LM301H EVO

[f-e]

Yes.. the EVO model of the B and H are now appearing.
The H, as a horticultural product, no longer states CRI or has colour temperatures just a few kelvin apart. They have dropped that. Overall the improvement is from 3.10 to 3.14 which is rather piffling. It comes from a better rear reflector. The real change is moving the red peak from a little over 600nm to about 580 where sodium lamps sat (yes, past tense).

Words.. who needs um.

That's the EVO on the left, Standard on the right. Please note the 4 colour temperature boxes are not the same. Being 2200 2700 3000 3500 for the H, and 3000 4000 5000 6500 for the EVO. I wasn't aware when I initially merged the pics. Below I have overlayed the new 660 3.9umol/J red they do, and draw a yellow line to show how they will sum up. I have an issue here. The 630nm dip. We are yet to see a grow done with them, but I feel the EVO won't grow like the standard H. However, we tend to add some 660 anyway. That 630 dip though.. we might need to add some 630nm red's (standard red, sold as horti or whatever)


Any thoughts? Seen a grow yet? Supplier?

I think we would need the 4000K with 630 and 660

Hello friend f-e, for those diodes here in the UK I found HLG group and invisible sun (which for what I researched don't have the best reviews...).

Also for what I I've heard on youtube the red diodes are 20% more photosynthetic then the blues... While the blue spect produces smaller and more compact plants it shouldn't be more then 15% of them in the fixture...

in the USA, this one should be good:

Kind regards

Made me count..
The 3000K graph has the blue spike covering about 8 squares, and the larger spike covers perhaps 50 squares. I think with some 630nm added, we might see another 10 squares covered. With the cooler lights, this 15% could be an issue though.

Is it 15% now? They keep moving it around. If just centered on 450nm, about 15% is suggested by the sunlight spectrum.
Never any aqua blue in our lights. It seems unrepresented.
