an LED bright enough to lit up your room clearly has maybe around 30 watts, so that’s less than 1 kWh if you operate it all day. i assume a small LED (status indication LED) consumes maybe less than 1 W? So that would be 0,03 kWh per day, or about 6 g of sugar. I assume plants would be at a similar energy level, maybe even dimmer?

30 watts for 1600 lumens (about the brightness of two 60 watt incandescent bulbs) would be about 53 lumens per watt. Which would be pretty abysmal for an LED light.
The bulbs I run output 200 lumens per watt, or 4 watts per bulb to output 800 lumens. In my kitchen I run two of them (so, 8 watts total), and that’s plenty bright.
Those are particularly high quality LED bulbs though, and its more common for them to be less efficient than that. In my opinion its very unfortunate that crap bulbs with efficiencies of less than 100 lumens per watt (and correspondingly low lifespans) are so common. But even those would have higher lm/w ratings, probably from 70-80.
Most status LEDs are using ~0.05watts of power if not less, so 0.0012kWh per day (~0.26grams of sugar) is already more then efficient enough for a larger plant. Even with that bioluminescence is wildly more efficient then any LED since its basically the byproduct of a chemical reaction (like heat emission from our body’s while digesting)
This research slightly predates the above article but they touch on the fact the biggest barrier to bioluminescent plants is that plants tend to absorb the emitted light which could be solved by getting them to emit green light (and look at what color this current article has the plant emitting! Kinda cool to see scientists theorys theory put into practice)
