the current bulb i need to replalce is
[FULL SPECTRUM LAMP; 150W A21 FROSTED; AVERAGE 5,000 HOURS; LUMEN OUTPUT 1550; Medium Base]
right now 6 of these lights the computer room.
the below is http://www.amazon.com/Spectrum-Light-ALZO-Compact-Fluorescent/dp/B0018OS06S
is 27W compared to 150W that I am trying to replace.. what is the practical effect of going up or down on Wattage? (it is more bright proportionally or does it take about more electricity intake or both)
2)how does all of this relate to 'lux'?
why is the 'lux' not mention in the first amazon link? or does it go by another terminology?
