Mercury-free energy-saving lamp

Absence of mercury, a favorable CO2 balance, low costs of manufacture, and an excellent light quality are the features characterizing the electrode-free low-energy bulb ?3rdPPBulb? that was co-developed by scientists of the Light Technology Institute (LTI) of Karlsruhe Institute of Technology (KIT). KIT scientists contributed the mercury-free filling, fluorescent coating, inner coating as well as the geometry of the innovative bulb.
