Keeping in mind this:

If you are using lights in the winter or in the greenhouse, you are getting "free" heat based on the 1 watt = 3.412 BTUs. conversion factor.

Also, HID lights are too hot is not entirely correct. HID lights generate less heat per watt of light output. They are hotter because the heat is more concentrated in smaller areas.
