You may be able to use this one as fire extinguisher, at its life is forever, as long as it shapes like fire extinguisher; I have an international patent for the Light Lantern or Bulb which can be exploded when touched nearby fires automatically like this kind of Edison Made-lighting Bulb... It is so simple and this will not put off fires, as this is hanged on the wall, not under the ceilings... As you may know or not, fire/heat/flame always go up-wards, not to the walls around,,,,, Therefore this lighting bulb should be modified to be hanged under the ceiling.. In Korea/China/Even in U.S.A., there have beeb similar fire extinguishers, hanging under the ceiling, with Halon or Dry Chemicals.... and today they can be found easily in Korea in the Apartments's Kitchen's ceilings... This is a just decoration in household!!!!!
