Why mercury free HPS lamps, are less efficient than standard HPS lamps? « on: August 21, 2022, 07:08:23 AM » Author: dor123
They have high xenon pressure (300 torr), and the sodium spectrum broadens less to the red and more to the green, so they in fact should be more efficient than high xenon pressure HPS lamps with mercury. Why it is this?
