Digikey will be selling the new Samsung Horticulture Linear LED strips.

Still only 159 lm/watt diodes...
Double output of EB 2ft strip but CCT is 5150 which means VEG...
The specs given are run at 1200mA - another issue with many drivers not fitting.
It will only get better....

159 lm/w for the strip not the white diodes. There are also red diodes on the strip ;) What you need to look at is PPE wich is 2.74 umole/j. There are bunch of 1050mA drivers out there, that's close enough to 1200mA for me. What bothers me is the Vf of 43V which will be a bit trickier to match with drivers and still getting high efficiency on the drivers side.

The lm/watt doesn't tell the whole story as so much of the energy is out of the lumen curve. The 2.74 umols/joule is where they really shine (no pun intended).

New warm white strips have 660 nm LEDs. Will compete with the ChilLED and Horticultural Lighting Group enhanced spectrum products. Uses White LM301H & red LH351H LEDs.

SL-B8R5C9H1WW is the one foot strip. (not available yet)

SL-B8R5C9H2WW is the two foot strip. (not available yet)

Looks really interesting. But the white diodes are cold white, 3000k would be preferable. Any ideas about price?

Price will probably be good, but I'm not liking that giant blue spike. It's gotta be +30% blue, looks like the white is 5000K 80CRI.

LM301H comes in 90 CRI options. Would be nice to get that in strips, just 3000K white.

These strips would have a pretty good ratio using the reds plus 3500K. Someone would just have to talk them into making a batch.

Emerald0siris found the datasheet download link for these LM301H diodes. I'll repost it here too.

The data sheets have been up on the samsung site since they made the announcement.
They are a minor improvement over current diodes, but this isnt new technology here or anything. Just normal product progression imo.
spectrums are a tad more rounded out and they look like they deal with heat better.

If you look at the L2 datasheet's SPD and compare it to the LM301H sheets 5000K 80CRI is the closest match minus the red boost. Someone should digitize the L2 SPD and figure out the exact BGR values. It's difficult to justify going much over 15% of 400-500nm range. The best phosphor seems to be able to do is satisfy that requirement and create a spike between 580 and 680nm. Logically 90CRI does this best with peak at 630nm falling off to 580 and 680 relatively equally. Perhaps not perfect but pretty good for phosphor. Advancements in color need to enhance this low blue/very low green/high red potential and maybe spread the 580-680 more equally, all at competitive cost and efficiency levels.
