"Quantum boards" refer to PCB panels, of Samsung LM561C top-bin diodes. The chips are SMD 5630 size chip.
At 60W, the panels run at 150mA, (well under the 200mA maximum), and the board achieves 184 lm/W. At 65mA, its efficiency increases to above 200 lm/W! Wow.
Our panels are fan-cooled by a 92mm SUNON Maglev fan, and powered by the Meanwell LPV-24-100. This driver offers 88% efficiency, meeting Class V electrical efficiency standards.
Samsung offers a calculator, for determining the efficiency of a hypothetical 'quantum board' (i.e. any X-Y grid of LEDs) using their chip. We chose the highest bin diodes, S6, and the voltage level to maximize efficiency, and arranged a modular lattice of 96 LEDs.
Available in 3000K and 4000K
3000K for flowering
4000K for vegging
Note: We also offer a 320W options, which uses a 94% efficient Meanwell HLG driver.
