Full spectrum would be more optimal, but the 5700k "daylight" LEDs I'm using still work very well. They're probably lacking a bit on the red end of the spectrum compared to a full-spectrum light, but otherwise they cover the photosynthetic range pretty well. See page 19 of the datasheet for the LED spectrum: https://downloads.cree-led.com/files/ds/x/XLamp-XTE.pdf https://downloads.cree-led.com/files/ds/x/XLamp-XTE.pdf. And here for some decent general info: https://www.neherpetoculture.com/vivariumlighting101 https://www.neherpetoculture.com/vivariumlighting101. Anecdotally, I've successfully grown a range of plants in these including mosses, ferns, and orchids.
