    I just switched from a 400 w MH to a 600 w dual spectrum HPS and I noticed that the temps feel higher that when I last used a 600 w HPS without the dual spectrum range.

    Does the HPS light with the fuller dual spectrum tend to produce more heat than a comparable HPS that is basically at the red part of the spectrum?

    And is there any value to using a dual spectrum in flower as opposed to a single red spectrum light?

    Thanks for any advice.

    Been awhile since I grew with a dual spectrum. When I did the bulb had 2 gas filled glass tubed. 1 was hps, the other was mh. The bulb gave off quite a bit more heat then just a hps bulb. Mh always do.

    Advantage was less stretch, denser buds in some instances.

    If you're using a brand name bulb like Hortilux, their web site might have data charts that show what you want. I didn't see anything for heat but they do have theoretic light distribution charts.

    THey did have a BTU calculator base only on bulb wattage... http://www.eyehortilux.com/education-room/btu-calculator.aspx
