Adding higher output aftermarket headlight bulbs to your Volkswagen will result in a different colour output and additional light but there is a tradeoff and this is the lifetime of the globe.
Based on data from the respective manufacturers the light output (measured in lumens) and lifespan (measured at 13.2v) is summerised below for H7 .
1500 lumens, 330/550 hours
Power Saving – up to 20% power saving
1500 lumens, -/- hours
(Osram Light@Day, Philips NightGuide DoubleLife, Philips EcoVision, Philips Longer Life)
1500 lumens, 450/930 hours
Plus 30 – up to 30% more light
(CPI BrightLight, Sylvania Xtravision, Narva Rangepower,Tungsram High Output, Philips Premium)
1500 lumens, x hours
Plus 50 – Up to 50% more light and 20m longer beam
(CPI Super Bright Light, Philips Vision Plus, Osram Silverstar, Narva Rangepower+50, Tungsram Megalicht)
1500 lumens, 150/220 hours (1580)
Plus 80 – Up to 80% more light and 25m longer beam
1500 lumens, 100/200 hours, 3400°K (1620)
Plus 90 – Up to 90% more light, 10% whiter light and 35m longer beam
(Osram Night Breaker, Narva Blue Power):
1500 lumens, 100/200 hours, 3750°K (1620)
Blue coated – up to 20% more light then standard with bluish-white light
(CPI Bright Light Blue, Osram Cool Blue, Narva Rangepower Blue, Philips BlueVision, Philips CrystalVision Ultra , Tungsram Super Blue, Tungsram EuroBlue, Sylvania Silverstar or Silverstar Ultra, PIAA, Hoen, Nokya, Polarg)
1500 lumens, 100/200 hours, 4000°K
1500 lumens, 100/200 hours, 5000°K
Higher wattage – 65 watts (no issues with the extra heat or load as it’s only 10 watts over stock)
Osram Rallye +65 (manufacturer part number: CP64217)
2100 lumens, x/500 hours, 3200°K
Lumens – this is the light output as measured by the manufacturer. This should not be used to measure the performance of a bulb as the filament design denotes the performance, the light output from many of the different types is around the same but the headlight performance and appearance of the bulbs differs vastly from long life to standard to high output.
- long life bulbs have larger filaments that burns cooler, this reduces the beam focus which shortens the throw of the light and creates a browner light colour.
- high output bulbs have smaller filaments that burn hotter, this tightens the beam focus which lengthens the throw of the light and creates a whiter light colour.
Hours – denoted as B3/TC. B3 is the average lifespan and TC is the point at which 63.2 percent of bulbs have failed.
Colour – measured in Kelvins. Further explination etc to follow.
- The figures may be a composite where there are multiple brands and types listed in a category, if one manufacturer differs greatly they will be listed separately and where figures are not available or are not accurate this will be noted by the manufacturers name being in italics.
