To be honest, I am now looking at Sylvanias or Philips... If I could get just a little more light, they would be fine....
Both Philips and Sylvania have LED bulbs for some replacement duties. It might be hit-and-miss getting the lighting needed for specific purposes though.
From what I am reading, the stock housing is made for halogen bulbs, not LED, therefore, a halogen bulb is going to look 'better" than an LED, in the stock housing. If that makes sense... I think I am going to try the Philips Xtreme Vision. It can't be any worse than the stock headlights that I have now.
On a side note, I spoke with the parts guy at my local Ford dealership and he was saying that it could just be that the stock bulbs are fading due to time. I never thought about that, but that makes sense...
I’ve tested many high end ones and the sylvania Zevo are still better in my opinion.
They actually throw all usable light back at the reflector. They are bright and they have a hugely distinguishable high and low output.
The latter is an issue with a lot of leds these days. They seem bright, but the running lights are nearly as bright as the turn signals which just isn’t safe. I see so many taillights / brake/turn signals like that these days.
The Zevos are probably the best taillight option and they’re around $20 for a set on eBay.
I’ve run them for a couple years, taken them out to try others that are supposed to be brighter and better, but I kee putting the Zevo leds back in.
I ordered the Crystalux XHPs from 4x4truckleds this morning. I think they will be good to go. I did not get the flicker unit (?), so hopefully I will be good to go.
I have a pair of Claralux CL90s in my backup lights and I love them. They're basically the same or very similar as an XP80 bulb from Diode Dynamics. As far as LED headlights and Foglights, yes there are good ones but don't just buy the "brightest" bulb. You want a bulb that uses it's light and the housing as efficiently as possible. That means you want a bulb that creates a "cutoff" similar to the halogen and throws light down the road as far as possible. You can get bright lights but it won't throw. You need ones that efficiently throws the light. You wanna make sure to test them and you may have to adjust your headlights and fog lights a hair down to avoid glare and you'll be good. Id look at Claralux or Diode Dynamics.
While the XP80 may look similar to other market options, the circuit design differs greatly, which has a significant impact of performance, reliability, and longevity. Heat soak plays a major factor in the actual performance of an LED bulb. A good design will maintain the majority of it's output even when the bulbs reach full operating temperature. Some market options will actually lose about 2/3's of their output when they reach operating temperatures.
Our lumen measurements are taken when the bulb reaches it's heat-soaked, operating temperature to provide real-world figures vs. just giving an inflated number.
You are correct that the lumen output is just one aspect of the functionality of your LED replacements. We have recently released our new SLF & SL1 LED replacements, which were designed in-house using sophisticated optical modeling software to ensure the best possible use of factory optics.
Here's a .gif comparison of the photometric testing data taken by our engineering team with the new SL1 vs. OEM halogen in the F-150 Reflector housing:
*THIS IS NOT A PHOTOSHOP* this data comes courtesy of our goniophotometer, and shows how our SL1 retains the same pattern as the factory halogen bulb, but shines considerably further down the road, which is the main goal of improving your vehicle's lighting.
The SLF & SL1 are also the only USA-made LED replacement options, and will outperform every imported bulb currently on the market. This is based on over two years of extensive research by our engineering team here in St. Louis, Missouri.
We will be posting more information and data in the coming weeks about these new options.
Funny because Putco claims their LED bulbs are USA made as well...sooooo are you saying they are lying since you claimed yours are the only USA made LED replacement options? Pretty high claim there that they will outperform any bulb on the market when your marketing photos show one of the poorest bulbs on the market. Why not put it against say the Putco Silver-Lux Pros?

No, we are not saying anyone is lying. We are here to share information about our products, we are not here to directly discredit or bash other sellers and brands. That said, their definition of "Made in USA" is a bit different than ours. In terms of where geographically the majority of value is added in the assembly and production process, we believe our claim is accurate.
I personally haven't seen any photometric data available for any other bulbs on the market, so I'm not sure how you'd be able to make that judgement. Our focus is on delivering an upgrade from halogen, so that's the data we provide first and foremost. Yes, we have benchmarked against many LEDs available on the market. We'll add the Silver-Lux to our list, but it is impractical to test the hundreds of generic designs in hundreds of OEM housings - especially when all of these generic imported designs tend to provide similar results in both output and quality of assembly/reliability.

Fair enough but I'd like to believe you'd put your bulbs against one of the industry leaders, Putco, rather then the cheap crap you find on eBay/Amazon (which we know is garbage but $20 on impulse is tough to pass up).
You also stated "The SLF & SL1 are also the only USA-made LED replacement options," which is not true they are not the only USA-made led replacement options... as I pointed out, Putcos are USA made according to their website. So you may want to change that part.
How many lux/lumen (actual) are your bulbs? I see it says "Street Legal Output" on the website, so are your bulbs less then 32 candle power at the hot spot?

Thank you!

Would you be able to add some sort of key or lumen output to your GIF so that we can see the lumen output and what each color would represent?
Ex. I see that in the 1st (stock)GIF that there is a tiny green dot. What is that representing as far as lumen output at that spot? In the example for your bulbs the green extends to the approximately 47 yard mark, but I don't know if that is the full 1500 lumens. Also does that mean that the stock bulb is putting out 1500 lumens at that 20 yard mark? Why is the same graph (GIF) for every bulb. One would think that they would be different for every bulb, especially between high and low bulbs. I'm not sure what the 251x, 101x etc. means?
Also what is the difference between the SLF and SL1? Is the SLF just for the fogs?
Thanks.

We will be adding much more information to the listings, and producing information videos I can post soon. The main purpose of the .gif is to demonstrate that the output pattern is similar to the OEM bulb, but throws light further down the road.
I'll see if our engineers can add a key to these photometric testing graphs to make them a bit easier to understand.
It is indeed different for the high & low beam comparisons. We just wanted to get some of this data out there for the F-150, since it was our primary focus housing-wise. Rest assured, there will be plenty of data available.
The SLF is a lower-powered version of the SL1, and doesn't utilize the fan & shroud portion of the design. It's a less expensive for fog lights than the SL1, but performs pretty well since it has the same optical design.
