So according to that guys BS, regular halogen bulbs reign supreme over everything else on the market. I've read his information on most of his page before, some of it is dead on true and some of it is very subjective. One thing that I agree with him on is that HID headlights don't always produce good result when placed in a halogen styled headlamp assembly and that they HID perform better when used with projector styled headlamps. But, his take on PIAA versus stock halogens and that stock halogens actually produce the same or better the hyper white headlamps is purely subjective. On paper a lot of what he says is true, but in the real world when you place PIAA's against stock headlamps. The PIAA's clearly give off more light and you'd have a very difficult time convincing anyone that stock headlamps perform better than aftermarket headlamps.

I hate to disagree, but what the guy says in his write up is correct: stock bulbs will produce <i>more</i> light (quantitavely) than a bulb that is coated with a filter. "The laws of physics are the laws of physics", after all. In filtering out the red and yellow lightwaves, the bulb may give the appearance of "whiter", "brighter" light, but that is not the case. I wish I could jack a footcandle meter from school to prove this, but the bottom line is: when you filter anything, you have less than what you began with.
And let's not forget the placebo effect ... When people plug in their aftermarket bulbs, they're <i>expecting</i> to see an improvement. It's hard to combat these expectations with words on a computer screen.
Laws of Physics aside, I still believe that the PIAA's perform better than factory bulbs. You can call it placebo if you want. PIAA headlamps along with PIAA foglamps definately perform better. Especially after the foglamps are reaimed. I agree that those cheap APC bulbs or the bulbs that you can buy a Autozone aren't that great, but saying that all bulbs with a higher Kelvin rating aren't as good or better than stock bulbs is kinda silly. But everyone is entitled to their opinion and you can't definately can't argue with scientific tests. One thing is interesting though, did anyone take notice to him not showing any comparison pictures on his site.(scratch)
