Calculations:
CXB3590 36V Electrical Characteristics:
Estimated voltage at 700mA:
37.25V @ 2800mA (Tc = 25C)
34.75V @ 1400mA
2.5V from 34.75V = 32.25Vf assumed at 700mA.
3 x 32.25V = 96.75V

Efficiency of HLG-80H-C700A in this circuit:
96.75V / 129V = 75% load, just over 90% efficient according to the graph.
Fully dimmed: 420mA / 700mA is 60%. 60% of 75% equals 45% load and the efficiency is just under 90%.

Cool. i run the cxb 3590s 72v @.7mA. Plants love em so far still acclimatizing.View attachment 528788
its only been a couple days. only difference noted so far is an increase in odor. it might be from the uvb or maybe just a factor of the plants maturing.You find any real benefit from the uvb?

I was thinking that any benefits probably would not be noticeable until closer to harvest.
I did do a bunch of research and i thought that science does support the claim of uvb increases potency. We shall see in a couple months.
sure i will certainly post my impressions.I didn't realize this was your first round with it.
When you are done, I would be extremely curious if you notice any difference. Even if you "think" you notice a difference... I'd be curious.
Despite the science, I've been told by a fellow grower that it didn't make any difference. But there are so many factors involved we don't know what is responsible for a lack of noticeable difference. I think I'm going to add one eventually.
