Is the luminous intensity of OSRAM LIGHT@DAY lamps as strong as that of standard lamps?
To tell you straight out: a longer lamp life will always be at the expense of the luminous intensity (for physical reasons). This fact applies to the LIGHT@DAY lamp range, too, of course. The required light values and the safety criteria are still always strictly adhered to! There is a simple rule: If you do a lot of daytime-driving, you will drive with your lights on during the day and use the LIGHT@DAY. If you do a lot of night-time driving, however, the perfect lamps for you to use are the high-performance lamps OSRAM SUPER 30% and SILVERSTAR 50%.
