This is for a 4x8, 6 bars of 3 so 9 per 4x4

I just purchased 18 of these engines for a 4x8 area

Again you are confusing photon output with wattage. I'll agree that yes you can increase photon volume this way, however it's not working like you think it is. If wattage = photon output then yeah, but no that's not the case. Even different hps bulbs of the same wattage rating can put out more...

You are lumping draw and output into one thing, but they are not even related. For the purposes of draw from a wall yes wattage is additive. In regards to output of light 2x 600w of light will never be the same output as 1x 1200w, yet will have the same draw. I'm very sorry if you don't grasp...

As always man you come through with the best answers. AWESOME data for me to learn from

To the dumb and misinformed perhaps it makes sense that everyone with an adverse opinion would have to be the same person. Its a conspiracy to make him look bad, duh

Visit my business Facebook page (not going plug my business here as I'm notnsire the rules of this forum). Pm me for a link. I've been working in electronics on a level you couldn't imagine for over 20 years and I am one of the highest rates and highest paid emergency breakfix technicians in...

The draw is additive the output is not is what I meant. Get cocky all you want but it's the truth. Doesn't matter how you want to spin it

Is far red slang for infrared

I would like to go 10/14 and increase my yield with IR

I just got 18 cxm22 3500k 90cri luminus cobs for a 4x8 area. What would you use in this space for a good IR source

I hope i didn't impulse buy something a lux meter could have told me for $100 less

For basic testing though any par meter surely beats a lux meter right even the $150 one

As I posted that I also read about how spectroradiometers are what read various colors. I wonder if it would be worth getting one

Nice does it allow you to see how different colors on your array are covering the canopy or is it like the lux meter where it gives a total reading of all light

So 100% positive now I'm going to be getting a setup of 18x cxm22 Cobs from MrCob to cover a 4x8 area. I am beside myself with excitement as this really gets my nerd up. But im going to be banging my head against the wall because I'm a measurement-aholic. Ive seen some posts how lux meters are...

Hah, that would explain why they look electroplated, because they are! Yeah man that's extremely inexpensive and I feel like it's a good alternative for a DIYer

Thank Yoda for all that non info

Absolutely, 1kw draw is 1kw draw no.matyer what that draw is running, but this guy jumped on here to slam someone by asserting a terribly innacurate assumption as scientific fact and went on to insult someone who actually puts insane time and effort into this field. I deal with people like Yoda...

The aluminum beams uses to frame buildings seem to me like a cheap way to frame bars. We used to just toss the scrapn in the dumpser. Stop by any commercial construction site and ask if you can dumpster dive, they usually don't mind if you don't look like some who's get hurt trying to climb in...
