Calculator says those vero B's are 2.4 umol/J 3000K puts out 169.7 PPF @ 1400mA . So 9 x 169.7 = 1527.3 PPF Total for the grow space. To convert it to PPFD you have to divided it by square meters so a 4x4 is 1.48 meters squared so 1527.3 / 1.48 = 1031.95 PPFD . Only thing I don't know is...

You got to watch out in here pretty much everyone measures the input side and doesn't factor in the efficiency, so they usually say they put out more then they are rated for when meanwell clearly rates them on the output side. Wattometers work on the AC input side and that's what pretty much...

240 watts

The front view shows the AC input on the bottom right hand corner flip the PCB over and it goes to the top right hand corner. So he didn't switch them around just have to account for the board being flipped over.

Shorted to ground or neutral , AC looks to be in the right spot. All it can be really testing with a ohm meter before plugging it in would have shown the short.

LOL lots of beer and a kiddy pool might have been used looks too big to fit in a normal sized bath tub. I went to the actual web site and he says something about LOL it is only waterproof on the front or light emitting side the side with he wires might leak a little bit LOL. Dudes making some...

Well at least you Edited the post I didn't want to tell you to read the thread to answer your questions since you are the far red guru lol. But yeah troll on better luck next time.

Thanks, yeah I machined everything for the fixture they get cut then painted flat white right away before the aluminum oxidizes. I designed the fixture to last a life time so unfortunately anodizing would look like hell in about 20 or so years after it gets all scratched up. #2 steel wool a bit...

lol If you read it twice then why ask me to read it you should beable to quote my posts in the thread lol and obviously come to the conclusion I have read the thread since I have posts in it. lol

Fused and switched ac input, built in timer ,Built in watt meter , PWM dimming + resistance dimming < switchable between the two, Built for a 3x3 and uses 2 cobs per a square foot ,The watt meter and timer and be switched out to Sonoffs to get the pretty much the same features and makes it...

Give to someone that needs your help I sure as hell don't ! For the second one thats a matter of opinion. The far red thread proves nothing really unless there is some peer reviewed science you want to show me that is newer then what I have read that is in there. Kinda doubt that but yeah if...

WhY would I ? If you look into the science what I said is correct only takes one pulse to put plants to sleep.

Yeah I don't know why people seem to get upset when you show them science that they are using more light then needed. I dont know why the only thing it would do is save them money on the electric bill. But yeah you are already invested in a light now plus you can just slap newer more efficient...

I dreamed this one up finally got it out of my head and into the real world.

Might not want to know this but this is how long it takes for the far red to initiate sleep in plants. After lights out a one second pulse of far red will put MJ to sleep as long as there is little to none far red in your regular grow lights. So if you have some 90 Cri lights you wasted you...

Yeah they will for sure replace a HID and grow the same if not better. Find some journals with people using the HLG 550 v2 and see for yourself. Not only will you save on light wattage but you also have figure in AC load. Alibaba is just like ebay so all kinda of different sellers some...

Thanks , I did that already, out of high school I went to work in a machine shop making parts for the space shuttle and back then we still had F-14s in service made replacement parts for those. We even had a top secret room where only machinist with security clearance could go work. But these...

Check out this bad boy out you can flower a 4x4 with almost 3 times the amount of watts as some quality LED. They been out for awhile but most have a 80 to 90 lpw rating. So I would say that it makes a better heater then it does a grow light...

Holly shit they finally kicked uncle buck to the curb. You can search is name in the forum and all the comes up is when people quoted him. LoL they deleted all his posts... But yeah just a very demented trouble maker that was here to stir the pot rather then try to learn or teach. AKA forum...

lol Dude you couldn't even smell the truth if it sat on your face and farted directly into your nostrils...! But hey congrats you can go play with uncle bucky also lol.
