Those do not seem to be the best selection of strips. There are less expensive with more lumens that these strips. You are likely paying more and getting less lumens. You should also consider something like either Bridgelux Gen2 BXEB-L0280Z-30E1000-C-B3 or Samsung F-Series SI-B8V261280WW. Why...

Fuck off, I do not troll. Everything I said I believe to be fact and if you cared enough you could confim waht I said on your own, It's fucking rude to call someone a troll based on jack shit. Why did you find it necessary to be a fuckin' dick???????????? Goddamn sociopaths everywhere. I'm...

That is likely no longer true. What I am hearing from large scale growers is they have been moving away from HPS. Of course they are in competition and do not reveal what they are doing to their competitors. Heliospectra is making inroads in cannabis. Everybody that has one loves them. I...

660nm is almost a good as 680 nm (ideal). There are no 680nm LEDs only 660. 450 + 660 is the standard most efficient wavelengths for photosynthesis. There is more to grow lights than just photosynthesis. There is a lot of interest in secondary metabolites (e.g. cannabionoids) These...

Does no one read? Kind K5 is not blue and red. If you want white crank up the green. Well if you use a Mars Hydro of course not. If you want top notch results you have to pay for it. It's pretty clear no one here wants to pay the price of admission they'd rather play with their child's...

Idiot. They use mostly Cree.

It is full spectrum. 12 different wavelengths all individually tuneable. The Kind is nothing like the cheap Chinese garbage. There is no proof in other threads. It does not exist. If mono LEDs were not more efficient than a phosphor pumped LED then why would they exist? You most...

Have you tried one? He said I could not say it was more efficient. Well I did. And it is true.

That's pretty fucking presumptuous. Add that to the list of your character defects. I do not hate you. I think you are a sociopath. I would refuse a drink if you offered one. I would not talk with you in person. You are repulsive. You have said some really fucked up things. Other...

Yes I can. The Kind K5 is more efficient than a CoB. Mono LEDs are intrinsically more efficient that a phosphor pumped LED. I totally agree. But if someone is considering a Kind you should not blindly say it is a bad decision. Especially when you have nothing to base it on. Kind is not a...

It's not a "burple". It has 12 programmable wavelengths. Burple? What are you 3? Is that a color in your crayon box? Get some big boy crayons with magenta instead of burple. New technology? Have you been living in a cave? CoBs are horrible IMO. What has changed in the past few years...

How do you arrive at that conclusion?

I would start with four, or twelve 11" Bridgelux Gen2 strips. 1, or 3 strips on each wall. Or four 22", one on each wall.

I would recommend making an 11'x11' fixture which would give you very good coverage over a 10'x10' area. Use between 60 and 78 44" Bridgelux Gen2 BXEB-L1120Z-30E4000-C-B3 Make the fixture with 20/26 rows of three 44" strips. Make the distance between rows all the same. Use one Mean Well HLG 185...

One of my clients is the University of Florida Horticulture Dept. and they like it. Keeping in mind they got a $500,000 grant to see if LED light could extend the shelf life of strawberries. They love their four $3,000 Heliospectra RX30 too. Whole different perspective.

The Kind is not that bad. This bestVA is beyond horrific. Send it back! You got robbed. This vendor is a liar and fraud. It is NOT 2000W, not even close. Probably less than a 100W HPS equivalent. If you do not send it back you flushed your money. If you own a drill and a hacksaw and know...

I did not see much in LED components, mostly chips. The 4 dice entertainment mix component was interesting. They did not publish thermal resistance. Forward voltages were a bit on the high side. No deep red.

They both kinda suck in my humble opinion. The Duris have a 6v forward voltage. I never liked the Sunplus 35 from the they were released. As I recall they were weak in efficacy and thermal resistance. Thermal resistance is high on my priorities when comparing LED characteristics.

Too many around here just live. I'm sure you know who those guys are.

I use Ki-Cad free open source to make strips. I just make the LED component footprint then wrote an app to place the LED footprints on the PCB. All the design files are text based so they're easy to create/edit with any programming language. I used a PHP to create the PCB. I just input the...
