energy quiz: You replace a 58W Fluorescent tube (5200lm nominal) by two sets of 3x 8W/1100lm LED bulbs, with each set switched separately. How much energy do you save?
One set is placed directly over the main table.
Known unknowns:
a) How much does a florescent fitting take with that tube?
b) How much light does either combination actually give?
c) Will we turn both sets on or just one most of the time?
