If amalgam based fluorescent lamps are more friendly to the environment? « on: March 29, 2010, 06:13:10 AM » Author: dor123
Recently in Israel, an amalgam based helical CFL lamp named Hyundai TEVA are marketed (Mainly in supermarkets, not in Ace hardware like stores). I don't know if this lamp is a geniue lamp of Hyundai as the word TEVA is a hebrew word but the advertisement tell that this lamp is more environmently friendlier as is contains an amalgam and no liquid mercury. Is this true?

Amalgam is quite strong bond for the mercury, so if the lamp break, much less of it would be released.

If the additional metals in the mercury amalgam changes the mercury spectral features? Or the atomic spectrum is remains that of the mercury?

During operation only the mercury evaporate from the amalgam (by distillation - it has the way lowest vapor pressure), so other metals do not influence the spectrum at all. Amalgam is used to allow higher temperature operation, as strong bonds between metals and the amalgam ensure, then the amalgam behave as "cold spot" (it's temperature is the parameter defining the mercury pressure), even if physically way hotter then e.g. the bulb wall. The same strong bonding is the "force", that prevent the mercury to leave, when the lamp break.
