OK, poster here,
The fluorescent setup is 3-6500 k T12 tubes, one 3500 k tube and 8-warm white 23 watt CFLs, uses 307 watts including the small fan and can illuminate 3-1020 trays. The tubes and CFLs are several years old.
The 2-4 ft. LED fixtures draw 75 watts total and can illuminate 2 trays. I would guess the LED station, without fan, runs about 10-15 degrees cooler than the fluorescent with fan. The LED tubes are barely warm. These are FEIT LED fixtures. I have no info on the color temperature or CRI.
(Note: trays have been rotated between light sources in these latest photos)
I cannot account for the few yellowed leaves on the LED tray except they are all on the edges and may have received insufficient light.
Plant out here should start in about 2 weeks. The ground temp needs to come up about 10 degrees.
