danielsternlighting.com is where I got my information from, and he sells the bulbs as well.

Thanks for all the input.
I found this:

"For reference, here's manufacturer data*for output and lifespan at 13.2v for standard-wattage H1 bulbs.*The numbers here are a composite of values applicable to the products of*the big three makers (Osram-Sylvania, Philips-Narva, Tungsram-GE). Each*manufacturer's product in each category is slightly different but not*significantly so. *I picked H1-type bulbs for this comparison, and while*the absolute numbers differ with different bulb types, the relative*comparison patterns hold good for whatever bulb type we consider (H4, 9006, whatever).*Lifespan is given as Tc, the hour figure at which 63.2 percent of the*bulbs have failed.

H1 (regular normal):

1550 lumens, 650 hours

Long Life (or "HalogenPlus+")

1460 lumens, 1200 hours

Ultra Long Life (or "DayLight")

1430 lumens, 3000 hours

Plus-30 High Efficacy (CPI BrightLight, Osram Super, Sylvania Xtravision, Narva Rangepower,*Tungsram High Output, Philips Premium):

1700 lumens, 350 hours

Plus-50 Ultra High Efficacy (CPI Super Bright Light, Philips VisionPlus, Osram Silverstar, Narva*Rangepower+50, Tungsram Megalicht, but not Sylvania Silverstar):*

1750 lumens, 350 hours

Plus-80/90 Mega High Efficacy (Philips Xtreme Power, Osram Night Breaker):

1780 lumens, 340 hours

Blue coated 'extra white' (CPI Bright Light Blue, Osram CoolBlue, Narva Rangepower Blue, Philips*BlueVision or CrystalVision, Tungsram Super Blue or EuroBlue, Sylvania*Silverstar or Silverstar Ultra,*also PIAA, Hoen, Nokya, Polarg, etc):

1380 lumens, 250 hours

So that's the pattern for how lifespan and light output are related. It's worth noting that the lumen differences are not the extent of the performance differences. The filament changes required to make a long-life bulb tend to reduce the beam focus, which shortens seeing distance. And, the light color is less white and more brown. But lifespan is lengthened. The opposite filament changes are made to create the "Plus" (+30, +50, +80, +90) or Osram "Hyper" type bulbs: Lifespan is reduced, but the beam focus is better so seeing distance is longer. Light color is whiter and less brown. The takeaway message here is that even if all the filaments put out exactly the same amount of light — the same lumens from a long life, a +30, a +50, a regular, an ultralong-life, etc. — the headlamp performance and appearance with the long-life bulb would still be inferior compared to the same headlamp performance and appearance with a regular, or +30, or +50, or +80, or Hyper bulb.

The various H1 bulbs can be browsed here."



Think I will probably look into getting the Philips Xtreme Power or Osram Night Breaker. Seems like the best for good head lights. I think thats a good chart to look at for reference when wanting to know what kind of headlight to get though.

 

Do they even sell the Philips Xtreme Power as 9004?

 

I found that out online when I was looking for bulbs. I could NOT find the osram silverstars around here though.

I ended up buying GE nighthawks (more of a yellow light, it rains alot here).

I run hella 80/100w Xeon bulbs in my truck, online they are CHEAP!

My girlfriend has the Sylvania silverstars in her 95 runner, but my lights are much better

 

Any idea?
