    Do any of these diffraction coated or yellow tinted bulbs still fall identifiably within what is federally defined as "white light" for the headlamps? This is an issue I have run into with various bulbs, that local law enforcements means of testing for "whiteness" was to hold up a sheet of white paper (or printed tyvek ticket) in the illuminated beam and say "yep, thats yellow, not white."

    Those Lunex I mentioned earlier are pretty mild and would likely hit the white chromaticity windows requirements, though I did not validate that with measured chromaticity data. The pictures of the color in the app are not great, but you can see they have a slight golden hue but don't jump out as being a significantly altered halogen color. For temp I had them at just over 3000k. I didn't have the ability to measure and plot chromaticity before when I tested them, but I do now. Bulbs that advertise 2500k or have yellow coatings will be far to yellow for the required 'white light' for headlights. A white sheet of paper is obviously a pretty poor technical assessment, but if it stands out and looks the part to the point where an officer is performing that 'test' on the vehicle, your likely going to get cited for it regardless.

    How would you compare SL1 from Diode Dynamics vs the Hikari Ultras?

    You can see the reviews of each below.

    Diode Dynamics SL1 LED Headlight
    Original review posted here.

    Hikari Ultra "Eyes of Megatron" H11/H9 LEDs
    See the original review in post #1608 here.

    The Hikaris have better focus and much higher intensity output. They are the only replacement LED I have tested that outperform stock in the 3rd Gen projector. While optical performance and design is good, the build quality for the long haul seems questionable. Here is a 42’ distance test intensity comparison between the SL1 and the Hikari Ultra.

    Without modifying the bulb connector, yes. The GE Xenon H11s are slightly higher in output intensity, but do cost more.

    Can’t speak for anyone else, but for $14 or so for a pair and about thirty seconds with a Dremel the Phillips H9 are my choice. Just hopeful it will last for a year or so.

    Why? Why test it? It’s still a overly thick LED emitter, thicker than the Hikari and Diode Dynamics already tested, in reflector housing (for the high beams) so it’s still not going to work as well as a halogen bulb, particularly not as good as the factory Phillips H9 bulb you took out to replace it. You can see yourself that it doesn’t work well...

    As @skierd pointed out, the design is poor. The distance between emitters is too far off center with the thick blade design. Having 2 rows of emitters rather than one is going to make it too large to replicate a halogen filament and also so that neither row of emitters is centered correctly which is going to further cause poor focus, which means its distance projection will be poor. Really not much point in testing it.

    Thank you! I didn't really know which thread would be most appropriate to pose that question but assumed this would be best as it is focusing on the H11/H9 bulbs. I didn't want to PM you because some may be looking for similar info but don't want to ask or don't know how to ask the question.

    I have seen the Xencn bulbs in my searches but also thought the same thing about questionable quality. I was not aware that Nokya made an H9 in the Hyper Yellow. I have Moroimoto EVO-XR projectors with 5500k bulbs in the headlights and wanted a nice looking contrast since the headlights are plenty bright plus the added benefits of poor weather condition visibility. I'll likely try the Nokya bulbs to see how I like them and order a set of Philips H9's at the same time since I have seen questionable reliability on Nokya bulbs. However I often attribute that to the installer touching the bulb and not cleaning it or something like that.

    I've got a set of Hyper Yellows i've had on for over a year and they are great. Not super bright since they are yellow but do project super well, good wide field of view, and can't be beat if driving in inclement weather with poor visibility.

    I've had the hyper yellow H9's in for about 5 months. Not as bright as the Philips H9, but definitely better than stock.

    I understand that they will not be as bright as an uncoated bulb. But I wonder if the color helps see better in poor weather than just having a brighter uncoated bulb. That's the million dollar question. However being that it is on a car that is considerably lower than our trucks is if it will be a noticeable difference. I guess the only way is to try it as it is somewhat subjective.

    So, a yellow tinted halogen bulb, or a slip-on bulb filter over a clear bulb, or tinting the lens of your headlight and running a clear bulb are all going to result in somewhat diminished output. Daniel Sterns site has an excellent breakdown on "Selective Yellow," which is what I was aiming for when I first tinted the lenses of my 4runner (see pic attached). With one headlight tinted and the other not, you can see the difference if you really look for it. Otherwise, meh, not really.

    You will see a big difference if you frequently drive in heavy fog and/or rain. It cuts a hugely noticable portion of the backscatter out of the road in front of you. Its not perfect, you still see the fog, but drive up next to someone who has normal halogens or a high color temp HID or LED bulb in the same conditions, and you can see lightyears better than them.

    Also has the really nice effect of mellowing out signage that uses a white or blue metallic based reflective paint. Still lights it up, but now its all illuminated, not glaring back at you.

    After I got popped one too many times for tinted lenses (not legal in PA), I bought a set of selective yellow slip-on bulb covers from rallylights.com/susquehanna motorsports. The shape of them works well for the low beam on an H4/9003 bulb, but the curvature of them sits right iver the high beam filament, so it works great for the 80% of driving on low beam only, but it did make a noticeable negative difference on high beam. I dont have a vehicle that uses a H11/H9 to tell you if the same covers would work for them, but they're only like $7/set, so you could give them a try over a high output/high quality bulb like an H9 and see if you like them.

    That would be interesting to test the difference between the cover for the bulb and the tinted bulb itself. I don't have any of the testing equipment but it would be cool! I have some film from Vivvid that I plan on putting on my beater subaru fog lights since one lens has a small hole in the lens and I figure the film will seal it too.

    I don't mean to get people off topic, but I was curious and I figured this would be the best place since my use is the H11/H9 and is in a projector.

    Sooo looking at post #2 on this thread, A $6.93 H9 bulb is king of Halogens using a stock headlight performance wise? Does this still stand as of today? Also, using Lux chart @ 18' is there any difference in real world driving between 1k+ lux group. Obviously numbers are numbers but speaking as yes this bulb @ 12xx is much brighter than this 1xxx
