@dbrn32 With regards to drivers. What does the end letter indicate? Such as A, B, or AB like in Meanwell HLG-240H-48A, HLG-240H-48B,HLG-240H-48AB The letters I have bolded.
What do you think of this board?
The Samsung LM281B+ has very high efficiency 165lm/w, it also has very good performance at 3000K color temperature for plants growing lighting, it is not full spectrum LED, but after added the 660nm Red LED will make it very close to sun light.
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, 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.
