* Voltage calculated using sample board. Voltage may be +/- 4% for boards in different batches.

** Min values calcualted using AZ Voltage Bin, Max values calcualted using A1 Voltage Bin

** For more details refer to Calculator here. Use values LM561C, 3000K, 80 CRI, AZ or A1 Voltage Bin, S5 Flux bin. # of LED as 304x (number of boards). Change IF_Drive mA to see lm/W and flux for different power.

May require an Aluminum plate or heatsink if running 50+ watts. Heastink requirements depends on application and power.

 

Note for Parallel Wiring

All boards are tested at 700mA and a test Vf is written on boards.
For circuits with multiple parallel boards on single driver it is best to group and use +/- 0.1Vf boards together to ensure they share current equally.
For series or single driver per board matching Vf is not important.
If you re-order boards to mount them in parallel with old boards you bought, give us this Vf number in checkout notes so we can give you boards with similar voltage.
