Air cooled reflector testing with Digital footcandle meter

[VerdeHombre]

Wow!

Wow!

Bushdoctor not trying to say you're wrong but that seems impossible that the SS2 could have better light distribution than the Magnum XXXL. Could it be possible that the bulb used in the xxxl was weak? Did you try switching the bulbs between hoods.

Thanks for the testing!

I'm thinking bushdoctor didn't actually do the tests.
He also says he gets 1/2 pound from a grandaddy purple plant with 17 days veg...

As I will agree, there is a LOT of bad information on these forums. The SS2 and the magnum xxxl are made by the same company so there`s really no reason to lie. Dongle, since you are the resident polygraph expert, you must make decent money with that skill. Spend some ($120 for the SS2, $190 for the magnum xxxl and $59 for the sun guage) and prove me wrong. Be honest with your results. As for plant yields, I probably shouldn`t have posted those. I struggled with the GDP`s poor yields for 2 years before finally dialing it in. Obviously you`d be surprised what 100w per sq ft, proper pruning techniques, NUTRITION , co2 and stringent cutting selection can do for the Ken`s GDP...:smile:

You did the tests, right?
What is the problem?
Just share the numbers and grid points.

Throw in some pics of those 1/2 pound indoor gdp plants, too!

I see a couple types of peeps on-line - those who work and contribute and those who spend hours critiqing - with no contributions other than hearing themselves sound impotent.

kinda like this post, huh?

bd- grow some skin, the twerp obvisiously never looked at any of the data and work that has been done here.

unlike sex organs -when it comes to sealed light hoods, larger is not always better in performance and satisfaction.

Man I miss the old cannabis world site. Thank you pico for the time and effort you put into this thread. It`s all OPINIONS when it comes to these boards. Numbers or not. Any serious grower should buy the meter and see for themselves before commiting to the pricey "next best thing"...

 

[dongle69]

I don't know why you would go through all of that trouble to test the hoods and refuse to share the numbers with us.
Please just post the numbers for the good of the thread and the community.
Even though they couldn't be compared to Pico's and others, the comparison between the two hoods in your test would mean something.

Luvin my SS2's even corner to corner coverage ..

 

[moses224]

I just bought all SS2 thanks to this thread, Thanks for the work you put into it

Luvin my SS2's even corner to corner coverage ..

I was going to post the same thing. It really is a good reflector and in my growroom, it's mixed in with Cool Tubes and the difference is obvious. Ill probably upgrade my Tubes to SS2's next grow.

I'd really like to see someone compare the SS2 with the P.L. reflectors.
As of now, I'd put my money on the Deep reflector being better than the SS2.
Because of this thread, a lot of people are buying the SS2-but the P.L. Deep could be much better. The test needs to be done.

PL bowls aren't considered air-cooled reflectors. Their air-coolable model design is simply a cover over a bowl with a similar restrictive design as the original SuperSun.

Just out of curiosity why do people not like the wider hoods ... they are not as intense overall in the center, but isn't the light distribution more even overall better so you can have a more even canopy and the light lower, or are they just that much harder to air cool.

I grow over 4x4 tables, do you think the results would differ when considering a larger footprint with bigger bulbs

Typical wide hood. Kinda like the Sun System XXL, and the cool sun 6 inch that pico tested

I seem to like them better than the Daystars AC's ... are the SS2's that much better than the daystar's? they seem to me to be a similar design

The cool sun 6 inch wasn't that much less and I'm sure some of the wider hoods might be more reflective?
pico's #'s with the 3x3 and 600watt

Pico are you going to do the 1000W tests with the larger footprint?

 

[ddd]

The new design of the P.L. hoods do not seem restrictive at all. There's plenty of room for airflow with the 6" vents. I'd imagine they'd be cooler than the SS2's too.

Fuck me I just typed out a big response to this and it got deleted. Here is the basic summary.

The super sun 2 is putting out an average of 7.7% more light in the above comparison, so not exactly something to sneeze at.

Ok, so you are saying that the light levels are less coming off of the cool sun 6" all around, and that if you bring it closer to the plants it will give a better pattern than the SS2. I don't think I agree.

You can see from the cool sun 6" numbers that the light levels on the corners(1,4,13,16) are dropping of when lowering from 21" to 18". So we can only assume that the corners would lose even more light when the reflector was lowered again. This would give you a brighter hot spot and less intense corners, so less even light levels all around.

I was actually trying to figure out whats the deal with my hoods ...
since the daystar and ss2 look very similar and the cool sun 6 look very similar to my xtrasun

They daystars do look more intense but I have to have the hoods two feet plus above the plants, to get a good 4x4 footprint (and reduce light bleaching) ... while I can have the xtrasun's about 10 inches above the tops ...

basically I'm saying I have no clue on reflectors, but want to know if larger footprints and bigger bulbs make a difference in hood choices ...

 

[pico]

I can't get a good look inside the daystar from the pictures, but the angles look different than the SS2 and it uses a different sort of relflective material.

Here are some numbers with 1000w bulbs over a 4x4 comparing the SS2 and the xtrasun 6". These tests were done by darth vapor so I can't speak for the testing methods, but I am sure he tested similar to me. Also, you can not compare these numbers with my numbers as there are way too many variables, so please do not try.

Looks like SS2 averages 16.6% more light in those tests.

dam is there a better way to filter threads that i'm missing ... where is the old filter button
just searched through and got the results I expected ... "but the posts don't link to the correct pages bahhh"
The SS2 rocks
My daystars not only suck but have a bad footprint
At least I can keep the xtrasun closer than the daystars to make up allitle .. and the footprints better

looks like my 4 daystars have got to go sooon lol

also noticed the radiant 8 did almost as well as the ss2 so I guess reflective qualities and design are more important than reflector size.

from darthvapors data

 

[pico]

yeah, I miss the old filter button too.

Just be careful putting that extra sun too close. At 18" that hot spot is over 8000 lumens and that will probably do some light bleaching.

Damnit, now I am curious about the hot spot reducer thing I have. I might have to test that fucker out. NO GUARANTEES, but my interest is peaked at the moment. Wait, hold on, my light meter is on loan. Bad timing......

 

[Guest]

hmm I have the xtrasun closer than that ...
