• This work theoretically evaluates light sources currently commercially available for the suitability to drive photoreactions. Comparative evaluation of different light sources reveals significant advantages of light‐emitting diodes (LEDs) in the near UV and visible region, underlining the general superiority of narrow‐band monochromatic light sources for photochemical processes. A generic analysis based on the average volumetric rate of photon absorption shows the limits resulting from physical fundamentals and the importance of the photon fluence rate for process intensification. A comparative study of light sources reveals significant advantages of light‐emitting diodes (LEDs), underlining the general superiority of (quasi‐)monochromatic lamps for photochemical processes. A generic analysis shows the limits resulting from physical fundamentals and the importance of the photon fluence rate.
