well STRANGER proove it

u talk tyhe talk now lets see u walk the walk,,,,,,,,,,,,,,,,,which i doubt ur one of these who thinks he knows everything but knows fuck all no doubt +rep for that lol

Look up lumen versus lux. Lumen is the measure from a source, lux is the measure of light in an area. Lux adds just like ft candles.

iv used cfls alot and i think your wrong, 2 x 125w cfls are alot better than 1 125w cfl

What!! Ok put the spliff down:lol:! You asked if using 1x125watt cfl was better than using 5x25watt cfls. The answer to that is yes. You said nothing about using 2x125 watt cfls. ?????

i am confused, so why is more lights better? or is it?, im running 2x 1000watt hps.
will i get more with more light? what if i added another 1k watt MH? [video=youtube;u4Yh6Dkz0t4]http://www.youtube.com/watch?v=u4Yh6Dkz0t4[/video]
skip ahead to 48 seconds to see lights

lol true true but still there the same lumen output about 8500, the 2 would come to 17000 so how would a single 250w be better?

i get it now the higher the watt of the bulb the more lumen output,, and spencer use the mh to veg some more dude

Either way, plants arent sitting in the bulb, the light spreads out to the plants. We are going per lumens per sq foot.

in your room, More lights will = more lumens per sq foot. period.

with cfls you need them close to your plants so i would break the watts down to a few bulbs instead tbh and get them around the whole plant not just the top

Lumens, schmumens. This is silly-talk.

Yeah, in terms of light intensity measured at the SOURCE, two, ten or one hundred 26 watt bulbs next aren't any brighter than one. But SO WHAT? That's really NOT what's important to growing.

What matters isn't the intensity of the light measured at its source. If you're trying to grow plants what matters is the total quantity of photosynthetically useful light hitting your plant(s).

If you've got ten 26 watt CFL bulbs then you're putting out ten times the total amount of light, and ten times the total amount of light energy, as one bulb. If stick a plant under your ten bulbs, it will be hit by ten times as many photons as one put under one bulb, and grow that much better.

So OF COURSE ten bulbs are going to massively outperform one bulb. This is so blindingly obvious to anyone who has actually tried to cultivate plants under artificial light, its frankly embarrassing to have to point it out here.

I mean if there is no difference between one bulb and twenty bulbs, then why do commercial growers fill gigantic warehouses full of 1000W HPS bulbs? Hell, why even use 1000W lights at all? Do these people. . .who make their living growing plants. . .NOT know what they are doing? If it doesn't matter if you have 1 bulb or 10,000 bulbs, why can't you grow 10 foot "trees" under one 26W CFL bulb?

Man your so dumb its funny!

The lumen (symbol: lm) is the SI derived unit of luminous flux, a measure of the total "amount" of visible light emitted by a source
A foot-candle (sometimes foot candle; abbreviated fc, lm/ft², or sometimes ft-c) is a non-SI unit of illuminance or light intensity widely used in photography, film, television, conservation lighting, and the lighting industry.

Thought u said Lumens werent measured in an amount.
Somebody is confused.

Yeah you are by the looks of it.!! Basically if a light bulb states that it has 1700 lumen output then thats all the light will produce no more than that. So i will repeat myself yet again -- if you have 10 of them bulbs you will have ten bulbs with an out put of 1700 lumens each NOT a combined lumen of 17000. What you have just copied and pasted with out understanding was, the way in which lumens are worked out for different bulbs!

Let me simplify it for you all even more - if you have 4 candles and Place each candle in a coner of one room- so thats 4 candles in four corners. Then light each candle, the candle will light up the corner only to the amount of light the candle is able to out put. You can put another candle ontop of that candle as it would go out, therefore you would have to put it next to the other candle this corner will still be getting the same intensity of light but it would be covering more of the corner than before. Try it and see. COMMON SENSE!
