LED vs. MH/HPS

At a pawn shop in my town there is a very nice led setup for $300, the same led setup thats at mighty grow for 550.

Can you veg and bud with led with the same or greater success?
 
What's the brand? Model? There's a lot of predatory LED brands out there. $300 could still be too expensive.

Im trying to remember. Im goona do some research on some grow sites and see if i can find the exact model.

Someone posted and recommended the exact one to me on this site a couple months back, it was about 500 dollars. I just cant remember where or the model.

That LED is ok, but not something I would recommend you spend your money on. If you want the best results you want to mix spectrums. Warm (HPS, 2700-3500k), Cool (MH, 5500-7000k), and UVB.

HPS (warm) can produce over 150 lm/watt
LED (warm/cool) can produce over 150 lm/watt
The LEDs you linked to are more like 100 lm/watt
MH (cool) can produce over 110 lm/watt
UVB Bulbs (not measurable in lumens, but effectively 95 lm/watt in T5,T8 or Tanning bulbs., size to 5w of 10% per sqft)

If I were setting up a system new today I would probably go with HPS/MH sytems + 6500k LEDs + Tanning/Reptile bulbs. LED has a significant advantage on cool colors, but no/little advantage on warm colors...
 
HTG doesn't have a good reputation (with LED at least). Those lights use epiwhatever diodes which aren't very efficient, generate a lot of heat. Each round module has 15 3w LEDs. So, a 4-spot will be rated for 180w, but will draw about 120w. You can extrapolate that into the fixture you're looking at (the number of spots it has).

I bought a new one of those direct from China for $150 free shipping. It was a 4-spot with custom spectrum. It grows ok but generates a lot of heat. I would have been better off buying an Area51 RW-75 for $220. It runs with 45 less watts and grows as well, less heat (because it uses better diodes).

In essence, for $300 you could buy an 8-spot direct from China (with custom spectrum). For $440 you could buy an A51 RW-150 and it will grow as well (with fewer watts). You'll get a lifetime warranty as well.

So, $300 for a used one sounds high. These epi-whatever lights don't last a long time. So, I'd be nervous buying a used one for any price. I don't think it's worth more than $150 used. I wouldn't give that much for it. But, that might be a fair price if someone weren't willing to pay for a longer-term investment.
 
Gotcha. Glad i asked before just buying. Im considering getting a 4 spot area 51. Would those have various spectrums? Or would i run the led with say a mh on veg or hps on bud?

I am planning for long term as well

You don't need any other lights if you go with the A-51's. They are very good panels and you will get nice buds-much better than any of the panels like the HTG. They use white LEDs so you don't need to worry about tweaking a spectrum.

And i could use that for veg as well as bud

Yes. When I emphasized custom spectrum, I was illustrating how I got that additional service for that price. A known spectrum that I chose, not an unknown one that you can't customize (HTG).

The RW vegs and flowers well.
 
I veg and bud LED , but prefer using these when flowering.

These are medium priced panels ( Multi spectrum ) ..
I have done 6 grows so far with these , no problems.
They run like a champ.

Where do your numbers come from? @SupraSPL should come correct your dumbass on that bullshit chart. You know LITTLE TO NOTHING about LED technology....
 
LOL fair enough I run 5000K COBs at 227lm/W and building a new 3000K that will run at 191lm/W. On top of that, white LED lumens carry a lot more energy than HPS lumens. Not bragging or hating on HPS, just pointing out what is possible.

To answer your question OP, don't do it, 99.9% chance that LEd is a junker. You can get a 1000W HPS DE for $450.
