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 120 with DC barrel connector is recommended for 1 or more boards in parallel with max 3A . Additional boards connected in parallel share the power of driver. best suited for lower power application (max 70 watts). Recommended drivers
QB 120 with Molex connector is recommended for 1 or more boards in parallel or in series. 300V rated Molex connector allows upto 10 Boards in series. Boards feature connectors on each side for daisy chaining power to next board. for higher power parallel application, wire each board separately without daisy chaining to avoid voltage drop after first board. Recommended drivers
* HLG series drivers are CV+CC . Driver with 54V can be used instead of 48V. However power will reduce by 10%-15% . example: HLG-120H-54 can be used instead of HLG-120H-48
