BLI PerfectPar™ 330W full spectrum LED grow light has two LED light-bar. It provides a flowering footprint up to 13 square feet. Plug and play design for commercial horticulture cultivation in a greenhouse, vertical farm or other indoor facility. It is an ideal light for grow tent and basement.

LED Chips:  Top bin, latest-technology OSRAM horticulture LEDs. Uniform light distribution and no hotspot. Each light-bar integrates white LEDs with specific red LEDs to create optimized full spectrum lights for maximum yields.

Independent Control of White and Red LEDs: Dim-to-off, independent control of white and red LEDs provides broader choices over plant light spectrum using a 0-10V dimming controller or a potentiometer.

54% red spectrum: PerfectPar™ 330W has been designed for 14%-30%-54% blue-green/yellow-red spectral power distribution respectively. If desired, amount of red spectrum during vegetative phase can be reduced by dimming red LEDs.

LED Protection: We use Dow conformal coating on LEDs to protect against moisture and corrosive environments.

Light Fixture: Rugged construction. Durable and light weight.
