@diodedynamics Hi. I have been waiting for a review and comparison of the SL2 H1 bulb as this one is by far the most controversial one. Most manufacturers like honda required some sort of adapter with the H1 bulb. That's why yours are the only reputable brand H1 in compact form on the market. My 06 CR-V uses two pairs of H1 for high and low beams. I would appreciate it if you guys made a video about the H1 SL2 comparing it to the halogen. I already have them in the shopping cart. Thanks
Now even if it’s not DOT approved, even if u say not good to put led bulbs in a low beam headlights to use in an area of no lights or city lights. We still would rather upgrade led bulbs on either projector or reflector. No matter what. It’s a huge safety benefits to see better and be seeing better. In our states, we have no issues at all putting led bulbs in projector or reflector headlights.
So, a friend of mine (we're engineers) asked me around 2015 about the feasibiilty of an LED replacement bulb for headlights. I told him don't do it, the technology isn't there. It still really isn't - but it's close-ish. What you don't want is a diode hanging way out there on the filament location. Instead, you want a fiber coupled blue laser, with the PHOSPHOR conversion out where the filament is (talk to a company called Intematix, who make inorganic phosphors for light conversion. This means you can get the heat down to the base, where there is more area you can use for dissipation without obstructing the light distribution field (you can still reject all the heat into the housing). Imagine having a fiber that is the shape of a filament, covered with the phosphor in about the original dimensions of the filament, and the heat all at the base where it can be rejected into the housing. Similar to the signal bulbs - "there was an attempt"... the Xenon Depot 7443 XTREME VF bulbs (no affiliation, I bought some, wasn't happy), try to use a light pipe to move the LED parts down out of the way, but IMHO they didn't "go big" enough. Back in 2020 I recommended to them making the light pipe longer so they could replace the bulb base and put both the driver and heatsink in it, nothing ever came of that from them. Diode Dynamics is one of a the few LED bulb manufactuers I've seen using an integration sphere to measure light output - I can pretty much gaurentee that none of the Chinese bulbs do that. But I'm still unhappy with amber bulb intensity in daylight. Best LED replacement I've used has ben a Whelen "factory option" from Ford in my 2015 Police Interceptor - they have somethign they called the "LED Front Lighting Solution" which included LED hide-away strobes, but the amber turn signals had to be integrated into the front firing white strobes in the turn signal location. not only did Whelen nail the bright/dim ratio so that YOU CAN ACTUALLY TELL THE DIFFERENCE, they got the bright output correct.
I love all the videos you guys put out. Not just because I’m affiliated with you guys, but the transparency you give as to specs and the design/dimensions is unmatched.
And yes I’m a huge fan of any type of high quality reputable brand led bulbs way more than HID. So I already subscribe to u guys. I’m seeing better potential than ever before now. ❤️🔥❤️🔥❤️🔥
Question! Are you working on a dual fan model? Putting the fan above the LED is genius and I wonder just how much brigher and efficient a model with a traditional fan 'base' + this new fan would be !
Any beam pattern views with the sl2 pro on 4th gen ram with the quad headlight. Also does the high beam led fit in the factory housing with the dustcap. I personally have a lot of your products. Fantastic.

Looks promising. A few questions... What's the CRI? The rated luminous flux of 2400 lumens-is that RAW lumens, or EFFECTIVE lumens? Do you have any plans for warmer color temperatures like 4000K? Thank you
CRI is the color rendering index. Scored from 0 to 100. At 0 all colors look the same, at 100 actual true color of the object is revealed. Like daytime on a sunny day. You get the true color of grass, trees, rocks, animals, ect. The closer the score to 100, the better. Eg. At night, you will pick up a deer in dew covered grass in a ditch way better, with a cri that is 100 than say an light that has 50 or 60 CRI.
@sherlock_homeslice sorry, misread your comment. As for sl2 CRI rating, I am not sure. That would be interesting to find out. I personally have only seen some really high quality leds in the past have a maximum of 70 CRI, but that was a couple years ago. I would hope that Diode Dynamics would have at least that at minimum. Hopefully they will get back to these comments and answer them.
