I don't know exactly, it should be stated in the description. I'm very happy with this lamp, the light is bright and the lifespan is certainly good. So far, so good

I bought these in November 2023 and now one of them has broken. I don't think it's possible to say how long the service life is, as the external conditions have a big influence. But what I can say is that the light from the Philips RacingVision is excellent!
