Hear me out, I am starting to wonder if a light can be too efficient. I am running leds at 82 degrees and I am finding myself at the upper edge of what I am comfortable with regarding humidity. I run a big ac in a sealed room. The Ac can stay on top of the heat no problem but the massive rate of transpiration it is starting to fall behind on. Is not a big deal for me as I can turn on another Dehumidifier to pick up the slack. I think I am on the razor's edge of efficient light vs needing to add dehumidifiers or more heat to activate the ac more often. What I am wondering is if the next gen of lights that are more efficient will put out the same heat but more photons, resulting in more humidity. Is it more system efficient to use less efficient lights and stay on the edge or run the better lights and add a dehumidifier or heater? I am pretty sure the answer is, just adds a dehuie stupid but it is an interesting thought/issue that hasn't been a problem for me before.
