TDP Lamp (Far Infrared Mineral Lamp)
This New and Improved TDP Lamp features a unique, oversized (6.5 inches in diameter) black round plate clay-coated with a mineral formation of 33 essential elements such as Fe, Se, Mn, Zn, Co, Ni, Cu, Cr and K. When activated by a heating plate from behind, the mineral plate emits penetrating far-infrared energy ranging from 2 to 25 microns in wavelength, and 28 to 34 mw/sq.cm in intensity.
