The SL2 Pro combines the next-generation of LED components and technology allowing us to build on the best replacement LED bulb on the market.
The emitting area with TST is minuscule compared to other options on the market allowing our SL2 Pro to mimic the original tungsten filament in your original halogen bulb. Thermal Separation Technology is the latest innovation providing superior heat dissipation and optimal light output while combining these factors into the highest performance compact package!
Every part of the SL2 Pro LED was engineered for reliability, from its full metal construction to the fully-sealed design. The SL2 Pro was put through its paces in our environmental testing chambers - where the bulb lasted through repeated thermal cycles from -40 through 85 degrees Celsius (-40 to 185F), along with a range of other environmental tests. It's also designed with transient protection, to prevent premature failure from electrical spikes in the vehicle. It's even compatible up to 30V! We're so confident in the SL2 Pro, that it's backed by an industry-leading limited LIFETIME warranty. See details at diodedynamics.com/warranty.

Props to Diode! It’s great to see thought out forward progress to proper LED bulbs design. I’ve been rocking your original SLF’s for years with never a hiccup compared to countless other designs and attempts from other sub-name manufactures.
Keep doing the good work, pushing the engineering envelope further my friends. You’re doing the world a service by bringing properly optically focused and thermally managed designs to market.
Your support and kind words are much appreciated, and fuel us to continue on. Thanks for checking out the video!
I'm looking for an LED lamp for my car that is 555 nanometers (nm), which corresponds to the green portion of the visible spectrum. for low light conditions I am also looking for a 498 nm LED to address low light conditions. i'd like 50 to 100 watt bulbs.
Hey there! What vehicle do you have?
Great explanation, Paul!
Why did you decide not to install a thermistor near the emitter to regulate output current/brightness when the chips reach a certain temperature threshold?
Putting the thermistor right next to the LED creates the need for additional wiring and thereby points of failure. Since this is a small unit that's all held within a metal structure, the temperature can be effectively monitored in the main circuit instead for protection against overheating. In terms of "optimization," you'd think that it would be ideal to drive current at a specific level based on the temperature. We tried that with offroad lighting, however, this creates a feedback loop, where the LED hits a certain temp, power is reduced, it cools down, and then power increases, in a constant cycle. Not a good or effective result. We've determined that it's more practical and valuable to allow the bulb to self-regulate at a stable temperature, and monitor temperature only for overheating protection, which is what's being done here.
@@paulmccain1148 That makes a lot of sense - thanks for breaking it down, Paul!
Are there any plans to make the SL2 Pro in the 9007 bulb size? Almost all of my performance vehicles use this size and would greatly benefit from this technology.
Vosla makes a good 9007 bulb. That's what I've personally ran before I did a retrofit
@@96ejdon’t u mean Boslla?
@@toyotabrony nope, vosla it's a German brand. They're still halogen but I have found they put out more light than Factory while being affordable
@@96ejwhat’s the increase in brightness and whiteness of the high performance halogen bulbs?
Are they are as bright as sylvania - silverStar ultra?
@@toyotabrony they're probably warmer than a silver star, I've never done it back-to-back comparison on those but compared to the stock ones they're generally brighter in every size like for like. But if you're happy with silver star definitely get those that's not a bad option at all
Now my question is, how many watts and lumens does both passive SL2 and active SL2 PRO led bulbs make?
And which do u guys recommend the most for low beam and high beams for one of these amazing well made led bulbs?
@DiodeDynamics
Nothing new here, nice educational video though
It is new, new tech, new contruction, very unique led bulbs that they describe in depth about it.
U ain’t gonna see this, with a cooling fan on the different location.
@@toyotabronyPhilips was one of the first (if not THE first) LED bulb manufacturer to introduce TST technology with their Ultinon Pro9000 and Pro5000 models years ago. So yes - besides the top mounted fan, it isn't exactly groundbreaking tech.
