What is Quantum Board?
 
Quantum Board is a led lamp model in which many small led diodes are attached to a flat board. The diodes are arranged in rows operated in parallel by a high power constant current driver.
Contrary to its very simple appearance, it provides many advantages in terms of use.
Quantum Boards give you more light output while consuming less Watts.
Because light is emitted from many points across a large board, it has a more direct path to shadows outside of coverage. In other words: it provides a more even light spread.
Harvest Master Quantum Board 200W Eco emits a full spectrum white light that includes light of every visible wavelength.
Quantum boards are usually mounted on a thin piece of aluminum (or sometimes a heatsink) sufficient to passively cool the diodes. They do not need active fan connection.
On average, Quantum Boards cost less than traditional led lamps.
