Trying to find new lights

Ok so. I have 2x4x5 vivusun tent. I want to try some new lights out.
I am looking at Mars hydro 600w (2 of them)
Or Mars hydro 1000w just one of them.
I will only be doing autos.
so which would be better?
Power consumption, yeild,ect.

I feel like 2 600w would give more ultimately and use more power.
would the 1000w be good enough to still make fat dank nugs?

I am using vivusun 300w and some off brand that says 1000w on the ebay page but I'm pretty sure it's only 400. Or 800. Not sure but it's a cheap-o.

They are working ok but I'm using more power than I want to with the lights I'm using now.
Thanks for the help.
 
Hey there. I’ve always been under the impression two lights are always better than one big one. You’re getting two core coverage areas with high light intensity, vs just one hot zone.

I recently bought the TS600 from Mars. So far it’s been a great light and very efficient.

More lights at slightly lower watts spread out - definitely. What ever you go with a decent rule of thumb for your tent size is probably around 300 watts from the wall. My opinion on led brands:

#1 HLG - top of the line, worth every penny
#2 Spider Farmer - great bang for your buck
#3 marshydro - excellent budget light
#4 viparspectra (new 2020 model only) - runner up to Marshydro

Full Spectrum white beats blurple every time.
 
I think it all depends on what your trying to accomplish, and it depends a lot of factors.. like in your situation yes 2 600w leds would be better then 1 1000w but 1 1500 w led would be better then the 2 600w leds.. but mainly if the 1500w has a wide coverage
a large portion of the equation is what’s your needed coverage which you said was 2x4 which any 1000w light should be plenty.. 2 600w probably way more then enough.. I’d say if you plan on 2 600w lights you should up your tent to a 4x4 area
malaise my pick of lights would be
#1 1500 yehsence (newer light company but really good for its price range low noise , low heat, low price,
#2 viparspectra
#3 mars hydro
I based my pikes off of specs
I’ve personally used the yehsence and I just love them wont be switching anytime soon.
 
Welcome, Hobbit
Trying to figure out 'how much' light you need for a successful indoor grow is a vital component.
This where the efficiency of the fixture creates confusion. The plants don't give AF about watts, what they 'eat' are photons of useable light energy(PAR)
As long as you're able to supply enough food(PAR), the plant will thrive.
This is where a simple metric will get you in the ballpark.
50 watts(actual power consumed)/ sq ft of canopy for HID(HPS,CMH).
50 watts/ sq ft for older leds(blurples)-HPS and CMH are actually more efficient.
Now, this is where using current tech diodes offers a big jump in efficiency.
They will produce the same light levels running at 30 watts/ sq ft of canopy.
So, you have 8 sq ft of area to light.
400 actual watts of economy leds or hps
240 watts of current tech diodes like the lm301b

Gbauto said it better.. this is what I meant you need to figure out your needed coverage vs par requirements.. in general don’t look at the overall watts(600w) look at actual wattage the lm301b is a good one I just prefer my lights with built in fans but over all that’s why I went with a bigger single led because it had newer better tech in it yes it says 1500w but it’s actual watt is 285w one down side is when you get lights that powerful.. you might actually get a sun burn sitting below it trimming your leafs
 
Have you looked into 315 CMH lights? I just got one for about $170 (U.S.) on eBay. Hooked it up (it came with a bulb and everything) and love it so far. It's only been a few days but I already have a feeling it's going to improve my grows drastically. You could get one of those for your tent and it may work better and keep your temperature fairly low. I just thought I'd mention it. Picture is everything that was included.

I've steered away from active cooling. That's the only mechanical part of the fixture that's subject to wear and failure.
I find that designing a passive system to be able to operate within parameters in still air ensures that even if the circulation fan(s) in the grow fail, the light won't be damaged.
 
A 315CMH would rock that space. It's actually more efficient than economy led fixtures. Just make sure your ventilation/temp controls are good.
Edit: I just re-read that you have 5' of headroom. so it better be a vented fixture.
 
I love my Mars Hydros. I run the tws2000 with an sp600 on 2 corners & a 1000w blurple (150 actual) on the other 2 corners.
 
So my mars hydro ts1000 made some decent buds. Still not 2x4 flower coverage.
I'm thinking of spider farmer sf2000 or
quantum board with lm301h 3500k 600nm uv, ir 240w

Would the lm301h be better than lm301b?
my vivosun 300w (135w) works pretty good but not enough.
now I have 2, 2x4x5 tents
mars hydro ts1000 & vivosun 300w for one tent and a new light for the other tent
 
So many changes, when i first started yes it was 2 130watt draws from the wall was better than 1 do to spread. I'm not a light person as most you know so i reasearch what will work best within my budget like most folks i hope do. I have a 3x3x6 ft i'm looking at Maxsisun or a 315CMH still looking gotta talk to DingusKhan he's got that.

Yeah that's what I've been doing. I wanna spend no more than 4hundo.

I think im try and get a kit. It will be cheaper than sp2000.
something that at least pulls 240w
 
Ok so I have 4x4x7 tent now. I just ordered
hlg 550 v2 rspec (refurbished) 640$ on the hlg site.
im so excited. That's everyone for helping. Pushing me to learn what all this diodes and wattage stuff
