I was wrong it is a 50w COB which means my China 1200w led is falsely advertised!!! It’s really a true 300w with (6) 50w COB led full spectrum. That’s why the true wattage is 250-270 Watts it’s 300w but loses that 50w-30w from draw and current changes in the circuit to power fans, drivers, etc to keep constant wattage and your lights won’t dim while running.
