1000w Versus 600w Hps

[aussie1]

Thinking about changing to 2 x 600w instead of 1 x 1000w HPS.

Has anyone got info about yields on the 2 different lights, how much difference in temps and humidity?

All opinions valued.Thanx

You'll probably get more lumens, and better coverage using the pair of 600's, but you'll get a higher temped hotspot for the single 1000w.

 

I'd say go with the 600's, start with one, and move up to two for the flowering.

 

600's are very efficient lights.

plus im sure your aware that 2 600 is a 1200 watt, compared to a 1000 watt it makes sense to yeild more out of the 600s. cause your using 200 watts more.

 

And like Luke pointed out, 2 600s have a better coverage.

 

only issue is its another plug, ballast.

 

ps- I use a 400 and a 600 and my 600 has to date given me more yeild than the 400, by roughly 2 ozs.

I always keep ballasts in the roof so heat from them is not a problem, but what about the temps of 2 x 600w compared to 1 x 1000w as in globes burning? Any ideas?

[Luke Skywalker]

1000's burn hotter, and you'll have to stage all of the grow around that one large, and very hot lamp.

 

600's produce a fair chunk of heat, and perhaps more than a single thousand if going up against two of em, but regular ventilation and you should be able to get more from the two, more efficient 600's than a single 1000, IMO.

with the use of light rails, there is no competition..only a fool would use a 1000

the best lumens for 1000 i know of is hortilux super hps 145000 lumens

 

the 600 i know of is philips son t plus hps 600 at 90 000 which is 10000 more lumens then the sunmaster cool delux 1000 metal halid which is 80000

 

anyways for me i go with the 1000 for this reason only power consumtion a standard 1000 runs at about 4 amps where a 600 runs at about 3 and a 400 2.2 amps

 

 

So heres my thing for 5000 watts of power id rather use 5 1000's at 20 amps then the 8 600's at 24 amps and its only 4800 watts.

 

Now i have a question that i really dont know the answer to .A house has 100amp line into it so there for using less amps would mean less of a power bill wouldnt it ??? also the 1000's in total only have a total of 5000 extra lumens on those figures.But the 600's have less lumens and chew more power.

 

Now on overgrow there is a tool that you can use where you can work out your power cost

My question is a 1000 watt light supposedly uses 1kw of power an hour and thats at 4 amps now this calculator doesnt ask if you use 400/600 or 1000 im guessing its totaled on amount of watts x cost per kilowat x amount of hours.

 

Does anyone else get where im going with this there for 4800 watts is 24amps using 600 but only 20 amps using 1000's grrrrrrr have i got it all wrong about the amperage being power used or should it just be total watts

[Discerning Grower]

yeah, your focusing on amps, you should be focusing on yield.

Why dont you use 5 X 700 with light rails...the you are only using 23 amps at 2750 watts.

Discerning Grower 5 x 700 ???? <<< whats that for whats the 700 represent.

 

Concentrating on amps sure but more lumens mean bigger yield.

I dont need light rails i use vertical lighting.

 

Plant numbers are a concern to me these days so id rather grow indoor trees

 

For a better idea of what im talking about look at this thread

Tartass, yes you should calculate your power usage by cost of power per Kw x watts per globe x hours used e.g.

 

1000w = 1Kw

average cost per Kw = 12c

bloom usage = 12 hrs per day

12c x 12 hrs = $1.44 per day

 

I think amps refers to how much grunt is in the line, not actually usage.

only a fool calls others a fool

Nice way to get bad info

 

Thanks to everyone (with the obvious exception) for input.
