SL1 H8 LED Bulbs: Diode Dynamics came to the market with these SL1 H8 LED Bulbs and we couldn't be much more impressed. They rightly call attention to the exceptionally high build quality and reliability of these lights as well as their smartly designed hotspot and clear optics. Take a deeper dive into what makes the SL1 Special below.
Optimized Performance: We all want performance without compromise and the SL1 delivers that. Unlike other bulbs that claim insane lumen numbers, or aren't legal on the road, the SL1 Fog Light backs up its claims with clear evidence of their ability to produce brighter light (1630 lumens) in a clear and well-defined beam pattern that reduces glare and wasted light. They can manage that thanks to their in-house advanced optical design software which uses a process called 'ray tracing' to simulate exactly what each ray of light is doing as it leaves the light source and works its way onto the target. Through this process, they've ensured that every ray possible brightens up your path.
Rugged Design: While brightness is key in any good light, Diode Dynamics took exception to all the cheap junk out there that starts out bright but can't stand up to the workload of OEM lights. The SL1 was built from the ground up to meet or exceed the reliability standards of OEM lighting. It's been torture-tested from temperatures ranging from -40 to 185 degrees F. Combine that with stress relief points in the wiring harness, solderless terminals, and exclusive zinc castings and you can see why we like it so much.
Size and Heat: A major issue with the vast majority of LED lights on the market today is heat evacuation. To combat high temperatures, many manufacturers incorporate large fans or heat sinks into the bulb assembly. More often than not, these aren't even adequate enough to ensure a long life. At the same time, those large parts ensure that fitment is a pain thanks to the additional heft. Diode Dynamics works around this problem with intelligent engineering in the form of a MagLev fan that won't create interference as it cools the bulb. Because of this high-end tech, the bulb isn't much larger than the original halogen unit, allowing for easier installation and use.
Boost Mode Circuitry: In keeping with their OEM or better quality control, Diode Dynamics uses the same Boost Most Circuitry that you'd find in an OEM LED bulb to ensure that no electrical system can cause an uneven load on the LEDs and burn them out. It's even capable of handling many complex systems that would otherwise require an additional Canbus harness.

Camry 2010 H11 Diode LEDs
Very nice indeed. Essentially the same pattern at the halogens, with a nice bright white light of course. Easy to install, the cooling fans are not noticeable when driving the car. And the product looks to be of high quality. So overall for this particular projector headlight application i would highly recommend this bulb.
Brighter than stock
Just bought these for my Mazda 6 in hopes to replace my GTRlighting gen 3 bulbs. It was definitely brighter than the stock halogens, however the beam pattern was not that good on these hand lamps. Looking at the beam pattern projected on the ground, the GTRLighting bulb and the stock halogen has a fuller beam. The DD SL1 has a noticeable shadow the the middle of the beam . I doubt that i installed it wrong since the bulb can only go in one way.
Diode Dynamics is Legit!!
I originally bought some $30 Amazon LED's based on reviews. While it was an improvement over original Halogen bulbs the difference was minimal as far as better lighting goes. Not fully satisfied with the Amazon LED's I was looking at the Diode Dynamic and another brand of similar price. I went with Diode Dynamic for reviews on support alone. The quality is on point and made a huge difference compared to the Amazon LED's. I would definitely buy this product again. Install is pretty straight forward. I had a little trouble trying to install one bulb but that was because of the limited space I had to work with to get bulb into housing. Stay away from ones that offer lifetime warranty, there is a reason behind all that!
I waited forever for these to come into stock and paid $300 for headlights and fog lights. I just tried to install them and the 3 tabs that hold these in all broke. They are made of paper thin plastic! Original halogens have metal tabs. DO NOT WASTE YOUR MONEY!
I paid $300 for these bulbs and a set for my fog lights. The 3 tabs to hold the bulb in the socket broke. They are made of paper thin plastic!!! The halogens are made of metal. CHEAP GARBAGE! DO NOT BUY!
Definitely brighter and whiter than stock. Easy to install. I may have to try the yellow ones next.
2014 chevy silverado ltz projectors
This is the third set of leds i bought. Ihave bought morimoto, and gtr gen3 they didnt fit. The diode dynamics SL1 h11 fit perfect but the 9005 didnt not fit the highbeams. They have a nice output BUT real world the hotspot is still slightly brighter than halogen but the side output is much brighter. Combined with the morimoto xb foglights i have great visibility.
Not great for WRX
These lights are bright and easy to install but not a good beam pattern for the 2017 Subaru WRX projector. It creates two bright vertical lines in the lense but no output in the 12 or 6 o clock position. Not any overall improvement from halogen in this instance.
SL1 in Subaru Forester
Intalled these on my 2018 Forester 2.5i. They work great in the projector housing, without excessive glare. I needed to adjust the headlight height after my new tires due to some flashing issues from oncoming cars. After this adjustment there is zero problem with oncoming cars. I have greater and clearer lighting ahead and to the sides - and I love how the headlights look.
Great lights but...
Please pay attention to what people return to you guys so that you are not selling used items. My lights work great as advertised but they were used and abused. The lights looked like they had being installed incorrectly with visible scratches on the locking tabs making them harder to lock into place. The wire insulation was also torn.
