Yikes. $.33/hr. Then there's the more-frequent replacements (and the higher likelihood of the bulb failing at inopportune moments (as if there were really *opportune* moments)).They give very high output, but have a high price (nearly fifty bucks a pair on Amazon) and a very short life. For example, the 9007NHX is rated 90/150 hours!
WOW! That's pretty awesome! Half the price of the Sylvania XtraVision +30 (a bulb I could recommend getting off the rack at Wal-Mart for someone without time to mail-order a new set of bulbs, but never a bulb I would hotly anticipate getting). Sweet deal!Looks like Amazon is offering a rebate on the Night Hawk Platinum (a "Plus 90" bulb) making them about $9 (nine dollars!) a pair.
That would be interesting. Whose cost/benefit profile? The OEM? The owner seeking to upgrade his night driving experience? (Definitely not the bulb-makers! They'll burn out your bulbs at exactly their "rated life +1hr" if they could.) From the gut, I would say that unless the vehicle already has the premium wiring, there's no sense fiddling with it, and so selection should be based on the bulb itself. Still, a well-fed +120 bulb will be shedding the mortal filament coil quite often!Speaking of data, it would be interesting to see some detailed data on the differences in headlamp performance with (for example) long life, standard, Night Hawk, Night Hawk Platinum, and Night Hawk Xenon, at a range of voltages. I would like to see what voltage you have to run the lower-output bulbs to get comparable performance to the higher-output bulbs. Then it would be possible to see which has the better cost/benefit profile: premium bulbs on standard wiring or standard bulbs on premium wiring.

If only there were a REAL and GOOD ballasting system that could be used to dial in a specific voltage with precision and with a ramping up from a lower starting voltage to the set voltage (so the starting shock is reduced)
I meant to say that unless the vehicle DOESN'T have premium wiring. Or that if it did, then don't fiddle with the wiring. Oops.I'm not sure I follow you. What do you mean by this?
Truck-Lite used to offer just such an item about ten years ago, a headlamp life extender that provided soft-start and regulated voltage of 12.8v. See old pages here and here and here. The product is no longer offered; apparently demand wasn't sufficient at the (rather high, as I recall) price point.
(Amazon's parts catalog database does seem to be full of errors and omissions.)
Holy crud, that's a great price! (link is here). Either a mistake or a super-duper sale. Whoever uses H4 or 9003/HB2 should grab up a bunch of spares before the price goes up again.
