Looking to do cool tubes as I hate fighting heat. I know DE bulbs are superior for HPS in terms of efficiency, But they shouldn’t be cooled due to the nitrogen jacket being a poor insulator and thus allowing the temperature to shift with cooling and subsequently efficiency and spectrum suffering.
Now my question is:
Are DE CMH bulbs susceptible to the same problem? Or can they be air cooled without fear of losses (other than the glass in the fixture).
