Samsung horticular linears

Very soon what will be available from most manufacturers is what is called narrow band phosphor to achieve higher performance.

A lot of led packaging companies have started to use the phosphor from GE including Cree, Nichia and lumileds.
I think Nichia was the first, but nichia have changed it slightly so instead of a peak @630 nm they have the peak @660nm

Aloha & GE seems to be making record progress since last fall. 2.8 in November is now 3.5 at the Amsterdam show? I am not impressed by their whites.

Its easy to get high efficiency if you are only using 660 nm. Just look how efficient the new Cree 660nm is, next year the 660nm will hit about 4.4m/joule, I have already seen what is in development.
Can't just grow under red lights although a very small amount of blue is all that is required to combine the spectrum to get results.
The highest efficiency blues are tiny LEDs that are used in mid powers, adding a bit of phosphor to that blue doesn't drop efficiency all that much and this is why everyone is using white mid power LEDs with a 660nm kicker.
We will continue to see jumps of around 8-10% in efficiency each year for the next few years, in theory there is only so far all of this can go and we are already past the half way point.
I believe something better than LEDs will come on the market before the peak is reached.

Aloha & They say they are 3.5 now. https://www.ledsmagazine.com/horticultu ... ze-element

With heavy 660nm that is possible including driver loss, not with white, not yet anyway.
Things change a lot in a green house. It is very different to growing in a room that has no windows.

I think one of the issues for Samsung is their reds

Oh, and do people have opinions on what to expect from such a spectrum as a flowering light?

Aloha & at 5.4k CCT I think shorter plants with more color due to more blue.

I saw research which stated that increased blues effect affects until 20% blue and then cuts out. I imagined the issue in flowering with high color temperatures was lack of red, but when I look at the samsung linears, they seem to have enough. Somehow I imagine Samsung has put more research into their agro spectrum then most of the companies out there. I find it facinating that they selected a spectrum that goes against general grower wisdom. I can't assume they are irrational. Maybe they see this as a salad farm spectrum, but if so then why the extreme power of 25w/ft?

Teknik! It became clear to me that Samsung is untrustworthy, when they blackmailed phone customers on warranties on burning phones. They refused to honor warranties unless customers signed a nondisclosure aggreement. Since they were trying to hide spontanious combustion from their customers, they basicly made a deciscion to allow for the death of customers to save face and money. In some ways the whole issue blew up in their face. I definatly would not want to partner with them.
This said, I would have to see the agreement between samsung and HLG to comment on it. I really don't know any of the relevant data to judge how Samsung saw this agreement. My guess is that the agreement was for samsung to provide top bin, and for HLG to purchase them.

A 5 minute search into what samsung has been presenting as their agro strategy some years back did yield some hits. They announced a 1.3billion research budget on these areas for the period of 2013-2023. I would love to hear about HLG's research budget in this period.
Is it in any way possible that either side really saw this as samsung outsourcing their agro activity to a company who does not even have a research dept?
I think everyone in the DIY scene has an idea of how useful the top bin chips have been for HLG, allowing minor differentiation in a very generic field.

Samsung has ROI at the core of their LED design, they aim to make cheap products and sell them cheap. HLG makes a similar cheap product and tries to sell it expensive. HLG's actions are directly opposite to Samsungs strategy. So while they announced a product level partnership, Samsung could never have announced a strategic partnership if there is no harmony between strategies. They would loose more in stock value, then gain in sales
