Volts from the wall have no effect on the diodes. As long as the driver can handle the walls voltage which every light can, wall voltage doesn't matter.

That is how I read your post.
No they will all be in the same range for the same wattage and diode type
Oh i did say that. I should have said nothing. Lol.

Not quantity of diodes though.That is how I read your post.

Sorry @BigCube i shouldnt have posted but i couldnt take the comment i got started with. And this is one of the reasons i turned the sf rep down for a free light. Again sorry. I should have expected what i started. Oops. ;-)

If you have 4 fixtures pulling the same watts from the wall, how does the number of diodes effect the equation?Not quantity of diodes though.

Ah yes it does. If you have 240 volts going into the driver at 1500 watts you have over twice the effective power as 120 volts with 1500 watts. The higher the voltage the more economical the fixture becomes. You will find commercial grows will use 240 or 277 volts because of the economy.Volts from the wall have no effect on the diodes. As long as the driver can handle the walls voltage which every light can, wall voltage doesn't matter.

Each diode can handle a certain number of volts.If you have 4 fixtures pulling the same watts from the wall, how does the number of diodes effect the equation?
A diode that has 2.5v and 100mA going through it will be 0.25w.
2 diodes that have 2.5v each and 50mA going through them, will also be 0.25w but will produce more light and less heat.

Sorry that's wrong^ I miss read your post.
The driver only lets a certain voltage through. It doesn't consume all the voltage it gets.
And to what you said about the 1500w lights at 120v vs 240v, the 240v is more efficient because it means lower amperage (but more diodes).

Again Watts divided by voltage equals Amps. Replacing the equation 240 volts at 15 amps is over double 120 volts at 15 amps. Still over double.Depends on the amperage.

Yes less amperage, less than half but just slightly. but the diodes are a physical part of the fixture.Sorry that's wrong^ I miss read your post.

The driver actually has a stepdown transformer in it of some sort. It drops the voltage way down to like 10 volts.Sorry that's wrong^ I miss read your post.

Parallel has nothing to do with it. A parallel circuit has two or more paths for current to flow through. Voltage is the same across each component of the parallel circuit. The sum of the currents through each path is equal to the total current that flows from the source.If you're running parallel.

That is inside the fixture. So far everything that has been discussed it about 4 fixtures being in comparison. Nothing to do with different voltage and amp requirements for diodes within the fixture.Each diode requires 2.5v to turn it on.
light 1 requires 5v and 100mA.
light 2 requires 2.5v and 200mA.

Let me draw a new one for you to show how lights can be different if they have the same wattage and diode type.

Did you take your picture down?That is inside the fixture. So far everything that has been discussed it about 4 fixtures being in comparison. Nothing to do with different voltage and amp requirements for diodes within the fixture.
The example you show would require separate connections to the boards to achieve varies voltages. Quantum boards correct me if I am wrong, but they only have 1 positive and 1 negative lead.

I'm not actually sure how those companies run their quantum boards. The connection separates because it is in parallel, that is what I'm saying.

Ok that picture really doesn't matter, I'm working on another one that actually applies to the argument.
If you really want me to explain it to you, then I will after but it doesn't apply to the argument.
