circuit

I want to built an LED grow light from scratch but I'm not sure what to look for when wiring in series and parallel on the same board. I want it to have different types of LEDs with different wavelength, like the Spider Farmer SF4000 or the SSK-272-RR-V2 for example, so I have to deal with...

Thank you in advance for your help and please excuse my lack of knowledge or if my terminology isn’t accurate. I am hoping someone can help me answer a question or two about running some Quantum boards using Meanwell drivers and I want to make sure I’m not overloading a 15 Amp circuit, as well...

So I have 2 areas, 12ft2 & 8ft2. I want to run em the cheapest way possible, while maintaining at least 160+ lm/w efficacy. Thinking... [8] Getian 2828 @37.5w ~170 lm/w [11] Getian 2828 @41.0w ~160 lm/w [1] 480h-36a To the point of the thread, has anyone used a relay, timer, resistor circuit...
