SL2 LED Headlight

Diode Dynamics set the standard for LED bulbs in 2017, with the introduction of the SL1 and SLF LED bulbs. After many years, and thanks to improvements in technology, we are excited to introduce their successors: the SL2 and SL2 Pro LED bulbs! The SL2 and SL2 Pro feature a number of upgrades, including a more compact design, internal driver, and improved reliability. These LED bulbs are direct plug-and-play replacements, providing a significant upgrade in performance.

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. The headlight housings on your Chevrolet Impala 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 and SL2 Pro LED bulbs were engineered to focus light just like your Impala's 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 and SL2 Pro LEDs were 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.

The SL2 was designed as a compact, fanless solution. But that doesn't mean it's low-power! At 14 watts, the SL2 LED bulb still provides plenty of output thanks to a copper-core circuit board and a thermally-optimized full-metal housing with integrated heatsink.

Fully Integrated Design. Unlike traditional LED bulbs, the SL2 and SL2 Pro LED bulbs don't have any extra wires or external drivers. Along with their compact size, that means excellent fitment inside your Impala's housing, without the need to tuck away wiring or bulky drivers. Installation is easy - simply remove your factory bulbs and these LED bulbs will fit in their 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.

Reliability. Every part of the SL2 and SL2 Pro LED was engineered for reliability, from its full metal construction to the fully-sealed design. The SL2 and SL2 Pro were put through their 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. They're also designed with transient protection, to prevent premature failure from electrical spikes in the vehicle. They're even compatible up to 30V! We're so confident in the SL2 and SL2 Pro LED bulbs, that they're backed by an industry-leading limited LIFETIME warranty. See details at diodedynamics.com/warranty.
