Good evening all I am looking at changing the bulbs I have a set of orsam night breaker extrem but I think they look a bit blue like a cheep chav hid kit so am looking for some pure white ones is there any that you guys recommend and photos of them cheers

Cool Blue Intense won't offer the truest colour; the claim is made on the fact that bright daylight is at approx 6000k, but that's not all there is too it - the spectrum offered by a 6000k bulb will be poorer and our eyes function differently under lower light conditions. They output fewer lumens also and are more glaring for other road users.

I would always stick with 4300k since it offers the greatest lumenous efficacy for HID bulbs, best colour rendering and no blue tint - I suggest Osram Original Line. See below.

Well, most of the "upgrade" ones are 5000k, or 6000k, which means less light (and more glare for other road users). Most of them command a premium price (or are cheap Ebay rubbish) which doesn't get you better performance, so I would (and did) choose to save my money. As with all bulbs, to be E-marked, they have to stay within a certain range anyway.

For example, Osram's own technical data:

Xenarc Nightbreaker D2S

Lumenous flux: 3200lm (+/- 15%)
Lifespan B3: 1500h
Lifespan Tc: 2500h

Xenarc Original D2S

Lumenous flux: 3200lm (+/- 15%)
Lifespan B3: 2000h
Lifespan Tc: 3000h

Quote:

Nightbreaker Unlimited H7

Lumenous flux: 1500lm (+/- 10%)
Lifespan B3: 150h
Lifespan Tc: 250h

Original Line H7

Lumenous flux: 1500lm (+/- 10%)
Lifespan B3: 330h
Lifespan Tc: 550h

It's a clever trick they (not just Osram, they all do it) play to get away with what is actually a big sham.  Visiting from DISCO3.CO.UK

All do respect...you are wrong.

Sunlight is rated at ~5000k. CBI are NOT 6000k bulbs. I've been to this rodeo a million times....did many Projector retrofits also. Osram CBI are the best bulbs you can buy at the moment. They are the best color and brightness. End of story.

OP refer to my previous post and get the Osram CBI. Get the from a reputable source such as TheRetrofitSource....there are a lot of Chinamen making fakes.

Fine...be like that. OK, I admit I made a mistake and the CBIs are 5500K, but rest still stands.

Here are Osram's figures:

Have you ever used them? Or are you going by what you can google? CBI are not going to be blue. It will be the purest white. The Ultinons may be getting in your head as far as blue and lack of lumens...which they are. I have a set of CBI on my Range and my M5. I've compared all models of Philips and Osram D1S first hand as well. CBI passed the eye yest and photo test being the brightest and whitest.

Go to HIDplanet forums and see where they compare and meter the bulbs. 2014 FF Autobiography 5.0 SC

No, I have not used them. That makes no difference, because the human eye is useless at distinguishing outright brightness. The human eye can, however, distinguish very small changes in colour temperature, so this distorts our perception, however the appearence of the colour is also subjective (this explains why quite well: http://www.solux.net/cgi-bin/tlistore/info...ponse.html).

Now, outside of this, a light appearing whiter is not what colour rendering is about. White light is just a combination of the wavelengths. If you add a bit of red, green and blue together you will get white, if you add red, orange, yellow, green, blue, indigo and violet you will also get white. This is, in basic terms what colour rendering is. Differen't light sources can appear the same but output different spectrums. An incandescent lamp produces a perfectly smooth coverage across the spectrum, whereas HID and LED, though having a far higher luminous efficacy, emit their light in a "spikey" spectrum; that is to say, they emit highly at certain precise wavelengths but they leave "gaps".

It's pretty common knowledge that 4300K is the most efficient colour temperature for such HID lighting (LEDs typically reach peak efficacy at 6000K, for instance) and Osrams data confirms this. HID bulbs at higher colour temperatures may be/appear whiter, however they are more lacking in the longer light wavelengths. The human eye, and indeed the brain, doesn't respond to all light wavelengths in a uniform manner. We actually don't handle shorter wavelength, blue light as well as we do longer wavelength, yellow, making it more glaring. Warmer light favours photopic vision and encourages our pupils to constrict preventing the glare seem from bluer light.

As I say, Orams figures show 3200lm for all their projector bulbs, as is the maximum allowed under ECE regulations.
