Those look really tasty, Brandon.
That's how I described how I've been doing it. I started with a budget light, a GalaxyHydro 300, pretty cheap, but did the trick. I let my plant vet a little too long, and got a little too big for the light's footprint. My buds weren't larfy, but they weren't very dense either. Kinda like marshmallow density. Very very frosty, though. A popcorn nug would light easily, give a nice, thick, greasy plume of smoke, and the bud would burn away to a very small wisp of ash.
Now I use 2 of those and a Roleadro COB 400 that shines white, not purple. I like it for that reason alone, and it's about the right size for the plants I grow. My buds are denser, but could be better. So I'm saving up for either a ViparSpectra 600 reflector or similar vs an LC315 or similar LEC.
Instead of measuring and calculating, I've been slowly adding more smaller lights instead of getting one giant expensive one, and then play with distances and arrangements, and all that, backing off when I think it's too much. You know, give the right amount of light for the size of plant as she seems to need it. It's not the most efficient way to find what works, but it's the way that I enjoy the process of discovery most.
