However, the projectors in the FR-S are quite good. The main problem with HID is when it is installed into reflector housings, and the factory optic cannot direct this extra light properly. However, you do add quite a bit of light everywhere as well, including some on the top end. With HID, you get a focused beam, and a lot of light, so there is indeed a significant improvement in visibility. Just for comparison, we included a standard HID output. As you can see, if you use an LED bulb for your headlights, you'll get some light output, but it will not shine very far down the road because it is not being focused into a hotspot at the proper location. It doesn't matter how much light you have if it isn't going in the right direction. But since it is not being focused where it should be, the end result is that your visibility will decrease. In reality, the total output is usually about the same as halogen, and sometimes it's a bit higher. Many sellers claim high lumen numbers, telling you the output is higher than halogen. You want all of the light focused right in the center, with a small area to the sides also illuminated, and just a bit below. This is key to performance and visibility. As you can see, the factory halogen light is focused into a very tight beam, with a hotspot right at the center, which shines light far down the road. Sure, you don't want light sprayed everywhere, but more importantly, you need light focused properly. Many companies justify that the output of their LEDs is OK, just because there is a cutoff line. The real pictures below tell a very different story.Ĭutoff doesn't matter. Most companies selling these products for low beam application show very poor comparison pictures, where they are washed out so you can't actually see the beam pattern. Just thought some of you may appreciate this comparison! I just took these shots for a customer, to show them why the LED bulbs on the market are still not a good option, even when using a halogen projector, like that found on the Mazda 6. We constantly have customers ask about using LED bulbs in low-beam headlight applications, like the FR-S.
