Engineered for Performance. Made in USA.
True Upgrade. Other LEDs on the market are too big, have no hotspot in the beam pattern, or they simply stop working after just a few months. The SL1 LED headlight bulb finally provides a true upgrade in performance, with its compact size, optically correct output, and high reliability. The Lumileds chips shine in a true white 5700K color temperature, without any hint of blue, for an OEM-style appearance.
Street Legal Output. Don't be fooled by high lumen numbers or "projector specific" bulbs. If the light source is out of focus, it doesn't matter how bright it is - you won't have a focused hotspot of light to shine down the road - just more glare.
To correct this, SL1 LED headlight bulbs were engineered with advanced optical design software, to perfectly match filament location. The SL1 LED shines light just like the original bulb, preserving the focus and hotspot, with no added glare. It produces a functional beam pattern on the road, in compliance with photometric standards, for a safe, functional output, which we call Street Legal.
Tested and Verified. To make sure everything works as intended, we use photometric test equipment to measure the entire beam pattern with the SL1 installed. A CNC rotating head called a goniometer holds a headlight, and the entire beam pattern is mapped. This way, we can confirm that SL1 LED headlight bulbs shine more light in the hotspot when installed, without adding extra glare on the road.
Just take a look at the "bird's eye view" test results. In most vehicles, there is 30-70% more light in focus, with no added glare. That means more light down the road.
Fitment. With its patent-pending design, the SL1 LED headlight bulb fits where other bulbs won't. It will fit under dust caps, and in tight spaces with no modification. There's no hanging metal straps. It's simply a compact bulb that plugs right in.
Reliability. From the high-temperature teflon wire, to the zinc castings, every part of the the SL1 was designed for reliability. The driver uses a unique boost-mode circuit, which prevents thermal imbalance in the LEDs, and has transient protection for long life in automotive circuits.
Finally, the SL1 bulb was put through its paces in our environmental testing chambers, through dozens of thermal cycles, from -40 to 150 degrees Celsius. The SL1 LED is a durable, reliable bulb, and is backed by a three year warranty.
