Gregor81 je napisal/-a:Malo off-topic: sedaj že dva meseca vozim avto s ksenon žarometi (tovarniški) in v nobenih okoliščinah ne opazim kakšne drastične razlike glede na halogenske, ki sem jih imel prej. Majhna razlika seveda je, a sem glede na razliko v ceni pričakoval "revolucijo".

Mi lahko kdo od poznavalcev pojasni, v čem je prednost ksenonov za povprečnega Janeza Novaka?

J.McLane je napisal/-a:No meni sta zdaj po 2 mesecih pocrkali obe žarnici H11 NB unlimited, kar se mene tiče je tale (drag) eksperiment za mene zaključen dvomim, da je avto kriv ker so originalne delovale več kot 4 leta.

Ima kdo izkušnje z garancijo? Embalažo sem žal že zavrgel.

No takole se je razpletlo, garancijo so mi (po njihovih besedah izjemoma) odobrili in danes sem dobil dve novi žarnici. Bomo videli koliko časa bosta zdržali ti dve.

J.McLane je napisal/-a:Malo sem preračunal in sem prišel do neke ocene, da so svetile vsega skupaj ~70 ur. Tehnične specifikacije pravijo, da svetijo od 150 do 250 ur pri 13,2 V. Morda je taka življenska doba za 14,4 V čisto "normalna".

Sedaj imam Hella za 6 eur, me res zanima koliko časa bodo zdržale.

"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.
