Don’t get ViparSpectra. They’re shit. Get COBs or QBs instead, if you want a premade fixture and already plan to spend that much money.
So when calculating overall wattage for led I should not be using what they’re equivalent hps is but what they actually draw to output? I was under the impressions that 6 400w leds would be considered 2400w not 1,200.
I unfortunately am not comfortable building my own led although I’ve seen some very successful setups doing so. My other option I was considering was 2 MIGRO 400s.
Dear csovfnst,
They have prefabricated fixtures, particularly at Timber.
I’m looking at those now. I guess I need to do more research on COBs and calculating wattage per sq ft as I don’t understand the price difference for what appears to be less wattage for double the price.
Thanks for the vote of confidence, i always enjoy research and learning but having no experience has prevented me from thinking its a viable option. I’ll look into it further and check out some diy kit packages. Thanks!
241w in a 4x2 two years ago.
The Wattage they say is false.. go over to the LED section of this forum for lots of great info.
Thank you very much for the info. I’m still pretty new to the LED world so I have a lot to learn. I will check out the led section and continue my research.
And I will just add that for a 4x8 you should be looking at about 2000w of HPS or blurple light (power draw from the wall) or about 1200w of quality COB, quantum or strips.. otherwise if you still decide to go with 6xvipar spectra 450w (about 200w actual) id put them all in a 4x4 tent or 5x5 if you really wanted to stretch a bit and you will get roughly the same yield as if you put it in a 4x8.. it will just be more work with more plants in a 4x8 so not worth it IMO unless you put more lights or use more efficient lights
For cheap LEDs the efficiency is not great so we can treat it with the same rule of thumb as HPS and say 50 true watts per square foot is around what you need. ( and I do think HPS outperforms cheap LEDs)
For a 4x8 2k in hps is a tad much. And will make heat like crazy. In a 4x8 I would run 12-1400 watts of led. I built my light for under 225 bucks total. It' 335 watts in a 2x4....
Can you explain the red Strip lighting? Beautiful flowers by the way.
They are blank 24inch pcb strips, custom made. With 120 leds on each strip. 60 of them are 660nm deep red and 60 of them are 660nm HE photo red. Alternated so the reds mix together. And then I put them inbetween the samsungs strips driven on their own driver.
