilver]

4300K is WAY more acceptable then 6000k. If you look at the spectrum sensitivity of the cones in the eye it is pretty apparent that biasing the light towards blue is ignoring the fact that the green and red cones have a great deal of overlap. It only makes sense to use a light that is biased towards registering with more of the cones.
But 4300K H4 LEDs aren't available either...

BTW - Never said anything about yellow lights. I said yellowISH lights. And when using a completely subjective method of "Just asking people" they generally respond that the high powered lights, biased towards yellow, don't seem as obtrusively bright as the general "white" lights or "ricer bluish" lights. The more light I can throw downrange without bugging people the better.

-------------
Also - Just because the government studied something doesn't mean they didn't miss the point of it.
All of the research for headlights is based on how much light is being emitted. They have never looked at how it is being emitted.
- Example: Say you have two lights that emit the exact same quantity of light in exactly the same pattern. One light has an emitting area the size of a quarter and the other has an emitting area the size of a dinner plate.
Which one will be more glaring to oncoming traffic?

And that is the biggest problem with HIDs...

I ordered the 7th gen from siriusled thanks to this thread and installed them last night.
I may have a bit of tinkering to do in order to get the cutoff to be perfectly horizontal, but my question is the following:

With the heatsink taking up some good room in the headlight bucket and the fair amount of wiring now being stored in that same bucket, are you guys worried about the heatsink contacting the wiring and potentially melting it?

Here's a pic of the LED H4 vs the halogen:

[craigerz]

If you make sure the wiring don't touch the the heatsinks, you won't have any trouble. I can't imagine them getting any where near hot enough to do any damage.
I set mine up so that the little 'eyebrows' that were over the top of the 2 outboard LED's, which keeps the light coming off of them shining upwards. If anyone else has the 7th gen Phillips LED's from SiriusLED and has rotated them differently, I'd be interested in their opinion. But as it stands, I've been extremely happy w/ the results of mine so far.
People can say whatever they want as to the yellow of halogens and being able to see better than the Whites the LED's produce, and about how other drivers find it annoying, but I get "0" flashdowns from other drivers, and if I can see better, which I know I can, I'll run 'em.

[madmmac]

I am very happy with my led's. I tried multilple wattage halogens along with the relay but these put a shame to them.

These are the ones I got, but it looks like they have another one now also. I know the owner. These guys are legit. Check out their website and Facebook page.

3800 Lumen H4 LED Headlight bulb

They might give you discount if you mention Mitch, Rhianna's dad with the Porsche recommended them. Or they might charge you more!!

Thanks for the reply.
I placed the wiring as best as I could in the bucket, but I'm not sure if when in place it'll end up making contact. Either way, I don't drive for very long at night so like you said, it shouldn't be getting too hot in there.
I have my 'eyebrows' placed the same way btw!

[jac1976]

Can you guys post photos of the actual headlights in situ? As I understand it, these are just bulb replacements, not full Singer-esque Millennium Falcon assemblies. I would not want them to look out of place on my 73. I generally hedge toward function over form, but this upgrade may be form=function. Most of the driving I do at night is in well-lit areas so the headlights may need to little more than make me visible to other traffic. Thanks for vetting these bulbs and sharing with the forum.

[boxcarracer]

If you have fluted lenses you won't really see the bulb.
I'll get proper pics of my car with the LEDs up by the end of the week.

With only 55w/60w they seem to outperform virtually all the other bulbs. They do mention that lifespan is shorter than
,most other bulbs (approx 450 hrs), but if they really perform like they say, that's a small price to pay

Amazon.com: Philips X-treme Vision +130% Headlight Bulbs (Pack of 2) (H4 60/55W): Automotive

I removed the LED bulb replacements that I talked about in a previous post in this thread. At first blush, I was dazzled by the amount and brightness of the LED replacements, but then after doing a large amount of reading in the Candlepower.net website I did some rethinking. They BY FAR recommend the Phillips X-treme +130 bulbs listed above.

So I installed them in place of the LEDs. Great improvement overall! These bulbs at
55/60 watts are brighter than 80/100 halogen and reach out much further (130% further), also they are 3700K color.
To test, I installed one LED bulb and the Phillips Halogen in the other and set off at night for a test. I stopped in a large shopping center and alternately covered one light or the other on both low and high beam. The Halogen reached out further than the LED with a more focused high beam, whereas the LED was rather diffused with TOO MUCH of a localized "splash" of light nearer the car which compromised me being able to see long distance as good as the Halogens . On low beam the LEDs had virtually NO cutoff whereas the Halogens were perfect. I think what makes the difference is the geometry is CORRECT between the Halogen filaments and the reflector. The LEDs are not correctly placed vs the reflectors and in fact CAN'T BE due to LED inherent design. The halogen filaments glow 360degrees where the LEDs are flat and just project out 180deg or less. To sum it up, the LED geometry is just wrong! I guess I never appreciated the engineering that went into the original design of the Bosch H4 Porsche light. I also couldn't get used to the 6000k LED color.

To sum it up, after trying both I will be sticking with the Phillips X-treme +130
bulbs in my car! Thought I was an LED convert, but I've been converted back to halogen LOL! The only down side is shorter than normal bulb life than generic
Halogens, but with all that I spend on this car, it's a trivial thing!

I waited for mine from China for 3 weeks, but it was well worth the wait. I was running Sliverstars with a relay and these LED's put them to shame. Definitely worth $40.00.

I popped in some 7th Gen Sirius LED's in my '75 Beast. Love the light, they are in Euro H4 housings. Amazingly bright...I have the same wonderful results as above....just remember the quote above is a must. I had read this thread (which is why I bought them) and missed this key piece of info. So I initially installed them without a heat sink....and tested them for a few minutes. I then re-read this thread and re-discovered this gem on info.....which then had me pulling and re-doing the lights. I am not sure running without the heat sink for a single evening test drive would have hurt them.....but REMEMBER THE ADVICE ABOVE and all will be well in your LED Headlight world.
