With strips you have no real heat issues
True, the new EB Gen 2 I have tested run at about 45°C at 700mA.
I was thinking if the plant's canopy can be contained within a 4"-6" wide space (e.g. between panes of glass/acrylic/) the light could be easy to regulate to a minimal current with the strips very close to the glass. The panes of glass could be mounted to the grow light fixture.
After writing that last night I also gave some consideration to alternating the light from one side of the plant to the other. This way as the plant reaches for the light it could be easier to contain. Like alternate sides every hour. This could be done by doubling the number of strips or by using a solenoid to rotate the strips 180° when there are many vertical scrogs side by side about 8" apart. The strips would then be centered 4" from two sets of plants but providing light to one side.
This alternating sides would save a lot of power. At 4" from the strip (i.e. at the glass surface) the current can be adjusted way down and still provide 1500 µmol/m²/s at 4" away. At 6" (i.e. halfway between the panes of glass) inverse square will reduce the µmols to 666. With the double side , the minimum irradiance for the entire canopy will never be less than 666 µmol/m²/s.
I have seven of the Gen 2 strips and will be measuring the irradiance at various distances later this week. I'm estimating the current required will be less than 200mA. With the strips having a Vf of 20V, at 200mA the required power would be 4 watts per 22" strip.
A 1000 watt HPS provides about 400 µmol/m²/s at 1000mm above the canopy. At 100mm (≈4") the irradiance would be 40,000 times more or would require 40,000x less power. So, hypothetically, at 4" you would only need 1000/40,000 = 0.025 watts.
Up to 42 100W solar panels could be mounted on top of a 40' cargo container supplying more than enough power for the grow lights.
So if the canopy of each plant is contained within a 30" wide x 90" height x 4" deep area, you could fit 118 plants in a 40' cargo container. Each plant is grown in a 24" long x 6" wide x 12" height pot (2 cu ft) mounted on top a skateboard. The plants would be positioned on each side of the container as shown in the floor plan image below.
The skateboard would allow each plant to be rolled out to the center aisle for maintenance.
