Diode Dynamics SL2 Pro LED Headlight Kit (Pair)

Product Description

Aftermarket or OEM? If you’re looking to improve visibility on your vehicle at night, you’ve probably found many options for LED upgrades. Most bulbs on the market are too big to install, don’t work with the electrical system, and have no focus or hotspot in the beam pattern. Even if they come close on those aspects, they still aren’t anything close to the quality you would find with factory-installed lighting. Like most aftermarket products, most LED bulbs are not engineered and tested for long-term reliability.

 

Next-Generation TST Technology. The SL2 Pro features new thermal separation technology (TST) LEDs. Unlike a traditional LED chip, TST LEDs are designed with electrical connections on the top. This means the entire bottom surface of the LED can be dedicated to channeling thermal energy out and away from the LED. This lowers thermal resistance, allowing the SL2 Pro to run at higher power levels than traditional LED bulbs, while maintaining focus.

 

Optimized Optical Focus. Your vehicle’s housings are designed to focus light. If the light source in the housing is out of focus, it doesn’t matter how bright the bulb is – you won’t have a focused hotspot of light to shine down the road where you need it. Instead, you’ll have more glare, which lights up the foreground and makes it harder to see in the distance. The SL2 Pro LED bulb was engineered to focus light just like your original bulb, matching the original beam pattern while still providing an increase in total output. These days, some LED bulbs on the market use the smallest LEDs possible to accomplish focus, but this leads to “over-focus”, where you begin seeing streaks, lines, and harsh cutoffs in the beam pattern. Instead of using the smallest LEDs possible, the SL2 Pro was optimized to provide a smooth and comfortable beam pattern, while still maintaining focus and increased output.

 

Internal Cooling. The SL2 Pro features an integrated top-mounted fan for superior thermal management and reliability. Since the fan is sealed inside the housing, there’s no concerns about damage from dust or moisture over time. And with the fan on the top of the bulb, the cooling happens right next to the LEDs – the source of the heat. While standard LED bulbs use heat pipes and other tricks to move heat to the bottom of the bulb, where it’s cooled off, the SL2 Pro keeps it simple and more efficient. This provides maximum cooling efficiency and output.

 

Tested to Perform. We test the SL1 bulb in factory headlamps, and measure the entire beam pattern using specialized equipment. It’s an elaborate affair: a headlight is mounted to a computer-controlled rotating head called a goniometer. Light shines down a tunnel, where a sensor collects data as the headlight is rotated. The entire beam pattern is mapped, and we compare the total output to the original halogen, confirming that the SL1 bulb shines more light in the hotspot, without adding extra glare on the road. The test results speak for themselves: in most lamps, like the 2015 F-150 Halogen lamp, there is 30-70% more light in the critical hotspot, with no added glare or spread of light. With proper optical engineering, testing, and validation in the application, we can assure correct optical performance.

 

Fully Integrated Design. Unlike traditional LED bulbs, the SL2 Pro LED bulb doesn’t have any extra wires or external drivers. Along with its compact size, that means excellent fitment inside your housing, without the need to tuck away wiring or bulky drivers. Installation is easy – simply remove your factory bulbs and the SL2 Pro will fit in its place, with a plug-and-play connector. And if your original bulb is installed at an angle, no worries – SL2 Pro has you covered with an adjustable collar that can be securely locked at the correct position. For specific fitment information, please see Vehicle-Specific product listings, or contact us.

 

Reliability. Every part of the SL2 Pro LED was engineered for reliability, from its full metal construction to the fully-sealed design. The SL2 Pro was put through its paces in our environmental testing chambers – where the bulb lasted through repeated thermal cycles from -40 through 85 degrees Celsius (-40 to 185F), along with a range of other environmental tests. It’s also designed with transient protection, to prevent premature failure from electrical spikes in the vehicle. It’s even compatible up to 30V! We’re so confident in the SL2 Pro, that it’s backed by an industry-leading limited LIFETIME warranty. See details at diodedynamics.com/warranty.
