Hi,
i bought 2x300 Watt LED cant wait to try them!!! Both Lights for 155€ good Decission to Buy these Lights?

Hi Andi
From what company are the lights. I think about to buy some LED in the next weeks but i dont know what brand o will try.

Salutations Andi,
Sorry as i can't answer your question and i've got more to add!
Could you describe please the lamp's global layout in terms of "nodes"? If you will...
The 5 Watts chip sounds like good news to me as that would promote reduction of this factor i just mentioned. As far as i'm concerned there can be just a handful nodes around 1 single plant less than 40 inches tall. How many of those LED chips i'd want for 1 individual plant? I dunno, yet at least i can argue it's more profitable to grow 2 plants instead of 1, or 3 instead of 2 - which was my plan until the hobby went to a stalled state. Anyway, when multiple plants are present their virtual cells share common sides between the nodes and hence using only 4 lamps, euh... I mean "nodes"... That means for a trio of 5 weeks old plants i'd need no more than 5 nodes to circle them at 1st, then once height has reached 2 feet or so some 2nd stage should be added, raising the amount to 10 nodes...
In my case no more than 4 hours of complementary artificial light was actually required as my sessions were supposed to finish on a window-sill, next to a rocking chair and vaporizer pipe. Etc.
Hummm... But there's a major difference between nodes that can move in 3D around plants compared to a pair of lamp fixtures. Maybe this has been discussed already elsewhere, have you considered using CFLs for side-illumination when the plants are tall? Also, i must mention i don't know what strain(s) is/are on your mind. At some time i thought 18" (dia.) was OKay for 1 plant, if i were to build a cabinet today i'd go for the full 2 feet i can use! Then i'd start reading about induction lamps (85 ~ 90 lm/Watt) with only 1 element, looking for a colder alternative.
In addition induction-light tubes can be manufactured which don't even have wires to fail... That last aspect might give them an edge actually (100000 Hours MTBF), once the technology has been standardized and matured. Then, heat... Etc. Oh my, enjoy the ride! This is a wonderful hobby with plenty of dimensions to explore!
Well i simply hope you get a fair answer to your initial question since i'm curious to read about it myself!...
Good day, have fun!!

Oh sorry i mean the Mars Hydro i bought on eBay from the MarsHydro Seller.
Hi again Andy,
Hummm... And the title was saying « ...60x5... », oh my oh my!...
Obviously i wasn't paying sufficient attention, my appologies and i wish you luck with this important purchase.
Please keep us posted!
Nice day, have fun!!

Hi Andi
Thanks for the info, good luck for your next grow. I will take a look at your journal to see what you get from your lights and who they work.
Happy growing cu tobe
Sadly the "NEW" MarsHydro 300w old model LED are nothing like the "OLD" old model 300w fixture. MarsHydro is using the 300w fixture for their eBay price wars and they took a big step back in quality and performance. I was told by a MarsHydro rep on another forum NOT to buy them!!!!! The "OLD" old model 300w fixture used about 180 real wattage the "New" old model is a wimpy 125 real wattage! I really like my "OLD" 300w old model fixtures and am glad I got 1 of the last to be sold before they made the change.
I am sure the "NEW" 300w fixture will work just fine. Just be aware they are lower power. I don't like hearing the factory rep say "do not buy them".

Salutations HotBunz,
What worries me is if it doesn't happen soon enough when it should have, with no inflence from factors external to the customer's own satisfaction, ideally - ref: Peter's syndrome (or some "promotion" thing), etc...
E.G. it must be about a natural tendency to protect credentials, reputation, credibility or whatever. At any cost.
Maybe the lower power consumption simply results from design rationalization, since it's been re-engineered as a function of i-commerce, if i understood this correctly. Maybe the old PSU modules or else were preliminary and hence somewhat wasteful, etc. Those are questions i suppose we'd all have wanted to ask this representative.
Hummm... The things money forces us to commit to!
Personally i don't feel much comforted having 120 copper traces/solder joints/pin-wires exposed to a hot damp room. If at least there were an exhaust duct with fresh/cool air admission... Or more possibly a couple water tubes exactly as in performing computers, whatnot! Air would just make sense as it's relatively harmless in a cultivation cabinet i guess. Lets hope no trade-offs were agreed on interconnections reliability as i count 120+ opportunities for Murphy's law(s) to apply!
M'well, please have mercy and just tell me there's a nice ending to this new story!
