I don‘t have the knowledge, but I think, this is a parallel circuit, running the strips at around 200ma. I guess because it‘s cold, and maybe some other factors (choosing max voltage rating) they need more than the rated 42v (at 50C). In addition the A driver can put out more power than rated. This is the only way, I come near the 67w draw:

50v * 200ma = 10w * 6 strips = 60w + driver loss = 67w

its wired in series in first pic

Sorry, but his is bullshit! Neither the picture shows a series wiring, nor the draw would prove this...

Every + and + is connected, and every - with -. How a proper series wiring should look like, I just mentioned.

hey guys any help would b appreciated, hooked up 6 x 1120mm bridgelux eb strips on 1 x meanwell HLG-320H-c1050a wired in SERIES, fired them up at 50% on the driver then turned up to 100% looked pretty bright I plugged it into a kill a watt meter and only got 66.9watt and 0.57 amps , shouldn't this setup be running at 300w ? I don't have the best understanding of how these work but had a licensed electrician help me hook them up.

@chinakush
What you did is parallel wiring if you use all 4 connectors.
You need only two connectors and one wire for series connection.
Driver goes to a positive connector of the first strip,
a 2nd wire goes from negative to positive of the next strip and
the 3rd wire from negative to the 3rd strip and so on....
The last negative is conncted to the drivers negative pole and thats it.

Sorry to upset you, but they will be send on 12/19/17 from bridgelux to digikey. Delivery time 4-6 days (so the earliest date would be 23 a saturday). So digikey themself won‘t have them before 12/27/17. Thats what I know.

I cant understand how much is the max lm/watt ratio (to be compared with Samsung hard strips).

1 more question, 2 ft strip 3000k, unit price of 7usd is for 200pcs order?

2ft. strips:
EB-Series gen.2, 175lm/w, @700mA, 13,65w, (7s8p, 87,5mA per diode),
H-Series, 180lm/w, @480mA, 10,8w, (8s6p, 80mA per diode),
F-Series, 168lm/w, @1120mA, 25,75w (8s9p, 124mA per diode),

F-Series, dimmed, 181lm/w @700mA, 15,75w, (77,7mA per diode)

thank u dood and everybody else who responded with help!, will get this fixed right up and update! I was just thinking damn I only had them at 67 watts full power and i thought they were pretty bright already i cant wait to see the full 300w ... also ordered a bunch of gen2s cant wait!
