sha4000 Posted August 27, 2005 Share Posted August 27, 2005 i bought a new bulb for the passenger side last year but the old one on the drivers side is noticeably brighter than the new one i was wondering if the k is different and how do i check Quote Link to comment Share on other sites More sharing options...
ED. Posted August 27, 2005 Share Posted August 27, 2005 Do you have Xenons? If so I believe the K is 4300. Halogens should be 4000. I wonder if you have to replace Xenons in pairs? thanks Quote Link to comment Share on other sites More sharing options...
SW03ES Posted August 27, 2005 Share Posted August 27, 2005 All OEM HID is 4100k. Halogens are more like 3000k. The difference in the color is because of age. Like all headlights they should be replaced in pairs. Xenons get visably brighter and usually purpler as they age. Quote Link to comment Share on other sites More sharing options...

ED. Posted August 28, 2005 Share Posted August 28, 2005 I thought Lexus was 4300. I know BMW is. Quote Link to comment Share on other sites More sharing options...
bartkat Posted August 28, 2005 Share Posted August 28, 2005 Philips makes a replacement bulb that's about 4900 ct so it will match an old bulb and you don't have to replace both. Quote Link to comment Share on other sites More sharing options...

SW03ES Posted August 28, 2005 Share Posted August 28, 2005 ALL OEM HID is 4100k, its the only DOT legal color temperature. There wouldnt be any real difference between 4300k and 4100k anyway. Grand- No actually, older HIDs look brighter than new ones. bartkat's right about the Phillips bulb, I had forgotten about them. For the best match though I'd still replace both.

Don't know if he'll sell just one, but the price is ok. I got two because I wanted a slightly higher K without going too blue. http://cgi.ebay.com/ebaymotors/2-New-PHILI...995593359QQrdZ1 Quote Link to comment Share on other sites More sharing options...
SW03ES Posted August 28, 2005 Share Posted August 28, 2005 sha- But you already bought the new 4100k one, so you may as well just spend the money on another new 4100k bulb. Quote Link to comment Share on other sites More sharing options...

I lost some of the nice blueness for a while, but the new ones are definitely brighter. Quote Link to comment Share on other sites More sharing options...
SW03ES Posted August 28, 2005 Share Posted August 28, 2005 Think about it this way. As you move up the color temp scale the lights look bluer, but they put out less usable light. The optimum light output is OEM, 4100k. 6000 is dimmer, 8000even moreso. As the lights age they move up the color scale to 5000k or so, bluer but with less light output. That explains what you've experienced. Older bulbs are brighter colored, but put out less light. Make sense? Quote Link to comment Share on other sites More sharing options...

As the bulb ages, it gets LESS brighter, and more bluer. Because as the blub gets bluer, its gets dimmer as well. Quote Link to comment Share on other sites More sharing options...
SW03ES Posted August 28, 2005 Share Posted August 28, 2005 Thats the basic gist of it, but it doesn't really get dimmer in the sense that a halogen bulb gets dimmer. The nature of the light just changes. Quote Link to comment Share on other sites More sharing options...

This varies from bulb to another, some get bluer, some get purple (like acura's). Quote Link to comment Share on other sites More sharing options...

SW03ES Posted August 29, 2005 Share Posted August 29, 2005 Like everything else, its cheaper if you dont buy them at the dealer. You can find them for $100 or so online. GRAND- The blue/purple disparity is because of the housings the lights beam through. Soume housings (like projectors) bring out more purple while some (like reflectors) bring out the blue.

aahn Posted September 22, 2005 Share Posted September 22, 2005 hey there, looked into this actually because i recently wanted to get a HID conversion kit for my '00 RX to match the hue of my '03 SC, and the people I talked to said that Lexus uses Phillips bulbs and ballasts and are at 4300K. I actually bought a McCulloch 10000K kit... Quote Link to comment Share on other sites More sharing options...
SW03ES Posted September 22, 2005 Share Posted September 22, 2005 Just so you know, a 10,000k kit has approximately 50% the light output of a 4100k kit. The color is achieved by dying the glass. Quote Link to comment Share on other sites More sharing options...
