2 boards were wired in series to ensure same current passes though.
Remote Driver.
Test at 700mA
700ma per board is 75 Watts per board.
Non Anodized was 52.2C -52.6C
Anodized was 46.4C -46.5C
T Ambient 22C
Looks like the anodized heatsink is running 6C cooler than the Non Anodized
Test at 1050mA
1050ma per board is 115 Watts per board.
Non Anodized was 65.4C
Anodized was 58.2C
T Ambient 22C
Looks like the anodized heatsink is running 7.2C cooler than the Non Anodized
Notes:
Installing driver on top of the heatsink will reduce heatsink cooling.
With no air movement Boards on heatsink can run at 700mA with driver on top of heatsink.
With airflow in grow space 1050mA will be fine too with driver on top of heatsink.
Adding a spacer between the driver and heatsink to elevate the driver will also improve performance.
