What intensity is “high-intensity?” The article doesn’t give a number. Is this something that can be done with a few bright LEDs or do you need a specialized lighting array?

If you follow the links to the supplementary info it gives you intensity level, for example "The prepared dish was placed in a blue LED irradiation device and irradiated at 1.25 W/cm2 for 3 h."
As a reference, noon sunlight is very roughly 1000 W/m^2 or 0.1 W/cm^2, so this is pretty intense and I suspect would not be eye safe.

The abstract at https://pubs.acs.org/doi/10.1021/acssuschemeng.5c03907 mentions a power of 1.25 W/cm2
