In 2017, Diode Dynamics reinvented the LED bulb market with the SL1, the first bulb to provide a true increase in performance. Along with the SLF, these bulbs quickly set the standard for bulb performance, and are popular to this day. With advances in technology since then, it’s time to define a new standard. We are excited to announce the all-new Diode Dynamics H11/H8/H9 White SL2 Pro LED Bulb (Single).
Diode Dynamics H11/H8/H9 White SL2 Pro LED Bulb (Single) Features:
- Direct plug-and-play replacement bulb.
- Fully integrated design no extra drivers or wires.
- Advanced TST LED Technology for industry-leading performance.
- Internal cooling for superior reliability.
- Full metal construction copper circuit board.
- Designed and engineered in USA.
SL2 Pro LED Bulb Overview. The SL2 Pro from Nomadic Supply Company replaces our popular SL1 LED Bulb with a number of upgrades including next-generation TST LED technology an integrated top-mounting fan and an internal driver. The all-new SL2 Pro LED bulb is a direct plug-and-play replacement and provides a significant upgrade in performance compared to OEM halogen bulbs.
Next-Generation TST Technology. The SL2 Pro uses thermal separation technology (TST) which reduces thermal resistance and allows the SL2 Pro to run at a higher temperature. Unlike a traditional LED chip TST Technology separates the electrical connections on the top side from the thermal pad on the bottom side. This increases the surface area that can be used to dissipate heat meaning the SL2 Pro can run at a higher power for a longer amount of time.
Correct Optical Focus. The SL2 Pro LED bulb was engineered to focus light just like your original bulb preserving the focus and hotspot with no added glare. It produces a functional pattern on the road with a stronger hotspot for added distance.
Internal Cooling. The SL2 Pro features an integrated top-mounted fan for superior thermal management. With the fan on the top of the bulb the heat generated by the LEDs circulates into the lamp to spread warm air. While it might not melt snow it certainly helps.
NOTE: LED bulbs are legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. International legality varies by country.
