Does anyone know what combination of gases would provide a good infrared light source in the range of 700 - 1100 nanometers? The intended use of the gas would be in a neon-type tube to provide a continuous, diffused light source. Alternatively, does anyone know of any continuous infrared light source that provides: diffused light, can be in a bendable, yet rigid form up to 5 feet long, does not get hot (~ 5 watts would be nice), no power cycling, and has a good long life span (like a few years). I know, that is probably asking alot. If any of those details do not make perfect sense, it is probably due to my bad interpretation of the requirements. I am looking for this information for a friend.

Mixing gases in "neon" tubes generally doesn't work. The one with the lowest breakdown voltage fires first and takes all the load. John Nagle

The surface of the inner electrode and the inside of the sphere where your hand makes contact is pink. I believe that there two gasses with different breakdown voltages. Different gasses glow in different areas due to differing charge densities at the electrodes and in space. Does anyone have a better theory?
