    My 8-3590 cob diy.

    I leave my fans running even when the lights are out. At lower voltages I'm afraid they may fail to start and I run mine under 5 volts sometimes.

    Why no red COB's?

    Higher bin 3000k are becoming available even in high cri. I'm waiting for the 2700k cxb-3590's personally or the new generation that is supposed to be based off uv instead of blue.

    My 8-3590 cob diy.

    Will the fans shut off at lights out? The red leds could cause issues if left running after dark.

    CXA/CXB 3070 build

    It's the 80w series, the 42b is capable of 1950ma. There is also a 60w series but I am unsure which models are available. The a series only allows 50% dimming and I wanted more flexibility. It's real easy to put a potentiometer on them.

    CXA/CXB 3070 build

    I would run the two higher kelvin crees on a dimmable and the other three 3000k on another. This would give you control of the spectrum. You could even run the 6500k and the 5000k on their own drivers but I still recommend dimmable versions. I use the hln-80h-42b on each of mine but it is a...

    CXA/CXB 3070 build

    I run a similar size cab with dimensions 20w x 11d x 29h with 2 cxa3070 3000k. I am getting bleaching issues when running much over 40w per cob. Are your drivers dimmable? You might end up with too much light (strain dependent)

    CXB3590 1500W

    You could use the hln-80h-36b if you wanted to use the potentiometer

    Possible CXB3590 Conversion

    Output Voltage range and current are the numbers needed to know if it will run a cxb. The heatsink will need to be enough to handle the heat and will possibly need a pc fan added. You might be better off just building from scratch and selling the ufo if possible.
