Judaica Lights offers eight lithophane designs, each reflecting a beautiful work of Judaica Art to use as a Yahrzeit light in memory of a loved one. Lithophane is a form of art dating back to the 1820s, and the artists at that time used porcelain to create this unique art. We custom-make our lithophane lights using 3D printer technology. Our lights are designed to be used with any 110-120 V AC outlet, are equipped with an on/off switch, and have prongs that rotate 360° allowing images to remain upright no matter the direction of the outlet. Each light comes with a 7W C7 Clear LED light bulb that lasts for up to 25,000 hours of use.
