I am not talking pictures on the internet.

Of the angel eyes you bought from us, which ones are you comparing that did not have a discernible difference in brightness when wattage was increased?

In case you haven't realized this thread is dead and the original post is removed. Asking a member which items he has used from us is not an argument, it's a question and a valid question since the original thread is based on wattage and products we offer.

I'm also pretty sure arguing with vendors and telling me what to do is a direct violation of forum rules.

How was this number measured? Is this the summed theoretical max output of all the emitters, or some other method?

These are actual numbers from Cree. They offer this awesome tool that will allow you to calculate Lumen output, Efficiency, Overall wattage etc. All you need to know is the type of the LED, the bin grouping, and the drive current of them. Since we design our own product we of course know all of that information including the exact LED bin code we are using. Based off those numbers it calculates 906 lumen for all 4 white LED's. As well since our lights do not dim at all this number is accurate for all modes of the car's operation.

As you increase the color temp white decreases and blue increases in overall lumen, but the change is pretty much even the entire time, within a few lumen. It doesn't create a large enough difference that you eye could tell the lumen difference between 5000k and 12,000k.

I am not talking or saying that the bulb/upgrade itself is not actually brighter. I am talking about once installed into the headlight how it operates. From my experience and seeing lots of local BMWs I don't see the difference.

Two side by side outside of the car. Sure. Probably brighter.

Good stuff. I do have to give you credit in that you actually understand how LEDs work, how they're driven, etc. That's a lot more than can be said for all the vendors rebranding Chinese products.

You mentioned that the calculation is done based on drive current, I assume you measure current at the LED with the bulb connected to its driver and then to the car in order to get real world numbers? Based on the fact that your bulbs don't dim, I'm speculating you use a constant current driver in the form of a DC to DC regulator so it shouldn't make a huge difference whether the bulbs are connected to the car or not, but still.

Thanks man. I've been designing LED Angel Eyes for over 6 years now so yes i feel like i do have a pretty extensive knowledge of how they work, the drivers behind them etc.

The driver we are using in the LUX H8 V4 we designed so we know exactly what happens in it and the nominal drive current as well. Regardless of whether you have the car on, car off, headlights on, or just plugged into a bench power supply you will get the same output to the LED's.

Many of the products out there don't accommodate this, so lets say when plugged into a bench power supply the output will b 100%, when the car is on it will be around 80-90%, when you turn the headlights on it does down closer to 30-40%

So you haven't done a side by side of our lighting systems comparing say 40W to 80W? I'm just trying to prove a point that people spread rumors way to quick and they are largely blanket statements with no controlled experience.

In real life, if you were to try our 40W then upgrade to our 80W and do a side by side comparison there would be a real physical difference in brightness and one that would appease the end consumer.

If there was no discernible difference I would have a lot of angry customers and furthermore I wouldn't even bother selling them.
