You could use some help.
Switching from almost any other type of lighting to LED lighting is probably going to increase lighting efficiency. How do LEDs perform at growing
plants? I'm not sure and I haven't studied this...it would depend on the frequency distribution of the light produced and the best frequencies for
the plant. Obviously if the LEDs were green, it probably wouldn't work too well, since green plants reflect a lot of green light.
But none of this has anything to do with coils. You can regulate the input voltage going to the LEDs with various circuits, it doesn't have to be a
And here's an example of how easy it is to mislead someone with efficiency claims. I can claim I can add a 4th LED to the same circuit that was
running 3 LEDs before, without increasing the voltage. So running 33% more LEDs on the same power will revolutionize the industry, will it not?
No, it will not, but this is the type of misunderstanding taking place with some Rodin coil experiments. You also have to measure the light output
from the LEDs to see if they are really more efficient or not. If you're using less power, and the LEDs are dimmer, then that's not really an
improvement in efficiency, is it?
Here's an example:
Connecting a fourth LED in parallel does not increase the total current. It just makes all the LEDs dimmer because the same current is shared
between more LEDs.
So if you put a Rodin coil in the circuit, how do you know it's not just making the LEDs dimmer? There are other ways to make LEDs dimmer besides
using a Rodin coil, and yes it uses less electricity, but it's not necessarily more efficient, because the efficiency depends on light output which is
Daniel Nunez made this same mistake with an electric heater. He claimed he was saving electricity, which he was, but because he lowered the effective
wattage of his heater. The coil didn't increase efficiency.
