Nichia 757 optisolis vs samsung lm301 leds

Orblight · Jan 21, 2021

Any thoughts on these 2 diods? I've seen nichia ran tests on Samsung's lm301 proving they don't get the performance Samsung claims but of course they would say that.
Nichia are made in Japan and claiming some crazy numbers like 3.0 umols/j and a cri of 98 - 100
Anyone have experience or knowledge with the nichia 757 optisolis?

Cutter and Grow Lights Australia have boards with the optisolis chips. Not a huge amount of grow reports but they seem very promising.

Yeah that's where I seen them, an they do seem very promising but as you said i can't find too much info about them or anyone using them.

I think the difference is very marginal, unless you go for one of those high cri chips, you almost never see samsung with other than 80cri.
I dont think 98 cri chips will hit 3.0 ppf/w at nominal. Generally id say 90 cri is enough, it moves the red bump enough.

and what about Osrams osconiq s 3030 3v chips ? they have cri 90 quantum dot thechnology with ultra hich efficacies and standard cri 80 with with bins hitting more that 230 L/w at nominal.

They seem real nice but not very available and o so pricey, even with massive moq they are still over 10ct per diode. Where did you get those?

Nichia will release new leds based on the GE Trigain phosphors which will lift efficacy of 90 CRI to the same level as 80 cri
if you need help making strips, we just commissioned a new smt system

When do you expect they'll be available to buy on strips?
