Lasers flux their muscles: The Norrish type I and type II reactions of 1,3‐indandiones can be controlled by judicious choice of light source. Selectivity depends on photon flux, not wavelength. Laser irradiation lead to lactones (type I); conventional lamp irradiation gives diketones by fragmentation (type II, see scheme).
