i will just say that the sk400+ has not perforned as advertised for me....it will grow buds...it veg's well..
.i would get PLC, TASTY, and few more etcs from people who make them here..
i would put 250 w of cobs against the 400 and and gigure i would come out on top

well, there is nothing "wrong" with it yet since almost nobody has one & there is not a single published grow or any data to go off of.
Spectrum King has moved from the Cree MKR that was in the SK400+ to something else...
The new white diode in the 600 watt model appears to be a 7mm x 7mm or 8x8mm package. And after an exhaustive search, I cannot find any diode in Crees line up that has this size and is consistent with initial performance data from the SK youtube videos.

-so lets put aside our feelings for the owner of the company & the way he presents and markets his lights, and lets dive into the data about how this light can theoretically perform. That would be my approach.

-we can begin by trying to identify the diodes, or speculate on what diodes and drivers are in it.
so far i see:
( 168 )white diodes, 4000K ? , if not Cree, LumiLeds??
( 24 ) 630 or 660nm XPE
( 4 ) "other" UVA?

Thank you old mother and growmau5 for the info,I've seen your videos and tutorials Growmau5 and respect your opinion so the hunt continues just started growing and still have a few weeks to find flowering lights.oh yeah Growmau5 he mentions you in one of his videos nothing bad was said he said you are doing a good job informing people about lighting.
Thank you again
 
Osram Releases New Horticulture LED Series for Commercial Growing Applications.
http://www.ledinside.com/products/2...ed_series_for_commercial_growing_applications
​
OSRAM ZELION® HL300 series of fully spectra tunable and dimmable horticulture LED lighting fixtures from OSRAM SYLVANIA will be available mid-July for use in various phases of crop growth. The series, which includes the ZELION HL300 Grow Light, ZELION HL300 Grow White and ZELION HL300 Sunlight, were designed to meet the specific growing needs of commercial greenhouses, garden centers, research facilities and universities. These long-life LED fixtures use superior OSRAM Oslon® LEDs from OSRAM Opto Semiconductors that emit light in the photosynthetic active region of the visible light spectrum (400–700 nm) for optimal plant growth. UL-certified for horticultural lighting and RoHS compliant, the fixtures also offer the highest micromoles per watt compared to similar class LED fixtures.​

​
“With a uniform light distribution that is unparalleled by any other LED horticulture fixture, and by offering features such as tunability and dimmability as standard, we are delivering high-quality horticulture solutions that will enhance our customers’ greenhouses,” said Hossein Aghamehdi, business unit manager, OSRAM SYLVANIA. “Designed to withstand crop production environments, the ZELION HL300 series provide the necessary spectra that plants need for superior photosynthesis and optimum energy savings.”

When evaluating LED solutions, it is important to check on two parameters: the temperature of the LEDs when the fixture is running and the light distribution on your plant canopy. The ZELION HL300 series is equipped with a patented active cooling system that maintains low LED junction temperature ensuring long LED life and uniform spectra over the life of the fixture. In addition, the portfolio is designed with a patent pending optical system providing a uniform light distribution that is unique in the industry. The fixtures are fully dimmable and spectra tunable to meet the crop life cycle needs using PC based (Windows XP or Windows 7) interface software and controllers used to manage green¬house processes. The optimized fixture design makes the fixtures easy to install and provides the smallest shadow footprint compared to similar class LED fixtures. Compared to alternative HPS and MH technologies, the ZELION series provides a savings of up to 50 percent in electricity costs, using only 100 to 600 watts. The ZELION HL300 series is interface-ready with other commercially used greenhouse control systems, and are available through authorized distributors. The series includes:​

  • The ZELION HL300 Grow Light, designed for horticulture applications where supplemental lighting is required to enhance crop performance and productivity,
  • The ZELION HL300 Grow White, which has a combination of the Grow and Sunlight fixtures' spec¬trum, and is used in climate chambers where a higher photosyn¬thetic activity is required or by growers requiring supplemental light where color recognition and rapid, healthy growth are key factors, and
  • The ZELION HL300 Sunlight, which is recommended for growth chamber applications where natural light is important or for supplemental lighting where color recognition is important, such as in a garden center. To accommodate an increasing demand from plant researchers to garden centers, a spectrum was designed to closely match the light coming from the sun.
 
Hey Im new to LED's. I usually do all of my veg with t5 6500k bulbs. flowering I use hps but this year I think Im gonna let my plants finish outside.

I was if any of the companies are Japanese, and of the Japanese ones what people thought of the lights. I want to stay away from anything made in china. Its hard to know what light is the right light to invest in because Ive never done anything with LED's yet. I plan on using it for autoflowers as well as regular vegetables.

Thanks, I know it may be an odd request, but Im hoping someone has the answers Im looking for.
