Part 2: LED Grow Light PCBs
You may worry about the drop in LED working efficiency when the temperature gets high. But you don't have to, if your LED grow lights use quality PCBs that can dissipate thermal quickly.
Most of the LED grow lights PCBs are aluminum-based. Aluminum PCBs from PCBHERO have a thermal conductivity of 1W/mK to 9W/mK. This thermal conductivity is enough for the needs of most LED grow lights. From PCBHERO, aluminum PCBs for LED grow lights can be single-sided, double-sided, flexible, single-layer, and double-layer.
However, if you want a better thermal conductivity of the LED grow lights, you can also choose ceramic PCBs for your design. Without a dielectric layer, ceramic PCBs have better thermal dissipation than aluminum PCBs. From PCBHERO, you can have alumina substrate PCBs and aluminum nitride PCBs manufactured.
Besides aluminum PCBs and ceramic PCBs, from PCBHERO, FR4, copper, and glass substrate PCBs are also available for LED grow lights.
