Thought I'd dive into the LED light ceespool of marketing. Well, I didn't learn much so I'm guessing at most and the rest is wrong but I can't tell which it is what. I bought the LEDs and driver, made a box, drew out schematic, made a dot pattern and so much more. Here's the dot pattern. Imagine the picture here. The darker red dots will be 660nm. Lighter red dots will be 625nm. Blue will be 450nm. And the pink dots will be from 380 to 700nm. Still making decisions. The box that the circuit board will be mount on is 9 x 9 x 4.5 ( inches). I just bent up some thin aluminum. I'll add the duct holes layer. This will replace the mh fixture. So I made the box to fit in that area . The cabinet this goes in is small and I want to vent any heat.
