SDS - I represent the Zelion HL fixtures. I'd be happy to publicly answer any questions you might have on the specifications of the Zelion HL fixtures. Mr. PSUAGRO will likely answer grower related inquiries as well as he is the horticultural expert dealing with these panels at the moment. Interesting things to come........

Questions first ....

1 ) Retail prices ?

2 ) Passively cooled ? Ok ...At what current the Oslons are being drived ?

3 ) Which drivers are being used ?

4 )What kind is the screen in front of diodes ? ( PMMA ? Gorilla glass ? plain optic glass ? polycarbonate ? other ? )

5 ) When -approximately - we should expect the new models ,featuring the 451 nm / 660 nm / 730 nm "combo" ,
hitting the market ?

Keep in mind ,please ,that i do NOT like R+B monochromatic diode LED grow lights.
They are made and intended for other uses ,than as a sole light source for Cannabis Sativa L. species .
Still...

There are always "exceptions " to the rule ...
Some that I just adore ...
For me and my humble point of view ,I would like to have and be a proud owner of two of these type
of solid state lights ...(R+B monochromatics )
One would be the Han's panel's and the second is the ZELION HL .
( AREA51 is also on my "top-5" wish list ,but those lights belong to another "league" ..the W+R one ...
For the moment being I'm a proud owner of ..one of my own built lights ..)

Anyway.
Zelion HL ?
Great lights ,top-quality ,worth to have and own .
Best "teammate" for white 4000-3000 °K COBs .
Period .-

Cheers.
:peace:

Not a an expert....lol.......and my major was waaaaaaaaaaaay easier than horticulture. I don't even wanna think about organic chemistry ATM, bad memories:eyesmoke:

going to start soon osramman

For the record - compared to me you are the expert. Took Ochem at UCLA and UCSD - wish one of them would have taken mercy on me. No such luck. I have faith that you will do great things.

Hello StardustSailor - pleasure to hear from you. These are some amazing lights as you already have gathered.


1 ) Retail prices ?

2 ) Passively cooled ? Ok ...At what current the Oslons are being drived ?

3 ) Which drivers are being used ?

4 )What kind is the screen in front of diodes ? ( PMMA ? Gorilla glass ? plain optic glass ? polycarbonate ? other ? )

1 ) Retail prices ? - Talk to PSUAGRO and myself, current pricing on www.dlplampsource.com

2. Passively cooled - no fans at all. 350-400mA nominal

3. Custom designed for Osram by leading LED OEM driver designer

4. Proprietary - the OSLON SSL80 LEDs have an inherent 80 degree lens. Additional secondary information is pending from Osram.

5. Unknown

Any additional questions, I am happy to assist the forum. Mr. PSUAGRO is currently the horticultural expert dealing with these lights.

Best Regards
Dan

I'm far from a horticultural expert, especially indoors............agriculture osramman , and most of my co-workers will tell you that I'm terrible at food crop management too.......lol

Plant scientists and LED luminaire manufacturers are continuously exploring ways to advance LEDs for indoor agriculture applications because of the inherent benefits. Every manufacturer believes they have a "recipe" that uses LEDs with different wavelengths to deliver a blended color spectrum that spurs photosynthesis and steers morphogenesis.

In my experience, many manufacturers are populating LED luminaires with (400-499nm) of predominantly blue LEDs for vegetative purposes and (600-699nm) of predominantly red LEDs for bloom/flowering. Research is showing that certain species of plants thrive under a blended color spectrum that includes a percentage of far-red (700-799nm), green (500-599nm) LEDs, and full spectrum LEDs. The goal of max yield/watt will be achieved by optimizing the ratios of different color LEDs and delivering a "recipe" that elicits a desirable plant response.

Surely you're aware of COBS, yes? They basically cover all the colors you listed, with an exception to the depth of far-red.

What may be some possible or existing benefits of implementing monochromatic LEDS in comparison to sticking with COBS?

I think COBS are the better approach for my applications.

How did that company become what it was if it just now figured out the secret sauce recipe? Government funded?

COBs have done a tremendous job of accelerating the adoption rate of LEDs in the general lighting space, especially for applications requiring higher lumen output and associated costs. I wouldn't disagree with you that they work well for your application. The downside is the large form factor associated with COBs. The physical size becomes increasingly more difficult to control light optically, resulting in a much larger luminaire.

In my estimation, the "secret sauce" is a moving target. LED manufacturers (i.e. Osram Opto, LumiLEDs, Cree, etc.) are heavily involved in research at Colleges and Universities and others to learn from plant scientists and others how different species of plants respond to varied color spectra. Based on empirical data, these LEDs manufacturers invest millions of dollars in the development of LEDs in order to differentiate themselves from the next best alternatives. Fixture manufacturers who are committed to staying on the leading edge and are financially able, introduce next-gen luminaires with LEDs that deliver greater value.

LUXdynamics is a privately held company with a manufacturing footprint in the USA (Nevada), and allocated a tremendous of their own time and money into the development of the LUXgro Series horticulture luminaire.

Phosphorus conversion white leds. Think outside your bubble.
