HID light output vs color render, HELP PLEASE

[jet-6]

Guys im about to upgrade all my lights to HID, got a great offer i cant miss out on, BUT i have the choise of 4300k or 6000k, now i know the basics, 4300 will be brighter but not as white and vise versa, BUT does anyone have some NON adjusted pics of the two used in a test

Im almost sold on the 4300 since my crysal visions in my fogs are 4300k, but i have seen a set of BAXTER 7" spots and im told there 6000k and there damn good

I have XGT's to do and my stock GU headlights, i have been offered both kits for less than $300 and that includes the H4's as bi-xenon's

4300k
I've had both

4300k are nice
6000k are too blue

This is what im thinking, did you happen to get any pics of the two?

[Big Red Toy]

nah, heaps on the net thou
Google is your friend, just type in HID

The higher the Kelvin the bluer the light is then it'll go into the violet spectrum.

In the colour spectrum the colour blue will give you the furtherest amount of light, if it went to violet it'd go even further but the colour tint might be too much for some people.

Blue and violet are the last colours to be filtered out that's why the Sky is blue, it also goes the deepest into water same reason for water looking blue when scuber diving.

I hope that will help you.

All of the above is true. Also depends on the brand however as I've seen some big differences between HID's supposedly at the same colour temp.

4300k are nice
6000k are too blue

Personal preference makes a huge difference. I am partially colorblind and i find the 6500k really nice. For me anything under 5000k seems yellow. 6000k would be my preference.
Unfortunately photos don't do a great deal of justice to the light output, you need to sit behind them.

Yer after looking at a set of Baxters at 6000 im pretty happy with that, ill keep looking till Monday and order what i decide on the day

I have some 48 watt HID's in my XGT's. They are 4600k. With the clear covers on the XGT's they make a fantastic white light. With the blue covers on the XGT's which probably changes the colour temp to around 6000k i find it too blue. I much prefer the whiter light.

Coupla pics that Ive taken over the past two years...


Coupla differences in Lightforce's (ISO 400)


Coupla differences in Lightforce's (ISO 100)






45w 5000k vs 42w 6000k






The box said 6000k. But had to have been a 5000k


Best I've seen so far are the 55w 5000k kit in a pair of XGT's.
Those two (mounted on the roof) on their own completely blew away the four Blitz's that I had mounted on the bull bar with 35w 6000k in each.

Apparently 12v 75w HID kits (H1, H3 bulb type etc) are available now, but I personally have not seen any advertised.

I find I have more trouble seeing properly with the "brighter", bluer lights. Maybe it's just my eyes, but others I've spoken to have found the same thing.

Others swear by the bluer ones, but always difficult to know if it's not them trying to rationalise the $$$ spent???

Fair Point actually, i guess all our eyes are different

The 4600k i had were in My standard headlight & were nice, the 45w kit i have look very blue, but might work for you

Cheers for all the info guys, im almost convinced to run with the 6000 and allow that there a shi tter quality globe, lol

Blue and violet are the last colours to be filtered out that's why the Sky is blue, it also goes the deepest into water same reason for water looking blue when scuber diving.

Um, sort of. The sky is blue because shorter wavelengths (blue, violet) are scattered by air molecules about 9 times more than longer wavelengths. Water has an intrinsic colour, and the reason is alot more complicated than it taking the colour of the sky or 'blue light traveling further', which is rubbish. Our eyes have a greater response in the blue part of the spectrum, which may explain the phenomenon of it 'travelling further', perhaps you are just seeing the very weak light reflected back from long distance in the case of a light in a 4x4.

I'm a lighting technician, I'm not pulling this out of my arse, lol.

This is much better. I think the first explaination had it's merrits but wasn't explianed in technical terms.
I have color discrepencies at the ends of the spectrum. Therefore my reds and oranges and blues and violets are not filtered through the lens of my eyes correctly.

I ordered 6000's, i could not decide, so i just wrote the two down on paper, shut my eyes and pointed! 6000 won
