CrunchNasty the real issue here is not the lights, its the "Rented Premises" this is how you will get caught.

Landlords will find excuses to enter your premises, just dropped by for a beer, need to paint/fix/repair basement sump pump, roof is leaking, yard needs weeding, I decided to list the property for sale, the list goes on.

Unless you like living dangerously, don't worry about the electrical ratings calculations (interesting), worry about the Landlord catching you !

Why don't you do what I did. I went out in life and got a job, worked my ass off for 20 + years, saved enough to by my OWN HOUSE, then contemplated growing a few plants for my personal requirments.

If you don't get the point then, I suppose it is pointless to continue.

You get more lumens per watt with a 1000 than a 600. It is cheaper to run a 600 but more lumens/watt for a 1000 = higher efficency.

Running a 1000w light for 12 hours will be 13kw/per day. at 10 cents /kw will cost $1.30 per day
actually closet king,
vapour and babylon by bus are correct. 600s are more efficient in both operating costs and lumens per watt. what follows are manufacturers specs on both followed by a breakdown of operating costs.

I'm glad I live where I live. My electric rate is $0.067 per KWH

3200watts plus fans and exhuast in flower cost me about $125.00 a month.
Ive got my 520watts( 400MH, and 6-20watt floru. ) and fans for veg. hooked up on water heater meter which is charged at $0.051 per KWH going 24/7 and that runs me about $27.00 .

It helps that I use 220v for all but fans.

It cost me about $32.00 per 1000watts HPS per month.

Mybeans, the specs you listed are the ratings of the bulbs themselves rated to the wattage of the bulb as it runs off the ballast. The actual power consumption of your lights is based on the amps used by the ballast not the wattage of the bulb as previously discussed. You pay for what the ballast consumes, not what the bulb generates. You get more lumens from the power you pay for with a 1000.

same holds true with your formula closetking

closet king, using your formula a 600 is still more efficient.

600: 5.7a x 120v =684w

1000: 9.5a x 120v =1140w

600: 90,000 lumens / 684w = 131.58 lpw

1000: 140,000 lumens / 1140w = 122.8 lpw

mea culpa,
I was basing my 600w calc on an older 600 a friend used to use, His pulled 6.2A. Transformer components have improved. And I'm using a 1000w hortilux which has 143K lumens.
Thanks for the clarification. 2 600's would be better than 1 1000
but may push a 15 A ckt a little close if not staggerd on.

Thumbs up no problem

my uncle is an electrician. he's the one that convinced me the 600's would be better for me. otherwise i would have never known.
the only drawback i've found is canopy penetration.
i used 8 air cooled 600s over a 12' x 6' on light rails to combat that problem. this lets me get them to within 8"of the canopy.

you were right on the older models though. they have definately come a long way in efficiency in the last few years.
