This panel was 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). 2.11μmol/J.

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, if 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 over the colas later.

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 THC, CBD, and terpene production in plants. But no need high power.

Far IR light is made up of hot wavelengths. This type of IR light is used in grow lighting to help plants like og kush and sour diesel bloom and thrive.

We do not recommend connect more quantity because it will have extra heat because of very high current.

LM281B+ Spectrum Chart

We recommend the LM281B+ model consider the LM301 series is very lack of supply. And the LM281B+ model has about 80% efficiency of LM301B but only half cost which with very good cost performance.

Image below to show the connection, please note the heat-sink and driver are all not included.
