2013 Chevrolet Silverado 2500 HD Morimoto 2Stroke 3.0 LED High Beam Bulbs (SKU: LED1517)
Benchmark: Over the course of the last year, the Society of Automotive Engineers along with Tier 1 and Tier 2 suppliers have been carving out a new standard that defines what an industry-accepted LED headlight bulb would look like. While they have been hard at work creating whatÃs now known as SAE J3145: Morimoto was hard at work taking notes and more importantly; developing a product in parallel. While LED bulbs still arenÃt DOT approved for use in headlights in the statesÃ–. if and when the time comes, the new 2Stroke 3.0 is already built according to the right recipe. For now, foreign markets and fog light users can enjoy the best LED headlight bulb available today!
Superior Beam Quality: The advanced PCB technology at the core of the 2Stroke 3.0 sets a new industry benchmark emission surface interval of just 2.4mm total. The PCB core itself is just 1.0mm thick. The dielectric layer: 300um. The circuit pattern: 140um, and the Philips Lumileds Luxeon Z LED chips: just .59mm each. Paired with the tight light-emitting surface area of the LEDs: this adds up to a total cubic volume of 4.46mm. At the end of the day, no LED bulb in the world more closely simulates the filament size of an incandescent bulb more accurately than the Morimoto 2Stroke 3.0Ã–.and for those in the know, this is critical when it comes to proper beam distribution.
Integrated Micro-optic Reflector: The 2Stroke 3.0 H4 bulb has an innovative low beam shade cup with a built-in micro-optical reflector inside that enables their ability to illuminate reflector surfaces above the bulb. In a typical H4 application, only about 30% of the raw lumens are projected on the road as forward illumination. With this special optic, about 40% of the lumens will be projected onto the road. The region of the reflector directly above the bulb is responsible for a critical amount of light within the beam pattern, making this patent-pending feature a serious performance advantage over other H4 LED headlight bulbs.
Optimized focal length: Each size in the 2Stroke 3.0 lineup has been painstakingly optimized for proper output in its designated application. The critical reference distance has been calculated based on the geometry of the bulb base and the footprint of the Osram HKL emitter. To ensure consistency, special tools were designed to quality-control the accuracy of each bulb as it comes off the production line. Most other LED light bulbs on the market use a Ã¬set it and forget itÃ® reference distance across all sizes in the series, which is not the case here.
360 degrees of Rotation: The 2Stroke 3.0 LED bulbs feature a fully adjustable base. In order to fully utilize the optical facets in any reflector or projector: The light emitting diodes must face the 3-o-clock and 9-o-clock positions. Since no single standard exists across different headlight and fog light assemblies, all bulbs in the 2Stroke 3.0 range are fully adjustable. A geared step rotational adjuster mechanism is installed for all bulbs which twist-to-lock, offering adjustability in 15-degree intervals. An omni-adjustable rotation mechanism is utilized on all bulbs that are press-fit or clip into the housing.
Thermal management: Once the bulb is installed, the high-speed fan contained within is completely sealed, making the 2Stroke 3.0 the first actively cooled LED bulb with a fan thatÃs not susceptible to outside elements. Their unique internal circulation cooling system uses a 12,000-rpm cyclone fan to suck cool air into the body of the bulb and blow warm air out, back into the housing. On the intake side, cold air is sucked in past the sidewall of the PCB to exchange heat and is blown out the opposite side of the bulb. This effectively cools the bulb while warming the ambient temperature inside of the housing, increasing resistance to snow/ice buildup on the lens during the winter months. The cooling system on the 2Stroke 3.0 not only does itÃs job to protect the longevity of the bulb, but serves up a bad-weather benefit not found elsewhere.
LED Driver: The LED Driver on the 2Stroke 3.0 H4 Bulbs is made of die-cast AL thatÃs been electroplated. It has a double-lip seal, and has been completely potted. In combination with the high-quality over-molded wiring, these bulbs are all-weather ready.
