2-600's or 1000 hps

[HARDDON]

I would go with the 600's, if you get the Philips SON-T bulb you will get 92,000 lumens per bulb. 600's do have the most lumens per watt and do run a lot cooler then 1000w but you are going to pay a lot more for two 600's. with a 6X4 room that gives you 24 sqft, with a 1000W thats 41 watts per sqft. with two 600's its 50 watts per sqft. you want 45 to 65 watts per sqft to get the best results.

Trying to find you to discuss your theory of people who use lumens don't know what they are talking about.

Why do you refer to the watts as being more important than the lumens and why do you lumens matter not to plant life?

Where do you get this position?

I wanna learn.

Or 1 1000w HPS light 140,000 lumens with a light mover will give more lumens and better coverage then 2 600 (2) @ 92,000 lumens.

just to make the topic intresting

grrrrrrrrrrrrrr....

[Garden Knowm]

HPS 1000 Watt (140,000 Lumens),
HPS 600 Watt (92,000 Lumens), x's 2 = 184,000 lumes
HPS 400 Watt (50,000 Lumens),
HPS 250 Watt (27,500 Lumens),
HPS 150 Watt (16,000 Lumens),

but wait there is more.........

[Garden Knowm]

the 1000 watt bulb gives 140 lumens per watt

the 2-600's give 153.3333333333 lumens per watt...


600's seem to be the choice of 4 out of 5 growers with nice teeth...

Sorry dude but the math does not work like that. It power dude and power is log rhythmic not proportional. 92,000 is still 92,000 you can't add them up and say they share the same space thus give you double the results. 600w lights will still degrade just like any other bulb will. They still have the same par watt sorry but the math is solid and true.
You donâ??t need to move them and they will cover a good area and yes they put out less heat. If you deal with the heat the 140,000 lumens on a track mover is hard to beat.

To bad they flunked math class then.

Let me get this clear so even a moron like me understands....

If I have a 5,000 lumen bulb....@55W

and i have 10 of them............

I do not have 50,000 lumens.....

I still have only 5,000 lumens....

But I am now using 550W to produce 5,000 lumens?

Under this math, the more lights I place in there, the less lumens per watt i get?

This simply doesnt make sense....

I understand the lumen do not add up...but according to the scenario described.....my lumens are no higher than the single highest lumen output bulb?

Now what happens when I place these other 9 bulbs that dont add up in the lumen equation...say on the underside of the plant and on the sides.

Do the lumens count then?

I am totally confused....but I am not yet stoned either so that could explain why.

Thank you for th comrauderie in DUMB LAND hard on... I was getting lonley over here..

Ok zandor I have my my pen and paper.. let class begin

[HARDDON]

I have a real winter affliction of Seasonal Affective Disorder.

It was either Lithium or light therapy....I opted for the light therapy AND Lithium

This is how I got into lights to begin with, far prior to growing.

I bought a light unit from people who specialize in duplication of sunlight thru artificial light in wintertime. It is badly needed as sunlight produces Vitamins and stuff in the human...

I have a unit that diplaces 23,000 LUMENS at 2 feet. This is as advertised. They said yes, if I placed it within 1 foot from me, I would be getting 46,000 lumens.

The deal is, it has 5 bulbs. So, even if I took out 4 bulbs, I would still have 23,000 lumens at 2 feet or 46,000 lumens at one foot.

IS THIS CORRECT?

If yes, the light would be no where near the intensity of the 5 bulb setup.

So, at some point, I need to understand....since lumens are not summable in total concentrative levels, what is it that I am missing?

The total wattage?

Each bulb is 55W.....so @ 5 bulbs, being the WATTS ARE SUMMABLE I have 275W producing 23,000 lumens.

Each bulb is 55W.....so @ 1 bulb, I have 55W producing the same 23,000 lumens???

Since a WATT is a unit of energy USED and not energy emmitted or displaced....the more lights I use the lower the lumens I get per watt.

This doesn't add up.

You need the wattage to power the lumens.

Now we know that 2 600W HPS lights will light up an equal area far brighter than say a 1000W HPS....since we're talking lumens and thats a fixed 1 sq. ft. measurement....watt...er...what is it that results in higher light from the 2 600W HPS setup than the single 1000W HPS setup?

The 200Watts?

Well thats energy used not displaced.....so that cant be it.

What else is it?

[arathi]

Even still having 2 600watts is better than just 1 1000watt. You could use a 1:1 ratio MH to HPS and have your self set from veg to flower.
