How do I get the brightest light bulb?
Choose a bulb with more lumens for a brighter light.

Is it better to turn off fluorescent lights or leave them on?
CFL Lighting
Since they are already very efficient, the cost effectiveness of turning CFLs off to conserve energy is a bit more complicated. A general rule-of-thumb is this: If you will be out of a room for 15 minutes or less, leave it on. If you will be out of a room for more than 15 minutes, turn it off.
