QB132

Amzon Prime Qb288 Link

High efficiency boards designed for Horticulture Lighting projects. QB 132 Boards can be powered upto 75 watts. QB132 are 36V and can be used with standard drivers(HLG-185H-C1400, HLG-240H-C1750) used for CXB3590. Ideal for use in grow tents or grow area with reflective walls and grow spaces with limited height. No metal heatsink or thermal paste is required .

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

** For more details refer to Calculator here. Use values LM561C, 3000K, 80 CRI, AZ or A1 Voltage Bin, S6 Flux bin. # of LED as 132x (number of boards). Change IF_Drive mA to see lm/W and flux for different power.

Board does not require heatsink for operation. However derating power may be required is backside is blocked and unable to help board with cooling

The notes below are provided as a designs ideas and are not instructions to assemble a lamp. Do not touch live boards as they run on high voltage and may have exposed solder contacts that can cause serious shock. Driver DC side may hold charge for few seconds  even after disconnecting AC mains and could cause shock. This is not a safety guide.

While using multiple boards, series wiring is preferable to avoid thermal runaway if a board gets disconnected. MW HLG series CV drivers allow Voltage adjustment and can be used to limit board wattage by limiting the voltage.

 

QB 132 comes with single Molex connector . 300V rated Molex connector allows upto 8 Boards in series. Recommended drivers
