Small Bridgelux EB Gen 2 Build

I'm going to be building a small build using 6 of the 280mm EB Gen2 strips. I want to be able to run them all at 100% if needed but will likely be running them at 75% of max just for efficiency.

I found this power supply that I think would work for the build:
HLG-120H-C700B

I was thinking about running them in series with dimming via a potentiometer just to protect them in case one fails, would parallel be a better option?

I'm going to mount them on aluminum strips mounted under a piece of wood.

Too much driver for only 6 strips. 700 mA is twice their rated current. The HLG-80H-C350 is a good match if you add a couple more strips.

Thanks for the input. I'm pretty new at this, so is nominal drive current the recommended current? In the spec sheet it says the maximum current is 700ma. I was thinking about it that 0ma is the bottom, 350ma is the middle and recommended for efficiency, and 700ma is the max before they start to burn out. I was going to get a 700ma and use the potentiometer to limit to somewhere below that based on what I need. Is this correct or is 350ma the upper limit before they start to burn out?

Yepp! 700mA is the maximum rating and also if you only want to run the strips at 75% or 525mA the voltage exeeds just the drivers minimum output voltage, not very efficient.
If you still want to use a 700mA driver take the HLG-80H-C700B(128vf). In this case 6 1' EB strips(~123V) fits perfect but you need at least c-channels or something similar to adequately cool them.
Many EB series users drive their strips at 150% of the rated current with good results. Keep an eye on the temperatures, as long as they stay below 85°C there is no reason for being scared.

350 mA is the current at which they base their 180 l/w rating. Running them hotter than that reduces the efficiency.

Thanks for the input. I'll grab a HLG-80H-C700B and power them with that with a potentiometer to dim.
