What do you mean? seperate drivers = a little more heat? Here's be setup drawn out. Kinda shitty drawing but.. There's also small computer fans in between each wall to try to help keep both rooms same tent. This is the 2nd floor. Plasticed off at top of steps with a zipper doorway.
I think they are assuming that the Rw150 and the Rw75 might not use the same drivers.....someone has specs somewhere, or they can be contacted directly.
I honestly didn't even look at what lights were being compared. I just saw that the driver was missing from the efficiency/heat equation as it was posted.
Maybe you should pay attention when commenting^^^^
Yeah...............haven't put anyone on ignore since 2010, BUT I'm getting real close
I'm only on my cell phone and it's very difficult to read and post. My attention span is very short also I had a terrible brain injury a year ago. I'm trying to learn how to grow/ setup grow toom and also trying to figure out how to use this forum.Maybe you should pay attention when commenting^^^^
A RW75 is basically a RW150 cut in half and share the same parts........so I'll rephrase it for you
Same chips+same wattage+same driver(s)+same mcpcb+ same secondary PMMA lenses+ same 120mm fan(s)+ same quick connects+ same MA + same daisy chain plug+ same casing material + same fucking brass hanging loops==== SAME HEAT
OR for people with an attention span of a fungus gnat
2 RW75 ===HEAT=== 1 RW 150

My bad on that one, I made the false assumption that they were comparing two different lights. I would have made the same mistake anyway because I didn't know they actually use two drivers in the 150.
You will get debate on this. I think about 7500lm/sqft is optimal. Anything form 5000 to 8000 is where you want to be. (this is only applicable if you are looking at white leds/florescent/HPS/MH/CMH/... not red and blue sources.)
It depends on the light you're getting, how efficient it is. In your 5' tall space you're going to have to be concerned with the distance required between canopy and light. This can use a significant amount of your available height to grow.
5ft is boarder line. If you want to do longer veg cycles and totally fill that space listen to az2000. 3w chips only require 2-3" of spacing so you can maximize your space, but you can get the same yield with shorter grows with more plants. It's a personal decision that should be considered when picking your light.
The surface area of a light using 3w chips has to be larger than that of those using COBs, you can't fit as much in as small a space, so the beam is less intense at closer distances. The point is, if the light is emitted from multiple sources the light is safe for plants at closer range.
And the laws of physics.
Why do you keep coming back for more...The surface area of a light using 3w chips has to be larger than that of those using COBs, you can't fit as much in as small a space, so the beam is less intense at closer distances.

I'm not talking out my ass, I have very good experience in this area.
I don't give up to bullies that try to use deception to convince people they are right. I will continue to pop in and point out any falsies I see. If I see people trying to simplify it down to only one "good" or "right" option I will be chiming. I don't react emotionally to the attacks I just stick to the point and always tell you why I think what I think along with what I actually think. What someone thinks really doesn't matter much if they don't have good reason. That reason can be learned via education, experience, or if you are smart a logical extension of existing knowledge.
You realize the noon day sun averages 1990 µmols at the equator right? They can handle and love 2159, give it a try, I have my colas within 2" right now and they are pretty happy.
I had no idea...
So tell me again...
This is the definition of a troll...just fyi.
