Hi there. I need 660 nm red light for plant growth. I don't have any experience with electronics but I have the following setup from my research on the internet:
What are the adjustments that I need to work this circuit properly?
How many resistors do I need to drop the voltage to the 9-11 V?
Should I consider heatsink without a fan?
How much amper power source should I buy?
I am planning to buy :
