Unfortunately it is limited to only indoor and dark place. In stead of flash lamp or LED. PRIMARY Strobe Glasses are equipped with high speed LCD (liquid crystal display) controlled by CPU (Central Processing Unit). By blinking LCD in front of your eyes, you can get stroboscopic effect very easily anywhere and anytime as you wish. Yes, you can use it during your daily training outdoor under sunshine.More details
