Hey man, just FYI, what you described is the total volume. Not area. Your area is actually 8x2 = 16 SQF., not 128... Also, just "600W of LED" could be really good or really bad depending on what LEDS those are so please be more specific. To light an area of 16 SQF you'd need around 1000 Watt...

14000 lux sounds a little low. The leaves also look very thin... What kind of lights are you using?

i'm so glad that you got it to work man, i felt so good inside when i saw your pictures! And thanks for the good wishes =] Here's a super cool tip too: In this configuration you can actually Dimm the lights by turning the potentiometer that's next to the green light on the driver. gotta use a...

Alright man, i'm going through a medical crises but i haven't forgotten about you. lets see if we can help you out... First of all, all of those connections are wrong. You will not be able to run the LEDS using that driver in that setup. Also most testers have a mode for DC testing and a mode...

What i do is i just wait until all the hairs are receded, the fattening stops and they get a golden shiny tint

My thoughts exactly. I built 4 grow lights using cobs. I'd replace every single one with strips if i hadn't spent the money already....

PPFD will be even depending on how you space them. You will have enough photons to not have to worry about any "penetration".... Strips rock!

Not really a problem, but would force you to use some sort of cooling for the strips. You can feel safe as long as you're not putting over 20W per 2ft strip. Exactly, you're correct! All you really need is a power cable, a PC power cable would work wonders since it already has the Line...

i can't answer your questions but i'm curious as to what the answers will be, in for the ride!

HPS are only better if the only factor you're considering is initial cost. But then your average 100$ 400W HPS output around 1 umol/j and today's latests LEDs are doing 2.5 umo/j without heatsinks... And will last for at least 10 years without needing any replacements...And we haven't even...

best of luck to you man

throat cancer? were you smoking cigarettes?

I always wanted to build my own lights... And i was afraid of electricity and breaking my components or getting shocked. But my curiosity was so much that i took an electricity course just so i could start building my own LEDs and understand stuff like "series", or "parallel"... But actually...

My pleasure man, i really enjoy this =] The 2 footer strips that i recommended max out at about 20 Watts (19 volts * 1.05 amp) per strip when not using a heatsink... So if you were to use 6 with a 150W driver you'd be running them at 1.32 amps, and maybe cause some problems... The LRS-150-36...

Drive a LED is just special wording because some people call the the POWER SUPPLY a driver, it's just a wording difference. "Running" or "Driving" or "Powering" an LED all mean the same thing. Usually what happens is that the LED will be run at the maximum power the power supply can output...

interesting!

The 1 foot figure is accurate, but the others past that point are only estimates! In reality, you should be getting much more light that those distances... We've seen many posts here where we actually find that we get much more light in lower locations than we what we calculated.

You'd be surprised, i think you're en route to get a pretty good result once you add the 150W worth of cobs. I say try to distribute the light equally, and leave the purple panel in the center, just try to have it be as even as possible. If you got yourself another one of those 75W cob...

Hope this helps your cause: For 7.750016sqf, used for 18.0 Hours a day, using 4.0 LEDS running at 50.4 watts with an efficacy of 2.25 pf TOTAL LED PPF output of 453.59999999999997 μmol/m^2/s in a space of 7.750016 ft^2 or 0.719999736448 m^2. Daily Light Integral (DLI) @ 1ft = 41 mol. Totaling...
