I've noticed that CMH lamps have wider thallium line than QMH lamps except green MH lamps. You can compared these two spectra of CMH and QMH lamps: https://www.lighting-gallery.net/gallery/displayimage.php?pos=-248652https://www.lighting-gallery.net/gallery/displayimage.php?pos=-251779Why this is happens? |

| Because the thallium vapour pressure is higher, as are all other elements. Ceramic metal halide lamps typically have a cold spot temperature about 200K hotter than quartz equivalents.

| So how green MH lamp have the same thallium line width as CMH lamps?

| Are you sure you are equipped to measure this reliably and not getting the camera saturated instead?

| And if there is no advantage of wider thallium green line in CMH lamps, the thallium dose can be reduced.
