Best Top of Line LED For 4x4 or 5x5?

[MIGrampaUSA]

I’m also using aluminum extrusion for this full build. It has T-slots on each side and flat on one side so I can attach the strips. The pic is basically what I’m getting for my frame except for one side will be flat with no T-slotView attachment 1155694

I'm very familiar with the material. I have my hands on it almost daily. The brand we use at work to build mainly machine guarding is 80/20.

I think I have it figured out. This is what I put together.

I need to think on it a day or 2 before I pull the trigger.

I opted for the red booster that has less diodes but has the same specs as my PLC photo boost strips so I can easily wired them all in series together instead of sets of series/parallel wiring and I can follow the PLC YouTube video step by step still since I’m a newb at LED builds. Atleast that’s what I was told… nice choice if your making a flower supplemental fixture.

You are going to get a lot of opinions as this is a polarized topic. I decided on LED vs HPS because of the tradeoff. If electricity was free I would go HPS but since its not I went with LED. I did a lot of research before I bought a light and decided on the Gavita 1700e. I couldn't be happier.

Already stated it.. same boards, same diodes, same driver.. what else is there that can differ? basically same umols too. but for half the price, thats why stay far away from hlg.

I'd really like to see the said lights tested by this guy: https://ppfdcharts.com/
I tend to doubt they will stand up even the SFs didn't (though only the 1000 is listed, he did test the 4000).

Spider farmer 2000 weeeeewwwwww

Fuck the world

I recently swapped out my 2 SF2000 with a HLG Scorpion Rspec a quick phone check showed the difference so weeeeewwwwww on me.

Rail style LED's are the future and I misspoke about UV as I wanted to say or write IR, my Viparspectra 450 w have 4 IR diodes each, carry on I want a better light soon.

The other factor as we know even the best product can go bad. Maybe a manufacturers defect or what ever. These lights aren't cheap so if they went bad would the seller fix it for you? Suppose a few weeks into using it the driver takes a dump. Drivers aren't cheap for these big lights, you call or email the seller and they hem and haw. If you don't have a another light to stick on your plants your going to lose the grow. Some of these people put all kinds of glowing stuff on their website about how they promise to take care of issues, but will they? I've had one screw me on a couple $20 fans, I would not buy a $1000 light from people like that.

Yes, I want to add more red, IR and my E720 doesn't have any UV. I've got 3 burple 4' T8 style LEDs providing that extra color now but, correct me if I'm wrong, I believe the strips would be an upgrade over what I've been using.

Thanks man I appreciate that. I actually purchased the Scorpion Diablo board its incredible. Im on my second run right now. It makes nugs so dense you could shoot them in a slighshot and break a window. Epic flower! This was from my first run Lemon Wookie Glue...

the lights all work, the diodes are all about the same. brand wise people picked samsung, but many are as good and some better. the driver is worth note, it is among the better ones, but again, others are as good and there are better.

my opinion is the control is where the money should go.

since it is diodes, you can control each individually. you could do so much more with a system that could dim or brighten any spot, or section as needed. set up some array tracing and some radar and you could almost automatically have the right light at the right time in the right amount, you could set a daily allowance and adjust for best penetration. no reason it cant all work with integrated sensors and plotting software add in lidar and omg youd have a set up!

it seems simple electronically. ive seen one company doing it.

no matter how good the light is, with control you can make it much much better. and when you start doing that you will see the reason i like the driver and say the diodes are all about the same!

So what are your thoughts on the rayonled 720 UV or the california lightworks solar extreme 1100uvb?

 

[RigRoss]

Yeah those things are sexy. Out of my budget though.

I landed on 2x SpiderFarmer SF4000 or 2x Growers Choice ROI- E420 ... Both are around 600$-ish

The ROI-E420 loses almost 50% of light output after 4000 hours of use but still pulls the same amount of power from the wall.
