Brighten up your entrance way, patio, balcony, garden , pool, or hot tub with the Cazador-del-sol Inspirational themed stakes which work both outside and inside the home. This high quality product is made in Germany of a special acrylic material. Inspirational stakes collect invisible shortwave UV spectral light and then convert them to visible longwave light that you can see. What you see is that the edges and the actual wording on the 20” Tall x 3” Wide stakes have a glow which looks almost fluorescent or neon. All of this happens the very moment of sunrise and ends the moment of sunset. This is not solar power nor does it have any batteries. Totally safe invisible shortwave spectral light source. Even on a dull cloudy day, rainy day, or during a snow storm- the glow is there from sunrise to sunset.An excellent modern addition to your suncatcher collection. YELLOW Color
