SL1 LED Headlight for Subaru Forester



Diode Dynamics is pleased to offer the USA-made SL1 LED headlight for Subaru Forester applications.

SL1 LED Headlight. If you're looking to improve your visibility at night, you've probably seen many options available for LED upgrades. There's plenty of LED bulbs on the market, but they all have their shortcomings. They're too big to install, have no hotspot in the beam pattern, or they simply stop working after just a few months. With its compact size, optically correct output, thermally-modeled cooling, and boost-mode electrical circuit, the Diode Dynamics' SL1 LED finally provides a true upgrade in performance.


Street Legal Output. Don't be fooled by high lumen numbers or "projector specific" bulbs. Your car's headlights are designed to focus light. 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, the Diode Dynamics' SL1 LED headlight bulb was engineered with advanced optical design software, to perfectly match filament location. This allows the SL1 LED to focus light just like an 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 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 below, there is 30-70% more light in the critical hotspot, with no added glare or spread of light. With optical engineering, testing, and validation in the application, we can assure correct optical performance.





Staying Cool. You may have seen bulbs that use large straps for cooling, or fans that just make noise. These bulbs run hot, resulting in degradation of output after a few months. When it comes to cooling, proper engineering is required to efficiently remove heat from the bulb. In the SL1, a copper core board, thermal phase-change material, and thermally-modeled zinc casting get heat to the base, where base fins release it, designed for aerodynamic performance in conjunction with the flow rate and pressure of the Sunon bearingless microfan. The result is a highly-effective and reliable cooling system, keeping the bulb running at maximum potential.


Fitment. With its patent-pending design, the SL1 LED fits where other bulbs won't, without cutting or modification. There's no hanging metal straps, just a compact bulb that plugs right in, with a nylon-reinforced shroud. Only slightly larger than a standard halogen bulb, it fits behind dust caps and in tight spaces. The base sizes are keyed for exact applications, not one-size-fits-all, and the compact driver easily tucks away.


Reliability. Every part of the SL1 LED was designed for reliability, from the high-temperature teflon wire, to the zinc castings, to the reinforced plastics. The compact 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 - where the bulb successfully performed through dozens of thermal cycles, from -40 through 150 degrees Celsius. The SL1 will keep performing for years, and is backed by a three year warranty.


Experience. After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting. Unlike every other LED distributor, we manufacture and engineer products ourselves in the United States, for high quality and fast time-to-market of the newest and brightest LED technologies. We pride ourselves in offering only quality LED products, that will exceed your expectations.

Will you have a matching high beam that can run in DRL mode (at DRL brightness, not at full brightness)?
The SL1 high-beams will run at full brightness or be off, depending on how your Forester is setup. Thanks!

How might one make that determination? The only thing holding me back is this drl brightness question. I don’t want mismatched headlights (stock highs and DD Lows) no do I want my high beams on all the time as DRLs

Thanks

Let me correct myself, there's a modification a member on the forum has posted about to shut off the high-beam as the DRL, but otherwise the SL1 will run at full power for the high-beam location.

Does that mean the high beam SL1 operates fine at 6V? That seems to be the voltage supplied to the halogen bulbs when in DRL mode.

The SL1 utilizes a boost driver circuit, which allows it to operate at full brightness down to 4V.

Thanks!

Has anyone reported an issue (ie complaint from LE or oncoming traffic) with the SL1 highbeam on as a DRL during the daytime....???

thanx Ken.
The SL1's output pattern matches the OEM Halogen bulb's output pattern. It's unlikely you'll be flashed.

They have a very-OEM like appearance as well, with the 5,700K color temperature.

Thank you!

You will need to disconnect the DRL resistor if using the SL1's as the high beam bulb. They will not be dim like the normal filament bulbs as they are rated down to 4v, IIRC.

Which means, if you want the DRL effect you'll have to drive with your driving/parking lamps on... Or wire up your fog lights to run separately....

thanx, frankly I would like to wire up my parking lamps as the DRLs, but will try the high beam SL1s first...

Given that the SL1's have a boost circuit, it's a shame they don't detect a low input voltage, say 4V to 9V, and automatically run at half power DRL mode. Plug and Play.

Forum member submitted output shot with the SL1s installed on his 2016!

Note: the slight amount of output above the cutoff mimics the OEM pattern nicely!​

If ya did it make my lighting decision so simple not even my wife could argue against it!!

An alternitive solution I would accept is a relay or a magic box that prevents a low voltage input from lighting the led. Thus deleting the drl function... not ideal but acceptable.

But for real please make an led bulb replacement for use in low voltage high/low beam DRL application. I’d be your first customer. Also I can’t find a single reputable mfg of such a product, so it seems you’d be first to market too!!!!
