Lumatek Zeus 600 Pro

Leds from Zeus 600w PRO are looking different than http://en.led-star.cn/product-show-2.html
You're right, good eye. Your leds have one corner on the negative side shaved off while this ledstar2835s at the Dongguan site have all the corners clipped.
So what are these bright bastards and how long will they last?
 
Yesterday Lumatek replied to my inquiry last week about who manufactures the leds in the zeus pro. The answer was they wouldn't say. Only this,
"LUMLED is our own brand of diodes. We decided against using Lumiled and developed with your factory new, highly efficient diodes with our own branding."
I wanted to find out who makes them and how many hours they run before getting down to say a lumen maintenance of 80 (LM80). Just have to hope they are as good as other name-brand diodes. Oh well, still hope to buy the Zeus 600w Pro to test.

They need to provide all the specs on these diodes if they want to be taken seriously in the commercial sector. Mystery components don't go over nearly as well these days.

It does seem strange they wouldnt offer more info on these diodes. I dont think I would spend a grand on a light without having more details.

Maybe they will offer a test report from a reputable Western test lab, at some date. More important are things like the output and efficiency, than actual identity of the diodes. And for the forward thinkers, true running temps, not some reading from a stabilised thermally controlled test chamber.

LM301 has become ubiquitous, its almost like people think theres only one way to skin a cat. That if a product doesn't have those it will not measure up.

Why is your growing space not a stable thermally controlled environment though?

The concern is how well a product is designed to sink and dissipate heat away from diodes.
Some buyers might be reassured if the led luminaire test reports provide datasheet-like detail on ramp-up and operating temperature parameters measured at the pcb level. Possibly in the form of a graph of time/temp.
I guess it can have implications for things like lifetime and efficiency of product.

I have seen people mention Lumen Maintenance. Makes sense, especially where a lot of hot little diodes are crammed tightly together. One product might perform this service better than another, but the consumer cannot be sure with ambiguous reports.
 
Yea you guys make some good points about the info given about the diodes.

Im not looking to spend that much on a light right now anyways. Next run will be my first time using leds and will be adding 2 spider farmer sf1000 to 2 315 cmh. If i like the results maybe Ill upgrade to something like the zeus in the future.

Technically you want stabilized operation performance specifications @ 25c ambient but you're correct many LEDs are tested at Tc 25c due to pulse measurements being a viable binning process.
If the led luminaire test reports provide datasheet-like detail on ramp-up and operating temperature parameters measured at the pcb level. Possibly in the form of a graph of time/temp.
Most LED manufacturers have simulators with Tj and Tc inputs. PPF and PPFD results should always be recorded at a stabilized operating temp when Ta = 25c
 
How are you gonna test it ?

With a light meter. Then will have to put it to work and see how long it lasts compared to the COB's and Quantum boards we now use. A few years back I used those cheap Chinese LED rigs with the cheap little drivers and fans drawing around 300 watts maybe. They grew about as good as HPS watt for watt but didn't last very long and trying to get warranty replacement parts was a freaking hassle. So this rig, with mystery chips and driver and a 5 year warranty promise, seems sketchy alright. Lumatek is not a new company so am hoping these Zeus pros hold up for a few years at least. Wonder also about the durability of the two prong connectors on each of the light bars that are magnetically held together to the frame. From the video they look like they'd be fighting gravity every second to stay connected. Just seems they should have been designed to snap in from the top instead of up from below the frame.

I still need to get 3 more lights to cover 240x240 cm . Will try one of those https://www.alibaba.com/product-det....41413.10.2a996f16248Dqq&fullFirstScreen=true and maybe 2-3 more zeus. Magnet is pretty strong, weight is on magnet and on the opposite site where is no connection and no magnet (contra).

Those pics are nice. Thank you dubstafari for reporting on your zeus. Please keep us informed how it goes. If you want to change Light Energy into Mass ( grass) then it's ALL ABOUT THE PHOTONS and you must have quite the photon machine right there.
