My plants seems to be able to handle much more blurples than white light. Makes sense i suppose since blurples are much less efficient so watt per watt, plants get more photons with white lights.
These Osram diodes are right up there with the best of best. From what I read, just a wee bit lesser than Samsung top bin mid power diodes. So they should work in the same awesome way. I've had plants stressed at 45cm at only 185W. The board is 90cm x 20cm and can max out at 350W so only a little more than 50% power. Thats why I asked.
With such high efficiency diodes, dimming is quite important imo. But maybe there is more to it than we know. While I may have mentioned areas that are lacking, perhaps there is a sweet spot created with the angle and lenses. Not to mention the added spectrum that they added to the white diodes. Now that I mention it, the added red and blue (maybe lenses too) might be why they can get close to young plants without burning them.
In your hands, these lights will be growing beasts!
