Spider Farmer SF1000 LED Grow!

Volts in the example provided by Mimed is referring to at the wall, which goes into the driver and sends out volts to the LED's. Volts from the wall have no effect on the diodes. As long as the driver can handle the walls voltage which every light can...

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.

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. ;-)

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.

If you have 4 fixtures pulling the same watts from the wall, how does the number of diodes effect the equation?
Click to expand...
Each diode can handle a certain number of volts.
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.

Depends on the amperage.

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).

Yes less amperage, less than half but just slightly. but the diodes are a physical part of the fixture.

The driver actually has a stepdown transformer in it of some sort. It drops the voltage way down to like 10 volts.

If you're running parallel.

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.

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.

I was just trying to show that parallel and series require different voltage and amperage.

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?
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 took it down because I don't want that picture on my profile.

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.

What do you mean by separates?

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.
