that are available. He grabbed a catalog and started doing a couple of different calculations to compare Lumens/dollar for the upfront cost, and Lumens/Watt for the operational costs. Hands down, newer fluorescent bulbs come in cheaper on both counts and provide a wider spectrum of light. ...

These lamps produce 17–22 lumens per watt, are the least efficient and most expensive to operate, and have a short lifetime of from 500 to 4000 h. Compact fluorescent light bulbs are replacing incandescent bulbs because they are “earth friendly,” useless energy, last longer (10,000 h),...
You should be aware that lumens are specific to the total amount of light emitted by the light source, while watts refer to the amount of energy consumed. As the levels of energy efficiency increase, the wattage decreases in relation to the generation of lumens. ...
