Why do you have to run them in series? The HLG-320h-48(A or B) will do exactly what you are looking for if you wire in parallel. The driver datasheet says it maxes out at 6.75A, but Meanwell rates these drivers very conservatively. You will likely get the (4x1.8A=) 7.2A you need to run the 4...

The data sheets for both the H- and F-series (page 14) list the diodes used as LM561c . I can't find any information regarding binning of those diodes. Edit: I see tomate was quicker on the draw.

A couple of the Samsung F-series Gen3 finally showed up at Digikey, although in very limited quantity and selection. Here is the 3500k, 560mm, double-chip version: https://www.digikey.com/product-detail/en/samsung-semiconductor-inc/SI-B8U521560WW/1510-2222-ND/6624006 8800lm, 171 lm/w, $27...

Two of 8 EB strips (1120mm) I got from Digikey were damaged. Several of the quick-connect caps were broken off and were not in the packaging. Four or 5 chips toward the center of each strip would not light. The strips were very well packed and there was no damage to the box in which the...

Either works fine. For a noob like me, parallel was easier for exploring design options. EB strips were my first venture into LED lighting. I had to order the strips and driver before I was exactly sure how many strips I would need, how to arrange them for an even spread and the current at...

My bad, I should have jumped in sooner. Sorry again. I use the EBs to grow orchids in a 24 sq ft area. They require much less light than cannibus. The screws are metal, but definitely a PITA to adjust. In my grow area, it is more convenient to have the dimming built in to a waterproof...

The constant voltage/constant current drivers are a better fit for EB (and Sammy) strips than the constant current drivers. At 700ma, the 560mm EB strips can accept voltage between 20.5v - 24.8V, well within the specs for this driver. They can also accept up to 1400ma of current, so there is...

The voltage you quoted is the input voltage (the voltage coming out of the wall socket). The output voltage over which that driver can maintain constant current is 107V ~ 215V, per the data sheet.

The F-series Gen3 includes parts that are made like a good dessert - double chips! They have 2 rows of diodes on each strip. There are double diode parts in both the 560 and 1120 mm sizes. The strips scale up proportionately, so the double-row, 1120 mm part has 4x the number of diodes and 4x...

I don't think you are stupid or wrong, but I'm a noob too, so I am comfortable being stupid or wrong right along with you. Reading through the data sheets, the F's have more diodes on board than the H's. For example, looking at the single-row, 560mm part in each series, the F56B has (8s x 9p...

Sure, PicklesRus, I’ll give it a shot. The Samsung F-Series Gen3 will be kick-ass parts for the amount of light they generate at high efficacy and low cost (on a lumens/$ basis). The cooler K-temp strips can generate more than 20,000 lumens/strip. At the soft side of the power range, they run...

Cost per strip is less for the M and H series, but look at cost per lumen: -----------------------------------M-Series---H-Series--F-Series Lumens @ max power-----3510----------4260-----19075 Cost/strip per Digikey--------9.93----------19.15----48.41...

Very interesting project. Where are you getting the LM561C strips? Perhaps another possibility for strips is the Samsung F-Series Gen3 (datasheet attached). Similar to the H-Series, these come in 1120mm and 560mm. The 2 interesting differences between the F- and H-Series is the higher power...
