I just got my packages from KB. Pretty solid on the packaging as well, better than my first shipment for sure. Building the fixture this weekend so hopefully I will have pics up Sunday or Monday and flip my babies to flower.

Yeah, I thought it was a weird client request, but people are going crazy tonight after I posted it locally.

its the pretty much the first info showing up when you open the samsung page.
LM301H | SAMSUNG LED | Samsung LED Global Website
Samsung LM301H - Mid Power LEDs. Find out more tech spec and documentation about LM301H in samsung LED global website
was just asking out, thought the info is more knowen.
edit:
from their press release
Samsung Sets New Photon Efficacy Level in White LED Packages for Indoor Farms | Samsung LED | Samsung LED Global Website
Samsung Electronics announced an industry-leading enhancement to its mid-power LED package – the LM301H – for horticulture applications, such as greenhouse and vertical farming*. At 3.10 micromoles per joule (μmol/J), the newly introduced LM301H now features the highest photon efficacy** among...
"Furthermore, thanks to Samsung’s advanced flip-chip design, the LM301H requires no wire bonding, which helps extend the packages’ performance and reliability. Titanium dioxide around the chip also ensures higher durability when exposed to agricultural chemicals. "
the chip flip design isnt new, or its used by the 301b also.
the titanium dioxide stated, i´ve never found in conjunction with the 301b.

Received my two qb288 from kingbrite, packaging was really good. I was worried because someone posted here that they barely wrapped the drivers and could have been damaged. I think they read this thread.

What do you guys think about running 3 or 4 of these in a 5x5? Would 3 be enough for the space or should i go with 4?

4 of them at 800w total should work nice, more symmetric than 3 and better spread

You were reading my mind about the spread. I have a 3x3 that I've done well with using 1 HLG. Thanks.

The 240 fixtures have power for a 4x2 but spread for a 3x2. Put them in a square, eachone doing a corner and part of a wall so each side is covered by the long end and the short end of a 240 unit. That way you avoid hotspotting and week corners. Does it make.sense? The 3' side of one 3x2 and the 2' side of another one for each 5' side.

Almost done! I’m going ice fishing tomorrow so between getting all my shit ready and building the light, I only managed to get the frame done and the boards wired up. The 730 strips will happen Monday. She’s looking fresh! I will post action pics Monday. The electrical tape on the drivers is only temporary lol. They’ll be bolted down.

Any way you could sketch this up in a drawing app? I'm having trouble visualizing what you're saying. I'm currently planning a 5x5 too so I'm trying to gather as many ideas as possible.

Sorry, on my phone so i cant. Just do this: take some squared paper and draw a 5x5 in squares, then fit in 4x 3x2 sections in the 5x5 with one empty square in the middle. You can only do it one way. The middle square will have enough from cross lighting and thus avoid a hotspot.

Have you tried it out for even light spread? Those middle boards may concentrate the light to the middle. But if you have separate drivers for the middle 2 you could manage this by dimming.
Looking good enjoy your fishing

Greengene's said that both diodes are exactly the same, including sulfurization. He just did a youtube tech talk yesterday.

Ahh I gotcha, I was way to tired when I first read that, lol.
There was an instructor that would leave a charged capacitor on every desk the first day of school. Someone always got an education.

I’m hoping to have my buddy come over with his par meter some time tomorrow or Tuesday. Anyone know of any places in Ontario, Canada that rent quantum meters?
Yeah that frame is definitely an open concept and a work in progress. I may even say fuck it and buy three more boards and heat sinks after my current run. Have 9 boards at 80w a price, 3 boards a driver. I’ll definitely be building this light up as time goes on.
Also HOLYFUCK! Kobe Bryant’s dead! And his kid. So brutal, he was a good dude. Lots of charity work and helping under privileged kids. As well as giving us all the confidence to sink that ball of paper in the trash can from 20 away by yelling “KOBE!” 2020 is fucked so far. Glad I got my shipment before this corona virus business.

Fuck I didn't even think about that shit. I was planning on making an order for my veg lights week. Are they not shipping out right now or something?
