When you move closer you lose light spread... Still not making a valid point. If 500 isn't enough to grow then a cmh has a 2x2 flowering footprint
Core coverage on cmh is about 3x3 max, 2x2 cmh coverage is beastly. You gotta realize when the light is lower than 24 inches those numbers go up significantly. This guy tested his light at 12 inches, if he put his at 24 inches his numbers would go down significantly.

Question:
Hi, what is the footprint of this reflector?

Answers:

  • The Phantom 315w Ceramic Metal Halide (CMH) reflector coverage area is about 4' x 4' during vegetative growth, and 3' x 3' for flowering phases. This is if this is your sole/primary light source. This light could even be used in a space as small as 2' x 2' comfortably. The 4' x 4' and 3' x 3' are more of a maximum footprint. Often these CMH lamps are used in between larger more powerful lights to give a better well-rounded spectrum since CMH's have such a wider spectral offering than traditional HPS and MH lamps.

If you are here to argue with me i'm not gonna keep on back and forth, either start showing some sources and have something intelligent to say or get ignored.

Wouldn't the cmh lower then 24" cook the beejeezus out of your plants?
And didn't he say that these strips could be 4-6" away? So why would he use them at 24"
Seems like your obviously a cmh guy and just trying to pick away at irrelevant details.
How bout we wait and see how these things grow plants before you slag them and are proven wrong similar to the beginning of the quantum thread.

Why does distance from canopy matter? If you look at an actual par map outside of a 2x2 the cmh has less par. Everyone seems to want to raise led up to hps height idk why you would do that. Led gives more usable light per watt that is a fact hps will not beat led watt for watt. If you want to argue the fact that led costs more money that's fine but hps does not provide more par per watt. I don't need sources your sources prove my point if you actually read them. For the record half my grow is cmh i love them but the Samsung diodes give more light that's a fact. You are also comparing a light with a reflector to a light without one add lenses to the led you get more penetration. Your not completely wrong your just making a very unfair comparison

i just dont understand the excitement for an item that produces about 2500 lumens/meter, and then need to wire a whole case of strips to sheet/pieces of aluminum. and then keep it 5" from the canopy to use the light. lipstick on a pig here. cobs and qb's have made this tech irrelevant.

I wasn't aware of any excitement just another diy build. These types of builds are the reason we have the qb and all the cob options that we now have everyone should be thanking sativa not coming in an saying how much better hps is without saying anything constructive.

His strips do 12,370 lm per strip 0r 10,570 lm per meter.

They also are spread out farther than a qb or cob.

I dont think you need a heat sink with a 2 mm aluminum backing on it. They are running about 55%.

Qb "tech" is Samsung diodes on a pcb this is Samsung diodes on a pcb...I guess I fail to see a difference besides layout

The layout is the difference. The QB and cobs are much more point loaded than these are. Strips allow for a more even canopy by spreading the diodes out more. And QB are more spread out than cobs.

I like strips better than cobs or QBs at this point. I have not tried the QB or the strips but will be trying the strips soon. But I like the idea of using a strip like this for a 4 foot wire shelf with clones on it. The strip has less diodes than the QB and is easier to spread on a shelf.

This is just another option than just cobs or QB. Both are good but need to fit your grow as does a strip.

I need to mention that these numbers are if this strip is run at 70 watts.

People need to do the math.....
I mean 70 watts to 315..
The savings alone for electricity means some thing the fact you can have these touching your plants just about can you do that with a HPS,MH or a 315 light?
I love HPS but the heat they produce in a country where my summers are sometimes in the 40 plus mark are just bout to come by there used by date..
And QB are just a bigger version of strips to say there not is beyond a joke...

I hope you dont think I believe that the QB is anything other than a bigger version of the strip. They are the same thing just different shape and size and number of diodes.

HPS has its place as does LEDs. HPS is great in cold areas but not so much in hot areas. I get some great HPS runs in the winter. I blow air that is down to 20 degrees below into my grow for cooling and CO2. But in the summer I struggle with heat and lack of CO2 from the same bulbs. My grow is just difficult to seal and adding CO2 would cost a fortune in the summer on top of cooling cost.

My point is different grows need different equipment.

He said his fixture pulls 600w...

here the second one..3ft x 4ft x15 70 w samsung 561c s6 aluminum strips
so...1050 w driven at 600w ..
interested to see the parmeter difference between this and the same wattage one above View attachment 3956723

im in 600w cob/qb camp all day. shit, id take 600w of viparspectra or roleadro over these strips
You think 600w of quantum board beats 600w of the same diode just spread how ever you want?

You're confused

Personally I'd take 400w of strips and 200w of cobs between the strips, you can't put a cob in the middle of your options.. Again light coverage wins

great discussion ...the only thing i am trying to do is show how these work..

they do not blast out photons like concentrated panels or cobs..but at distances from canopy similar to expensive retail multi bar units

They do allow for a very even coverage over a decent area with [apparently] no need for extra cooling because of the 2mm pcb's

and again..i am nobody special, we will see how they do at 6" because the readings at 12" were encouraging enough for me

are we arguing about which Samsung layout is better now? The Samsung S6 bin diode is the same whether mounted on a QB, ChilledLed, Strip, etc. it is still a Samsung diode, that works the exacvt same. The only difference is whether you are trying to help sell one product over another. I think there are more sales people here than actual users any longer. They used to label folks as trolls when tehy go to someones thread and go off topic. when this was done to GG or GM everyone ran to their defense. Now that is the norm, TROLLING. Now folks act like trolls here as their agents. make things look real bad and folks do not look very nice any longer. Profits over people I guess is the attitude here, not helping one another any longer. Just arguments and angry people, with opinions and few facts, reminds me of Washington DC where I used to make a living making liars into honest men, by keeping the promises they made, but never intended to keep.