Hey there! At Diode Dynamics, we prioritize the performance characteristics most critical to automotive safety and effectiveness in our lighting products. CRI is less relevant in automotive lighting, where the focus is on visibility, beam pattern, and luminous intensity to ensure safety under various driving conditions. Automotive standards emphasize these aspects rather than color accuracy, as nighttime visibility relies more on light intensity and distribution than on color rendition. Thus, we do not publish CRI values because they do not provide meaningful information in the context of automotive lighting applications. Regarding the output - the 2400 lumens is a measured/effective lumen measurement per bulb. Though we don't have any plans for other color temperatures at this time, we will suggest it to our team for you! Hope this answers your questions!
Certainly! While we don't have confirmed data on the MTBF (Mean Time Between Failures) of the top-sided cooling fan in the SL2 Pro, we stand behind our commitment to quality with a lifetime warranty on these bulbs. This ensures that regardless of which component might require replacement first, you'll have peace of mind knowing that we'll support you for the long haul.
Basically they stand behind their product, which means they know this will truly last for a very very long time. And if anything goes wrong, they will be able to replace it. At anytime
We have not had any reports of radio interference on our SL2/SL2 Pro LED replacement bulbs on a 2019 WRX. Diode Dynamics offers a 30-day return policy that includes a free return label and no restocking fee if you want to give these a try!
@@diodedynamicswill these still give the bulb out warning on finicky bcm model vehicles like fords and Chryslers. I bout a pair of the sl1 and every time I turned them on I would get bulb out warnings every 5 seconds so I pulled them years ago and put them in a box.
The focus of the light is generally much better, however this all depends on the housing they are installed in. We'll work on getting better comparison images in several housings in the near future! Stay tuned.
You're welcome to test ours out! We offer a 30-day return policy should you be unhappy with your purchase for any reason. No restocking fees, no administrative fees, no return shipping fee for US customers, and no hassle! www.diodedynamics.com/returns-and-exchanges
Awesome. Loved my SL1's in my 16' Charger & 19' F-150! Will the H11 SL2's work in the E70 LCI BMW X5 (2013 MY)? It has that weird turn the steering wheel left or right and the fog light on that side illuminates...

I order the slf fog lights in cool white but When I got them they said I got an upgrade the sl2 instead but when I install them in my car the leds where yellow, but the box that those came in It said they where white 😮
Hey there! Sorry to hear about that! Feel free to give us a call at 314-205-3033, Monday-Friday 10 a.m.- 5 p.m. CST, or shoot us an email at contact@diodedynamics.com, and our in-house US service team would be happy to swap those over to white for you!
If you have have halogen factory headlights, the low beam will be H11 and the high beam is 9005. We offer both on our website! www.diodedynamics.com/products/led-bulbs/foglight-drl.html
These are not. We decided as a performance LED manufacturer, we would delegate certain smaller projects to suppliers overseas, to give us more availability to focus on much bigger projects that are currently in the pipeline for our production team in Missouri! Be sure and stay tuned for those releases in the coming months!
@DiodeDynamics Now my question is, why did u guys go from Diode Dynamics - SL1 with an external driver. To Diode Dynamics- SL2 PRO with internal driver? I love both version of them. But I’m curious of why go that route?
@@contagiousingenuityagency5273 eliminating the external driver allows for expanded fitment across all vehicles. Many vehicles couldn't use SL1 bulbs as the back of the bulb was larger with dust caps or external driver wouldn't fit inside the headlight housing if sealed.
The SL2 Pro offers 2400 lumens, while the SL1 offers 1400 lumens. This is the perfect upgrade for any offroad setup while maintaining the same output pattern of halogen lamps!
@@diodedynamics so basically it's a lot more light. Would be good for a fog light? I have sl1 as a fog light (with a normal style put the bulb through the back housing) 2013 accord V6 sedan
@@ganzonomy Sure thing! As long as you have a halogen factory fog light, you can upgrade to the SL2 Pro. We offer them in H8 bulbs as well! You can check them out here: www.diodedynamics.com/h8-sl2-pro-led-bulbs-pair.html
