Some of my PIAA bulbs are over 4 years old and look just like the newer ones we use.
You never lose when you buy quality.

This is true but the PIIA's only have a 1 year warrenty and the cheap ones have a lifetime warrenty.

Perhaps so, but if the measuring life in "lifetime" is that of the bulb, then the warranty will expire at the very moment that the bulb burns out.............at that moment - it's "lifetime" is over!

Trust me - this is the way that lawyers (and the people who write warranties) think.
 
Never had a PIAA go yet but have seen plenty of others go. As they say, it is what it is.
 
I should add: we got turned to PIAA for snowmobiling which is way hard on light bulbs. Every guy and his brother in the business has a "great cheap bulb" 'cause sleds really go thru them. Not the PIAA bulbs. That's our experience with sleds and bikes. I much prefer to change them one time in my garage than out on a trail at -20 or at night on the side of the road in the rain. YMMV though.
 
Your are right that its hard to go wrong when you buy quality. However if there is a product that does the job just as good as the high dollar item but does for half the price, then I will go with the cheaper of the 2 if it does the same job. But in this case you can buy 3 sets of the cheap ones that are lifetime warrentied for the cost of one set of the high dollar ones with the one year warrenty. Now there is something to be said about first hand experince. That is the reason I asked for some of you guys in put.

But if the PIIA has a 4000k rating with a one year warrenty for 75.00 or the H4's with a rating of 8500k with a lifetime warrenty for 25.00.
Even though I might be able to drive a Cadillac, I drive a Chevy because it gets the job done just as well. Just my 2 pennies worth.

I don't put much faith anymore in most manuf. claims, ect. The only real way to know is to use stuff and see how it works. 10 years as a professional SCUBA instructor and NOAA research diver-well I've seen every make and brand of SCUBA gear and lots of stuff that was "just as good and cheaper' but I never saw a professional use any of that stuff 100 miles out into the ocean.
If you get those bulbs-run an extended test. Having several contacts in manufacturing (steel, clothing, electronics) I've been with several QC departments. All real world guarantees and such are the product of statistical analysis and I'd be shocked if any bulb manufacture of an H4 bulb, which is filament based would offer a lifetime claim.

Not wanting to start a "he said she said" here-just after 52 years of being around a lot of this stuff one gets, shall we say, a bit jaded with some manufactures claims.

All in all, though, it's just a bulb, eh?
 
The 8500K vs 4000K has nothing to do with life of bulb or how much light it puts out. It is the color of the light when you look at the bulb. Natural sunlight is in the 4-5000K range. HID light look blue because that is the temperature of the gas arc, to make an H4 bulb look blue the light is filtered so ther eis less actual light output unless you use a higher wattage bulb.
