Greenhouse supplemental lighting

Hi,
A greenhouse is somewhat a grow room... Sorry, if I'm in the wrong forum.
looking into supplemental LED lighting for a greenhouse I came across a few issues and more questions. My trusted light guy on alibaba says a lot are going with the typical bar design used by hortibloom, spydrx and many others. That design does create too much shade for my taste. You're probably losing 40-50% of the direct light that way. Second I thought of these here https://opticledgrowlights.com/products/phatslim-1xl. They surely would cast less of a shadow. But I worry about the black heat sink being right under the cover and maybe collecting more heat that it actually would create.
I don't know, if it influences anything, but I would be using light diffusing acrylite (still waiting on accurate data sheets, tho) as a greenhouse cover or light diffusing PC.
Then looking further I found these two:


Has anybody had experience with these lights? I have watched a video with the cali lightworks guy, which I thought was quite impressive. The lights don't say anything about coverage...

Dutch lighting innovations has a new led designed for greenhouses, I think revolution micro avicci fixture might also be good choice for greenhouse?

Is it warm all the time where you are at if not and you could use some heat I think a lot of the de fixtures would work well in a greenhouse.

I'm looking for a place in Spain, so I can do without the heat...
I'm obsessing a bit about the CL GH PRo 340. How is it possible to produce 3.0 umol/J drawing only 340W? Is it bullshit?

That's just a measurement of how efficient the light is not total light output. And if you notice how red the spectrum is that explains why the efficiency numbers are better compared to white LEDs. They do seem like a nice fixture for a greenhouse. Depending on how tall your greenhouse is I'd still consider using de hps if your worried about shadows, as you get one fairly small shadow for large coverage area.

No, I'm really done with all the old school lights. The light quality drop off is a rip off. And I was tired of using them before. I'm planning a small solar passive greenhouse, so heating even in winter will be around 1kW, probably less with the lights. Max height will be 1,8 m above the canopy. I'm trying to find par readings, but there don't seem to be any. Ideally I would like to have a DLI of 50-55 mol on days where I might have a DLI of 10 mol.
