Whatever you decide to go with COBs or strips you should write up a build in here
Yeah, I'll update it with what I have going when I build it.
I decided to go with a thrive v13c 5000k and a lumiled 1204 crisp white gen 2.
We will see what happens for plant growth, I don't expect much par out of these COB's alone, but the initial test should come close to my 3 watt diode setup I've used in the past and those grew plants great at only 25-40% (I didn't know that the par was probably really low).
What I'm more interested in seeing is how the plants respond to the 5000k thrive COB spectrum along with the violet peak in the crisp white COB.
It's worth noting that this fixture is likely going to go over the waterbox clear mini 6 instead of a standard 10 gallon as I had originally planned. I've got a ton of ideas floating around of what I want for a new tank and decided since I already have a 55 gallon that I don't want anything too large.
Got the chips in.
I haven't been able to test both together because LEDSupply sent me the wrong LDD driver, so I'm in the process of getting that fixed.
I tested both individually. The 3000k crisp white is as expected more of a white-yellow/orange however it doesn't discolor the greens like my 4000k's would. It adds a nice warm neutral white tone to the tank while also making the plants pop.
The Bridgelux thrive v13c 5000k is nice; it doesn't wash out the plants despite being an extremely bright neutral white light, quite the opposite really, the plant coloration is rich under the light.
I've forgotten what high CRI whites look like on a tank, at 90 CRI for the lumiled and 95 on the bridgelux the plants display much more detail when compared to a nicrew classic plant light (one with the pinks and the greens) that is normally on the tank.
While going through the process of ordering the heatsink I realized that for the price I would be paying to build everything custom it was going to be cheaper to go with a slim MakersHeatsink kit. I'm glad I did, installation of the LED's took 2 minutes, got the 12" fixture for the waterbox clear mini 6 and after 3 hours of testing the temps, the fixture was only slightly warm to the touch around the diode.
