600w vs 1000W

Hello group. I'm happy to have found this forum.

I've heard that running a 600w digital actually is more effecient than a 1000w.

Is this the case. The logic is that the 600w runs cooler so does not require the height clearance the 1000w does. As a result of the light being closer to the plant it will receive more lumens as the lumens dicipate with clearance.

So would a room be better off with 1000w or double the number of 600's????

whatcha all think?

Theres many threads debating this so a search will give you all the answers you need but my personal preference is the 600s.

Same here, I have battled this same question and went with the 6's.

cool thankx guyz. my gears have been grindin and it all makes sense. i have thowies now and deep down i can feel how its right as i know my current limits yet it still seemed like a step backwards.

Ya I'm 2 weeks into flower and I can say "So far, so good".
I have my 1000w on standby as well, but I don't think I'll need them.

From what i read in a light thread somewhere 600 is the most effecient but i cant remember if they included 1000's, one book says 22000 lumes at 2ft 600 hps, 35000 lumes at 2ft for the 1000 hps, 12500 lumes at 2ft for a 400 hps. I would go 2 600's lol if i only could dream because you could lap over and have much more growing space from what i've read no real life experience

Hey Sureshot, can ya keep me posted. I'd be curious to know how they finish or an update in 4 weeks or so. I think i might hit one more harvest and then purchase as they arent much cheaper than the 1000's. Its a lotta extra cost. thx

M blaze, are you growin with 600's? if so how many. do ya still need 2 per 4'sqd or do you just spread them out evenly?

thx

Yeah I got 4 x 600s but I dont know how many squares they cover coz ive never even measured my room lol.

1000w
pros - more lumens, more wattage in less units, more intense light + penetration
cons - heat output

600w
pros - highly efficient for its class, allows wattage to be distributed better across multiple units
cons - cost/watt ratio exceeds that of the 1000w

Are you saying that a 1000 watt light is cheaper to run than 600?

600 or 1000.....

There is not a one size fits all answer here. It really depends on each individual set up (grow room).

Examples: If you are growing in a confined space (closet, cabinet, fridge, etc) where height, heat, etc, etc are an issue then a 600 would be a better choice and give you better results with less hassles. If you are growing in a large area where height, heat, etc, etc are not issues then a 1000 is going to give you better results. It is all about each individual set up.

no it costs more to run a 1,000 w

I'm saying when you purchase your ballast and accessories from the store, you are spending more $/watt in the system for 600w.

1000w offers 166% of the wattage available in a 600w and costs 10-15% more.

or maybe you can think 600w is 60% of a 1000w for 10-15% less retail cost.

regardless of the energy consumption figures I'm just speaking about straight up retail merchandise in terms of its output, I mean buying 5x600w for 3kw of light is more expensive than 3x1,000w for 3kw of light. especially because you need 5 reflectors instead of 3, 5 bulbs instead of 3, etc.
