Argggggggh
The noise you make when you drop a brand new Osram Xenarc Nightbreaker Unlimited D3S bulb on a concrete garage floor and realise that mistake has just cost you 80 quid.
SWMBO said ahh butterfingers. I said off and leave me be.
Suggest you replace it with an Original Line instead - much cheaper and better vision and longer lasting. Current: Discovery 3 06MY (55 reg) HSE Auto Zambezi Silver Allisport Fast Road Intercooler, V8 Brakes, Silicone IC Hoses, EGRs Blanked, Remapped, De-Cat pipe, FBHIC

Sorry but I don't agree (other than perhaps on the longevity point). You link takes me to the standard fitment bulbs I've just taken out. Having used them before in previous D4 and from experience driving last night (having replaced the one I dropped with one from local motor factor), the Nightbreaker Unlimited D3S bulbs are much better than the ones you linked to.
Problem is in a D4 facelift is that there are no main beam fill in lights like there are on D3/earlier D4. The standard HIDs are pants in comparison.
The Nightbreakers are not brighter - under the regulations they are not allowed to be. They instead are a higher colour temperature, which is worse for the human eye. It can make you think they are brighter, but they aren't.

The old bulbs will have been tired so you will always see a big improvement when fitting new bulbs.

The old bulbs weren't tired they have only done 8k miles........
Those data sheets don't make a comparison as far as I can see. Whilst the D3S bulb (66340) is shown on the 'original' sheet it isn't shown on the 'Nightbreaker Unlimited' sheet (66340XNB).
So you are comparing output of D3S original with D1S and D2S nightbreaker unlimited, both of which are older and inferior bulb designs to D3S.
I shall take it that doesn't equate to many hours.
Well, the figures are there, and the science behind colour temperature has been well studied. The increase in colour temperature is extremely deceptive and that's how the con works. We cannot accurately determine the brightness with our eyes, so these factors play straight into the manufacturers hands.

No, I'm not comparing them in that way - I had previously uploaded those sheets before as a comparison between the others. The same applies though. 3200lm is the limit for D1S, D2S, D3S and D4S bulbs and you will find the same figure on the Osram site.

Have you actually compared the physical results side by side?

Quick question, are these bulbs only for a D4 or do they fit a standard D3 with Xenons?

D2S for D3 xenons.

The human eye is not physically capable of doing so accurately. That's the crux of the whole thing, (excuse the pun) you see.
It's counter intuitive, but the science is backed up by simple logic, and can be seen in action when you compare typical glare from different coloured lights and look at how the perceived colour changes in differet ambient light conditions, so I am happy to go with it and save my money.
OK, I'm a bit geeky about it, but if it gets me better or equal vision and saves me money then it's worthwhile. Current: Discovery 3 06MY (55 reg) HSE Auto Zambezi Silver Allisport Fast Road Intercooler, V8 Brakes, Silicone IC Hoses, EGRs Blanked, Remapped, De-Cat pipe, FBHIC

Each to their own
All I can say is I've driven the same road, in the same car, in the same conditions, 24 hours apart firstly with the standard Osram D3S and secondly with the Nightbreaker Unlimited D3S, only 6 months difference in the age of the bulbs.
I am categorically of the view that I can see better and further (note I don't say brighter) with the upgrade bulbs. Regardless of what the technical blurb says, for me that is the end of the story.
I don't blame you because I'm the last person to blindly believe the "technical blurb" stuff, but bear in mind, the other side is just blurb from Osram.

There's more to light than just brightness. Sometimes the frequency and colour temperature of the light can change your ability to focus - i.e.. the shorter the wave length the easier it is to focus on detail. The beam pattern changed by small changes to the bulb could also alter your perception of overall brightness. A wide soft light can be just as bright (in LUX) as a hard spot light... but your brain doesn't see it that way!
I have no view on either of these bulbs but I do know it's very difficult to accurately measure the perceived brightness of something... I try to most days!2005 D3 HSE 2011 D4 Landmark 2016 D4 HSE Lux
