Made a mistake and order a light up mask from a closely named site, "Thelightupmask,com". Not the same site as "Lightupmask.com" and not the same quality. The other site took over four weeks to processes and ship the order. Lightupmask.com. mask arrived in a week and the mask was a lot better quality.
It is surprisingly bright and the colors are beautiful. It is a well-known fact that blue lights last longer than others. I got two masks. The one that used blue light lasted longer than four hours. For the one that did not use blue lights lasted less than four hours.
