Led light not lighting up fully

[Seanneedhelp]

Have a 720w 8 bar style led with 3 drivers. Woke up this morning and 3 of the 8 bars are just barely lit up while the others are running like usual, tried driver on other bars and it works fine. So assuming problem is in the 3 way harness that connects the 3 bars to 1 driver Took apart and white neutral wire has a little discoloration right where it connects to the light on all 3 bars. Any ideas? Could the neutral not getting a good connection cause the leds to just barely light up?

Your symptoms suggest parallel connected banks of series connected LEDs. Most common configuration is one driver for each series connected bank of LEDs, but your symptoms suggests parallel connected banks.

Understanding the configuration aids diagnosis. Post a picture of the driver label.

Grow lights?

If 720 watts is the LED power and not an HID or incandescent equivalent, it would translate into almost 100,000 lumens. You could fry an egg with that much light.

21,000 lumens is the biggest single LED light fixture I've ever seen. It consumes 150 watts.
