This is about low-energy light therapy.

I don't know anything about it, but some meta analyses suggest that evidence is still cautious regarding its benefits:

"Meta-analysis was performed for the variables: time until reach exhaustion, number of repetitions, isometric peak torque, and blood lactate levels showing a very low to moderate quality of evidence and some effect in favor to phototherapy" [1]

"In exploratory analysis, the results showed that phototherapy was effective only in the exercise protocol with localized exercise with large effect size" [2]
