    I don't think you'd need to change anything, but if you could mount the headlight on some rubber isolators to dampen it from engine/suspension vibrations it may extend the life as the filament wears thinner and weaker.

      Ryan (or anyone),

      Where would you find a philips 9011 right now? All I can find in philips is their standard 3k bulb. Thanks

          rdriggett,

          What H4 would you recommend with at least 450h lifespan? Philips Xtreme 130? Or there is any better one?

          I'd like the RacingVision, but 250h is too short for me.

          Thank and Congrats for the topic.

            Sorry for the late reply, I only occasionally check this now. Philips xv +130 would be in that ballpark depending on your specifics.

              "The Flösser and Osram bulbs are electrically, optically, functionally, and qualitatively identical, but they are labelled differently. They are both built in Germany to exactly the same specification: an H9 burner on an H7 base, 65w at 12.0v, 2100 lumens at 13.2v. Flösser's box says "80w" while Osram's says "65w". This is not[FONT=verdana] an actual power difference, it is a test voltage difference. Flösser power-rates their bulb at 13.5v rather than 12.0v. For any/all filament bulbs, the wattage rises exponentially to the power 1.6 with voltage increase. So a bulb rated 65w at 12.0v will be rated 78.5w (printed as 80w) at 13.5v. It's not two different bulbs, just two different test protocols. On the test bench, the Osram "65w" bulbs and the Flösser "80w" bulbs all test out at between 63.8 and 65.4 watts at a constant 13.2 volts.[j/FONT]"
              My apologies for resurrecting this thread. It seems that Flosser still has these 80w bulbs in their 2020 catalogue and I do find them for sale. However this is the only place where I find that they are in fact the same as the old discontinued Osram Rallye 65w so I'm a bit concerned with running these 80w bulbs. Can you still confirm that this is really 65w and that they should work just the same as the Osrams with no overheating issues?

              (search for 12070 in the pdf to find it)

              Thank you!
