I do like the idea of a quantum board and 330$ for a 260w isn't too bad.
How is the penetration? I understand they have 120/288 and 300 somethings, regarding the amount of diodes and the 260w/288 qb would have less than 1w diodes, wouldn't this have less penetration compared to 5w diode led panels?
IE a mars hydro with 3000k Leds
