I’ve had three now,top bin components,high PAR ,I’ve had no other LED’s to compare to ‘but they easily match a 600w hps,I’m using the VST240’s,pull 237watts from wall,so plenty of energy saving,I’m sure I purchased my first late 2019,so these were well advanced back then.And are still up there with the best,try them ,pure quality.Read the other testimonial’s,these lights are apparently better than Spider farmer,viper etc. Topgrow68
