Will 2 150watt lights= a 300watt light?

[tadaa]

Ok is having 2 150watt hps lights the same as a 300watt light? I'm assuming no, because they still wont' have the penetration of a 300watt light, am I correct?

But you will have a better spead of the lights though.

Lumens decrease by half every foot they travel. Usually smaller bulb sizes have more lumens per watt. The ballasts create heat and two ballasts create a bit more heat then one equal to the watts of the smaller two so they are about equal for effieceny I would say but can not say for sure. The light distribution would be more even with two but the spectrum would be more balanced with one due to a little things called photonreturn. Basically waves can cancel them selves in a way creating a different nanometer but I would not be to concerned with it unless the bulbs are side by side in the same reflecter. So basically I have no idea

Lumens decrease by half blah blah blah blah blah blah then some extra blah blah blah after a spectrum would blah blah.. So basically I have no idea

lmaaooooo

(2) 150w CFLs will give the power of (1) 300w CFL..
You'll have the same power, but easier maneuverability because the power is split into 2..

You have the same number of lumens with two 150w as you do with one 300w, but NOT the same light intensity. Light intensity is decreased with two 150s because the area of light emission is doubled.

It is generally better to have one 300w than two 150w. The increased light intensity will produce healthier plants.

oh, to answer your question directly, yes, you are correct.

two 150 watt bulbs at 16,000 lumens each does not add up to 32,000 lumens its still 16,000 just a much nicer spread of the light its like gas 2 gallons of 87 octane doesnt add to 174 octane its still 87 just more of it

here is somthing 4 u to have a better understanding of what the guys are saying

you are incorrect. Whether the amount of lumens is exactly doubled I am not sure since there are other offsetting variables that must be taken into account.

As a matter a fact one 150 watt bulb might not have nearly the same lumen output as a nother 150 watt bulb. Wattage is a measurment of heat emmittance and does not always correlate to the same amount of lumens from one bulb to the next.:thumbsup:

Also, your analogy about the ocatne of fuel is also incorrect. If that were the cas ethen I would have blown up my car a long time ago.
