Product: KQO 120W LED Grow Light PCB Boards with Samsung LM281B+ 3000K 5000K UV and IR Full Spectrum Panel Lighting PCB Kit
Brand: KQO
2pcs / pair 120W PCB Panel with 3000K+5000K+660nm+UV+IR
 This panel is designed base on the Samsung high efficiency LM281B+ SMD 2835 LEDs(176pcs 3000K+72pcs 5000K), mixed 660nm Red LEDs (32pcs) and less UR /IR LEDs (4pcs each).
 This combination will be suitable for the entire growth process of most plants from seeding, germination, flowering to fruiting.
 The advantage of 3000K has plenty blue for full cycle, it will be very good if you want to make veg/flower rooms. 
The advantage of of 5000K for veg is that your get tighter internodes, which gives you a more balanced distribution of light .
 Red light (660nm) Does its best work in the flowering phase.
 A higher intensity of red promotes a higher yield.
 UV has been shown to increase the amounts of plants. But no need high power.
 Far IR (730nm) light is made up of hot wavelengths.
 This type of IR light is used in grow lighting to help plants bloom and thrive.
 ( Please note this light is Invisible ) Power Driver to Use Plese check the spec printed on the PCB board: 48V/900mA~2700mA.
 So we should use a power driver which the output Voltage cover 48V ( 40~48V is ok) and output Current cover 900~2700mA.
 ( Working at 900mA will have the lowest brightness and power, 2700mA will have the max brightness and power).
 If we connect 2pcs PCB boards in parallel connection, voltage no change, but the power driver should have double output Current (900~2700mA * 2) to make it work.
 If we connect 3pcs / 4pcs / 5pcs in parallel connection will be the same rule as above.
