And you never know if there are other "indexes" that would need to be tweaked

On a slightly off topic note, my hir1 highs have been running at 15.2 volts for at least two years and are still going strong. This is surprising because increasing voltage has a logrithmic effect on bulb life and they should really not last long at all.

High beams are also used for maybe 5% of the car's nighttime driving. There will be exceptions to this, of course. Given that statistic, using a brighter, shorter-lived high beam makes sense.

This is off of the web site that I posted for the HIR bulbsLeSabre in Buffalo wrote:Go with the HIR2/9012 for the low beam. The small difference in light output is far outweighed by not replacing expensive HIR1/9011 bulbs every 6 months. And, the HIR2/9012 has the filament in the exact same spot as the 9006, or at least close enough to be unnoticeable. I can't say the same thing about the HIR1/9011.
Philips HIR2/9012's have a lifespan of 1500 hours or something crazy. The HIR1's have a lifespan of 150-200 hours. If you drive a lot, 150 hours is about 6-9 months. At $50 a set, HIR1's in low beams would get expensive really quickly.
Toshiba 9011/HIR1/9005 65W Halogen Infrared Bulb
• 3000 Lumens
• Design life 1400 Hours
• Light Color 3450 Deg. K
Toshiba has discontinued the manufacture of this bulb and sold the technology to Phillips. Supplies of Toshiba Busbs are now exhausted. Phillips has tooling up to produce HIR1 bulbs of a updated technology, which makes them even brighter and longer lived.
So it looks like Phillips made the HIR 1(high beam) last longer than the original Toshiba design.

In general a 5% increase in voltage will translate to a 50% loss of life. On the other hand, the lifespan of a 9006 lamp is based on 14 volts, while the output is based on 12.0 voltsyourgrandma wrote:On a slightly off topic note, my hir1 highs have been running at 15.2 volts for at least two years and are still going strong.

I have seen nothing that shows that the Philips 9011/9012 are actually HIR bulbs. I have seen plenty of posts on other forums that say they are nothing more than boosted 9005/9006 bulbsrrounds wrote:Toshiba has discontinued the manufacture of this bulb and sold the technology to Phillips.

Yep, phillips 9011/12 barely make the standard for the form factor. they use the maximum power and produce the minimum output.
That is unless something has changed. I wish I would've bought a few pair of 9011 when they were more easily available. When mine burn out my only option will be a quad retro.

I had a set of Philips HIR2 bulbs and a set of Toshiba HIR1 bulbs side by side, and the Philips HIR2's definitely had the HIR coating on the inside.Mad Myche wrote:I have seen nothing that shows that the Philips 9011/9012 are actually HIR bulbs.

The Philips HIR1 bulbs are an overboosted 9005, again from what I've read.

But i know otherwise

I only sound disapointed because it would be a huge undertaking for a marginal improvement. I've always fealt that highbeams should involve additional lighting elements to strongly differentiate them from the lowbeams.

You have a grille , hide some driving lights back there. Leds are getting pretty bright nowadays

I used to have my blazers in there but I didn't like the looks so I mounted them in the stock fogs. I've been considering the possibility of an led highbeam retro. Thermal management would be the biggest issue.

I havent seen in behind the headlights on an s2k , but most of the guys on hidplanet , are using PC heatsinks i believe.
What are you gonna do for optics?

There are a few options for snap-in lenses or reflectors. Id be most worried about making an aesthetically pleasing setup with good thermal properties while remaining somewhat weather resistant. I cannot recall exactly how much led power it will take to beat my boosted hir's but it will be no small feat.

I believe the brightest most effecient led right now is the cree XM-L.
Making around 1000LM.
How much light do you figure your HIRs are making?
Ill make an aggressive guess at 4500lm each for a total of 9000lm.
Meaning you would require 10+ LEDS to be brighter.
You could always retro these into your highbeam spot for a clean quad look.

You would need to boost them , but since they would be highbeams no concern about bulb life anyways. Throw 100watts at them for 18,000 lumens ( with phillips DL-50 bulbs)

4500lm a side is probably about right. The hella driving lights are nice but I don't want hid for the highs. Otherwise id just run a pnp kit in the highs. Warmup time makes them useless for that function though. Even my denso ballasts (the fastest startup that I am aware of) would be too slow for highbeam use.
4 or 5 xmls per side wouldn't be too horrible to manage, so long as I could get rid of all the heat.

Of course , the real trick being making the install look clean.
