@Carlos Andrés Toro Good point—and 48V DC definitely helps with installation, safety, and maintenance.But the weak link is still the power conversion. LED drivers are non-linear loads, so they inject harmonics back into the system. That’s where total harmonic distortion (THD%) becomes the real metric to watch.The example I mentioned (three faulty drivers driving ~900 mV) was a rare failure case—bu ...

Carlos, Alfredo—great discussion, and I agree this is an area that doesn’t get nearly enough attention at the farm or technical level.One aspect that’s often overlooked in lighting conversations is the electrical quality of the lighting system itself. LED fixtures are non-linear loads, and depending on driver design, they can introduce electrical noise into the farm environment.We were recently on ...
