1000 Watt Vs 600 Watt

Guest

I'm about to set up two new grows, and I've heard before that 600 watt bulbs rule over 1000 watt bulbs for efficency. They dont put out quite as many lumens as 1000w but are much cooler. My ? is are they worth having overall? I've grown for 7 years using only 1000w bulbs and they generate alot of heat but also generate alot of bud, so if anyone out there has used both and has a definate opinion about this subject let me know.

no contest in terms of efficency ,,,a 1k hps gives approximately 140,000 lumens which = 140 lumens per watt ,whereas a 600 hps gives ya 92,000 lumens which is approximately 153 lumens per watt ,,,
so best combination is 2x 600 hps to give 306 lumens per watt ,it may be an extra 200 watt but it smashes the 1k efficency by giving an extra 166 lumens per watt and an extra 42,000 lumens overall

i'd say theyll be more heat off the 2 1k's ,the light an heat with 3 x 600's will be spread more thus reducing overall temps ,i believe

I think overall the 600watters will give you your best par/watt rating-better in comparison to a 1000watter I believe. But like hazy said overall there aint no contest son, and why should there be-theres an extra 400watts. As far as light spread and intensity go, a 1000watter wins hands down.
Now 2 x 600's vs a 1000 watter is a different story-but so is the price. I had to buy 600's over 2 1ks and it stung mate. But your light spread is greater and if you can cool your 600's enough, maybe they could get close to the intensity of a 1000watter?

Different set-ups require different needs- I'm now in a new space and would gladly trade in the 600s for 2 1k's, but at the time 600's suited my requirements. I'd stick with the 1000watter personally, you say that temps can sometimes get out of control with a 1k-I'd stick with a 1k, sell some green and sort out your ventilation-then you've got a consistent envirorment for your 1000watter. You'd yield a few oz less with a 600-which would have payed for the vent upgrade.

Sorry that I'm not a user of both-can only comment on the 600's. Hope someone with a better answer helps you out buddy.
All the best

Thanks guys, I appreciate your input! Price might be an issue for the new rooms so i will prob. just stick with 3 1000watters for each room. But I might change my mind and go smaller on one of the setups and use a 3 600's just cuz i'm curious to see what they can do. thanks again

The draw back about 600 watters is the price of the bulbs. They can cost as much or More than a 1000. From my not so local hydro store -
600 Watt $99.95 1000 Watt $89.95 for a "Standard" HPS Bulb
Prices vary so shop selectively!

Is that because the 400's and 1000's are used for other application other than growing? Car-park light,street light etc. Then the 250's and 600's are mostly prduced for growing purpose.

Only reason I can think of......? (But that aint saying alot)

No clue as to why. I buy my 400 bulbs from an Electrical Supply House for $17.00 a pop but they do not carry 600s (special order only) so it may be a Less of a Demand thing like you said. Both 400s and 250s cost $39.95 from the hydro store. Thats better than a 100% price differential because they come from a Hydro Store. Fuck that! I used to run a 600 but it got wet and the ballast config was ruined and the bulb burst and now I am sad. I run a 400 now with good results but if ya want Pop Can sized colas go with the Bigger wattages.

in the uk on average rate of 8 p per kwh a 600 uses 58p an a 1000 uses 96p ,,,the answer to the initial question is 600's are a lot more efficent and definately worth having

Electric Prices vary from Area to Area but I'm guessing it's about $20 US a month. I am fortunate enough to have my electric Included in my rent so I haven't seen a Bill in quite some time.

This is a good topic & i have used both over the years. I prefer the 1k hortilux for my style; also the 600w hort. bulb cost the same. I like the 1k better not because of efficiency, but simply because i like growing large plants & the penatration it gives allows me to get solid buds 4-5ft down & the 600w does not compare in this catagory..imo. I suppose a good arguement could be had for every different situation/set-up as well as how large you want to grow your plants. Lastly you cannot really compare 2ks vs 3 600s. In that case the 600s would win hands down with a far better overall coverage. Is everyone confused now..lol. I sure am, but that goes without saying :pointlaug .

I believe 3 600s would generate less heat overall & in general they are concidered better lights for horticulture use. Mabey more should look at what plants they want to grow... a sativa lover like myself, i would suggest the 1ks for larger plants & those who want to grow squat indicas may fair best with 600s. Really they both do a great job & apply best in different situatios. yf3 :wave:

Which generates more heat 3 600 watters or 2 1000 watters?

Wattage is a measure of electricity used and since only so much light is actually produced: Watts = Heat

So two 1000 watt lamps will produce a little less heat than a ceramic space heater on low (1000 watts) and three 600 watt lamps will produce a little more than that same heater on the high setting (1500 watts).

So basically 3 unvented 600 watt lamps will produce more heat than 2 1000 watt lamps. BUT they do have more surface area (which is why shop lights feel cooler than standard bulbs of the same wattage), so with proper ventilation and a slight breeze blowing over the bulbs, you should be fine.

1k's are used more extensively in commercial applications (stadium lighting, street lamps etc), that is why they are generally cheaper. 600's are used in europe a lot to save power. Three 600's do have more coverage area, but less penetration than 2 1k's, so they are really great for sog and scrog, but not so much for trees.

I actually prefer the 600`s in my tree room over 1000`s, my first grow with this setup I was using all thousand watters and the yield was great, I sold all but two of the 1000`s watters and now I grow two groups of 4 plants with 5 plants per room 1000 in the middle and 600`s in the corners and my plants are doing just as good if not better.

on the other hand I was doing sog for a long time and I ran all horizontal 1000`s with reflectors with good yields and super dense buds, i think horizontal the 1000`s can`t be beat.
