here is my thoughts on the light.
6-140mm pin heat sink
3-Bridgelux VERO29 3000K 80 CRI D
3-bridgelux VERO29SE 5000K 70CRI poke-in
total cost $248.40

using 2 drivers. the one that i already have. the lpc-100-700
and a hlg-185-c1400b
each driver will run 3 cobs,and depending on veg or flower,
you could use either driver on either 3 cob string
example, all cobs running in veg. run the 3 5000k on the hlg-185-1400
full power. and the 3000k on the lpc 700ma, then by using wago connectors. simply switch driver places.
and have the 3000k on the hlg running at 1400m and the 5000k at 700ma
maybe a good all around veg flower light?
and im not adding frame cost, i have a ton of aluminum already

thoughts?

From what I understand about this setup. Running the vero's at 1.4 amp. It will pull about 340 watts. And lumens should be about 56-58,000!!! Wow.

And that is roughly 164 lm per watt. Not bad. All about efficiency

Huh....what are you peeps saying....sounds like Russian....

All the parts needed should be delivered tomorrow. And the light build will begin. Will post pics. Maybe a new thread in diy

Wasn't that hard to build. And it's crazy bright!! Still gotta do some wire tucking and trimming of the zip ties. All and all. Very pleased how it turned out. I will get more pics tomorrow. A better look at it. Show what I used for hanging hardware and what not.
