The original twin bulb fluorescent fixtures in our 2007 rig, I had taken one un-tampered fixture into the lab here at work where an electrical engineer measured the power to be 9 watts. My LED conversion dropped the power down to 6 watts, but the light output is way too much. I think I can cut the wattage in half again to 3 watts when reducing the brightness by disabling every-other 3-LED circuit. 3 watts per fixture would be real nice to achieve. But the right brightness takes priority over power savings.
