I plan on upgrading my low beams but wasn't sure if there are any other aftermarket offerings that function bright and last long besides the usual Philip's and Osrams. I saw Morimoto bulbs are not bad for the price but they are also not as bright as Philip's. Just wanted to see what else is there and what you guys are using while of course saving some money if possible. I prefer 4300K through 5500K (nothing at 6000K+) for the warm or purest whites while maintaining good light output.

 

Check out Diode Dynamics. I have their HID low beam and fog light replacements and am very happy with the results. They are a vendor on here as well.

 

Osram CBIs have stronger outputs compared to OEM in my experience. I recommend them.

 

I forgot to mention I prefer 5000K over 4300K. they currently only have 4300K but I was wondering how much brighter is theirs compared to the OEM? My wife's plug n play kit I installed on her Mazda 6 is retarded bright compared to the OEM on the IS-F.

 

I wasn't too fond of the CBI because they put out that white/bluish LED look which I'm not fond of. I prefer the purest white at 5000K or at least a warm white like 4300K. Philips, Osram and a few others advertise there's in weird spectrums like 4800K and 5500K but to each of their own, if it's a nice pure or warm white that's brighter than OEM, then I'm interested. I'm not a fan of 6000K+ because to me it gives you that false brightness like how everyone assumes LED is always brighter when that's not entirely true. Plus it gives off that weird white/bluish hue like the OEM LEDs on the '19 ES350 that I drive around as a loaner. They weren't even bright either.

 

I got OEM from Amazon, whatever the OEM color was (4300k?)...worked great.

I’m sure color is subjective. But here you see these are “rated” at 4300. Might be what you might want.

 

They have 3000k to 8000k, including 5000k. I think I went with 5000k (also to match the fogs). Anything higher is whiter/bluer but not necessarily "brighter" The higher you go in the Kelvin Rating, you get more color in the light in exchange for visibility.

EDIT: I see what you mean now. They offer them but are out of stock currently. Another source I have used for a different car is Xenon Depot, which offers Osram and Phillips.

I run the Osram CBIs and (after 30 second warm up) although they are marketed as 5K, they do not show a hint of blue to my eyes. The Osram CBBs are marketed as 6K, but were tested to put out more light (420 lux) and run about the same color as the CBIs

Here is a good comparison -

 

That's pretty odd how Osram rated their bulbs. It doesn't seem to go along the usual identification based on Kelvin. Interesting though. Also, don't forget they are using Morimoto projectors. I've seen a pretty difference HID kits rated the same Kelvin, put into different projectors on different cars, some came out between warm white, pure white and bluish white due to the different projectors being used. I remember for awhile the S2K, TSX and TL projectors were the high end when it came to retrofitting nice headlights.

 

Im using these as well

 

Reviving from the dead but I cannot seem to find their vendor page on CL.

 

Fit perfectly on my 08 IS F

I saw this one but they are mainly for the fog lamps. I'll PM them anyways.
