I see what your looking at now, I thought you were referring to the light itself.In a way, but the interference pattern is how you tell the light is being pulsed.

Those lines tell you the light is going dark many times a second. It's why low frequency SQUARE WAVE ballasts boost the efficiency of 315W CMH lights, it has nothing to do with the lamps themselves.I see what your looking at now, I thought you were referring to the light itself.

Not sure what is the issue with that pic. Used my phone and never saw lines. Will test my Kung Pao driver this evening and let u know is if I see any lines.
And at about 184 lumens per watt!
1000 Watt HPS and MH. T8s in some veg. I have a 600 watt Mars Hydro which I may take apart. Emailed Stephen, the man never sleeps - he and Robin are good guys. I am going to start making the change over. I have a friend who wants to start spectrum first.
My goal is to phase out HPS by April at the latest. I have a few and they all need to go.
what would be the recommendation for a 4'x4'
what about coupling these with a 315 cmh, in a 20"x20" hood in the center of the 48"x48" tent
Depending on the meter and the frequency you are trying to measure. Most cheap meters aren't reliable on AC above 1000 Hz. My fluke at work was a true RMS and good to 10kc -3db. But it would be nice to see the signal with an oscilloscope. ymmvA multimeter can be attached to check DC of driver.
If set to AC setting the meter will read a very small or zero AC. DC is supposed to have 0 AC.
If DC is (dirty) then it will have a AC component and you can see that on multimeter set on voltmeter AC
I'm thinking 8 @ 80 w each and some height for spread.Ditch the cmh. 4-6 boards would cover 4x4 very well. 4 running @ 50watts each will stomp anything a cmh would do at 315 watts!

Wall wattage btw.I'm going to start with 4 @700ma also for about 80 watts. May try them at 100-110 watts so I'm waiting on the new heatsinks.
Got my boards yesterday, thank you NGL! Got my driver today. Now just need heatsinks!
This is pretty obviously 60Hz bleed thru, based on the interference pattern. It's about the same bandwidth as HID on mag ballasts.Depending on the meter and the frequency you are trying to measure.

Lol that replaces an HPS thouie bro!I'm thinking 8 @ 80 w each and some height for spread.
Got my math wrong; 8 boards at 80W each is a good 1kW replacement. In fact, it's what I'm running right now.The future is so bright you got to wear shades! I run 16 3590's now at ~700w in 15 sq ft. I love them. Wall watts at around 92% efficient. I'd like vertical like yours but I am limited in layout. Crappy state.
Quantum Silence here in the threadBefore I start shopping I would like to know what are the differences between Quantum and Vero29 v7? Why should I buy Quantum instead of Vero29 v7?
How high on the ceiling can this light be installed? Can 650watt light of this board be installed as the same high like a 1000 hps?
Thanks in advance
