QB 288 V2 and QB 288 V2 R spec have 50V-54V DC forward voltage and same driver options will work for all.
DO NOT wire different version boards in parallel. For parallel wiring it has to be all QB 288 V2 R spec or all QB 288 V2 or all QB 288 V1 boards on a driver.
High efficiency boards designed for Horticulture Lighting projects. No Thermal Interface Material is required between the QB board and flat metal heatsink.
- 288pcs Samsung 301H
- Connectors rated 300V 9A
- Estimated LER 321.60 lm/W
- Estimated QER 4.86 µmol/J
- Dimensions 6.833" x 11.25
- Max current per board 3000mA
Flux Characteristics with QB 288 V2 3000K at 55C
|VDC||Current (mA)||Watts at Board||Lm/W at Board (55C)||μmoles/joule at Board (55C)|
- Allow tolerance of an additional 1V while matching drivers.
- Please use this as a reference only.
May require an Aluminum plate or heatsink if running 50+ watts. Heatsink requirements depends on application and power.
While using multiple boards, series wiring is preferable to avoid thermal runaway if a board gets disconnected.

Multiple Boards can be wired in parallel. Different batches of boards may have slightly different voltages. Use only boards from same batch for parallel connection. Do not use different spectrum boards in parallel as they may have slightly different voltages
Tip: Avoid daisy chaining multiple boards as shown in the 2nd image below. This causes first board to handle a large current and can reduce life of board's electrical trace. Wiring as shown in 1st image is preferable.

Maximum 5 Boards can be wired in series. More than 5 boards in series will exceed the recommended maximum voltage of the board connectors and is not recommended.
NOTE: Boards purchased in multiple orders may be from different batches may have different voltages and may not work share equal current if connected in parallel. Use them in series to avoid some boards pulling more current than others.
Parallel-Series Wiring (Advanced)
It is possible to have partial benefits of parallel and series together using some driver configurations. For example HLG-320H-C2800 with 2 parallel string of 2 boards in series.
