Unless you buy your grow lights from the tanning bed store it’s highly unlikely that they’re supplying the wavelength and energy required to cause cellular damage. In any case, a lot of fancy grow lights are just hokum. Take the money you’d spend on an expensive grow light and spend it on a bunch of decent full spectrum LED bulbs. More light is going to be better than perfect light unless in an industrial application where vegetative production is carefully sheparded to produce bigger crop yields.
