PerfectPar™ 650W energy efficient full spectrum LED grow light for single or multi-tier commercial horticulture cultivation in a greenhouse, vertical farm or other indoor facility. This light is more efficient than a standard 1000W HPS grow light. The four LED light-bar configuration provides up to 25 square feet flowering footprint.  Deeper canopy light penetration promotes robust plant growth.

LED Chips
: Top bin, high-efficiency latest generation OSRAM horticulture LEDs. Uniform light distribution and no hot spot. Each light-bar integrates white LEDs with specific red LEDs to create  a tailored full spectrum light for most yield out of LED footprint.

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™ 650W has been optimized 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.

Daisy Chain Connection
: Up to six 650W LED lights (24 light-bar) per 20A circuit.
