Just a great idea. Through the thick, uneven glass, the light is emitted in varying degrees of intensity. This looks very pretty. Have the sun Glass of receipt simply placed on the window (sunny) and turned on in the evening at dusk, to see how long it will light. After a few hours I am tired to bed and Solar Jar still shone ... strong buy recommendation for decoration muffle, since the glass also as throwing a beautiful light. But the imagination in the assembly of the lamp are known no limits. And just the way that other lamp on and off again was important to me, because we want to use indoors and use there as needed. Strong buy recommendation.
