100% agree with 1 and 2 as the best choices for the MDX!From the most powerful to ideal.
1.- OSRAM CBI
2.- MORIMOTO XB35
3.- OSRAM Nightbreaker
I did the OSRAM CBI cool blue intense Xenarc for my MDX in 2015 and RDX in 2016. The 2015 set came in at 5000K-5500K and the 2016 were up to 6000K. I notice the OEM 4300K-4500K leaned more yellow like early morning/late evening like a warm white light. I noticed the 5000k-5500K looks the brightest, longest range, widest beam width, and provide illumination the same as high noon is summer with zero clouds in the sky. The 5500k- 6000K will start to look more blue-ish as you look at it; but, will still look pure white on the road. Depending on the projectors, you will start to drop in illumination, range, and width as you go below 4300K or above 6000K.I did buy OSRAM Nightbreaker for $100 on Amazon and recently installed them. I'm pretty happy with them, because they are almost identical to OEM in terms of the colour temperature (4300-4700K), but they are noticeably brighter than OEM (which is understandable considering my OEM bulbs were 10 years old).
I didn't want to go with CBIs, because I completely despise the cool bluish tint (6000K, yikes!) for low beams in general and I would definitely not want them on my car, but that's just a matter of preference, of course. If I can get another 10 years from these bulbs just as I did from the OEM ones, that'd be great!
Sometimes it is hard to tell other times is easy. But, yes, I have received counterfeits from Amazon in many things. I have Amazon Prime, so I order regularly and give them a lot of my money. Early this year, I talked to a lady at a small Amazon shop in a mall in D.C. and the lady told me Amazon is aware the counterfeits issue is damaging their reputation. How much is Amazon doing to clean out from their stock and prevent it, it is uncertain.How can I be sure? I trust that Amazon isn't selling counterfeits. Is there a way to know when I receive them?
