time to start up a new thread.... *laughingcryingsmiley*
for incandecent and fuorscent light of the same voltage, i have the understanding that fuorscent light performs many times better, since incandecent light wastes most of the energy as heat (entrophy, anyone? yes, your light bulb has help in pushing the time arrow forward) -- 90%, in fact. However, understanding physics does not help me in understanding the practicals of plant keeping.
So here is my question:
by wattage reading of the bulb, does the wattage measure the light bulbs (incandecent / fuorscent alike) output ( watt /per meter^2 ) or the electric intake ( power = voltage * current)?
and how much better is a fuorscent than that of incandecent?
