Hydrogen for lighting

Lighting via the use of hydrogen can be accomplished by the phenomenon of CONDOLUMINESCENCE, a cold process. A phosphor is spread on the inside of a tube similar to the conventional fluorescent lamp. Upon coming in contact with the phosphor, small amounts of hydrogen combine with the oxygen in the air to excite bright luminescence in the phosphor. (Is this the secret of the mysterious "perpetual lamps" as found in ancient tombs?)
