Here at Florence I.T. we are absolutely dedicated to conservation, not just trendy new "green tech". We recently replaced some of our already efficient CFL lightbulbs with even more efficient LED bulbs. In the interest of sharing our experience here are some photo comparisons of the light output. The LED light output is far less, but uses only 1/4 the power, and is appropriate for this specific type of task lighting. Search online for Nichia LEDS if you're interested.  More reviews to follow with alternate lighting, gear and tech as it's needed in our office or for our clients.
