Been emailing The Guy and, indeed, he said that he could do 90 CRI but it would have to be S3 bin.

Good to go. Just had to move some things around. RapidLED order is due to arrive today. Hoping to finish this tomorrow if I can get away with ignoring my wife for a while. We'll see how that goes.

Ran back downstairs and decided to take a light reading on the the four board Photon Fantom 3500k Sunboard setup running at 2100mA. I was using the Hydrofarm Quantum meter and now realize, after reading the forums more in depth, it's a pretty shitty meter. So take this for what it's worth. At...

Redid everything this morning. Looks much better and screwing things down firmed things up a bit. Using thicker aluminum angle would have helped things too. Appreciate the suggestions. I'm sure others who may attempt a build do too.

So just out of curiosity I turned off all my fans and turned up the pot to 100% and left it there an hour. These are running at 2100mA. I turned on the fan pulling heat from the top of the tent. Air comes in a cracked zipper at the bottom. I'll post a new temp reading in a bit. These...

Here's a pic of a previous build. They are going to fit fine I'm just going to need to fiddle with my placement of a few things. I've made two different 3x3 lights each with four boards so I do have some experience wiring them together. These boards don't require heat sinks. The LEDs are...

Good idea. Thought I could just set them on top and them slide them around for optimal coverage. I can just screw them to the bottom.

If I was to do this again I might use some steel bars or something to firm it up. It's kinda floppy.

Maybe someone can double check my math here but the board is 67 volts and I have a 1750mA driver. That works out to 67*1.75= 117.25 per board. That would make the entire light 938 watts if set to run full. So I have a couple options. I can turn it down to work in a 4x4 area. Or I could...

To answer a few questions. These are 80 CRI and I got the 3500K boards. I started putting the frame together and things were going well to start. Off to a good start. Decided to put the boards around the outside as a ring as suggested. Driver placement was a little tricky but I think I...

I currently have boards with similar spacing between the LEDs and so far none are needed. I keep a fan running on the plants placed in a way that it blows over the boards. There is a small fan at the top of the tent pulling warm air out. I keep the bottom of the tent cracked a bit and air...

If, and when, I do another order of the boards I have I'll send you one too.

Interested in seeing some evidence of that. Can you point me to a thread that shows that? I'd love to dig into that. Is there a way to verify the real thing? How would anyone really know that they got a real samsung diode?

We'll see but I plan on it covering a 4x4 area minimum. I currently have two 1000 watt HPS in my 4x8 tent. I plan on taking them out and putting this in the middle. I don't expect it to be able to reach the far ends. I have a Kill-A-Watt and a Par meter and I'll provide reading at different...

Another cool thing about this build. Each board is 168 square inches. Multiply that by eight boards = 1344 square inches of board covering the 4x4 area. 48x48=2304 square inches. So more than half of the 4x4 space will be have a LED Board right above it. Also, ordered four of the far red...

Hi, I call it a new board because i haven't seen any other posts about it and the manufacturer said I was the first to receive them and a few other people were sent samples. I found the name of the sales guy for the factory that built boards for all the other QB style boards available online (I...

So I dialed my light on the 2100ma light to 150 watts. The light is 12 from the top of the plants. I'm getting 250-300 ppfd in veg. FYI.

Don't have time for a proper PAR map right now. Hopefully I can get one this weekend. How's 200 PPFD for a 24 hour veg? Too much? Too little? Getting about 200 PPFD give or take at 14ish inches. HAve the lights dialed back some so I don't know exactly how much wattage it's pulling. Like I...

Remember...I'm a moron. What's a trace? What standards would HLG be aware of that the manufacturers of the boards wouldn't be hip to?
