The artificial flame bulbs put out minimal light. We used them in a 12- or 15-arm dining=chandelier in a former house -- very romantic, but you couldn't see to cut your steak by them. Strictly for atmosphere, not illumination!

The bulbs are just a slightly larger neon bulb and the discharge moves around on the large electrode.

They are not a good source of illumination.

Until mantles cam along to produce a hot surface, even gas lights did not produce much light.

Ok thanks guys, I think I will put my efforts elsewhere. =)
