I do not use CoBs. I use strips of red, white, and blue discrete LEDs with dimmers on each string of 16 or 21 LEDs.
LEDs, especially red, are very temperature sensitive. The cooler they run the more photon flux produced per watt of electricity.
The heatsink is also the frame of the fixture. The copper pipe's cost is less than an aluminum heatsink.
May I ask where you get those strips? Do they provide the horsepower to match HPS in flower?
