I have a Coleman CLX lantern from 1984, which also has "model 290" stamped on it. As the 290 was to later become the Powerhouse model, I assume it has a larger than average generator and fuel delivery system. I wonder if it could benefit from larger mantles than the standard #21s that I have always used. All of the #21 mantles that I have are the old thorium type, so when I finally run out of those I'll already be losing output to the now standard yttrium mantles. Does anyone know if the Coleman #20 mantles would work with my lantern, and would they give off more light? If not the #20s, then how about some other size or brand?
