Clear Vision Supreme vs SilverStar Ultra

We compared Eiko's Clear Vision Supreme with SoLux Technology and Sylvania's SilverStar Ultra in the same vehicle traveling the same country road. What we found is Clear Vision provided better visual acuity, a wider field of view. We also discovered from Sylvania's own packaging that SilverStar lasts only 1/4th as long and we also measured a 15% decrease in output after only 2 weeks of service with visible signs of degradation.
