Lifehacker, the personal productivity and "life hacks" site, is spotlighting a nifty little power management utility for Mac OS X called Lights Out from Northern Softworks. Adam Pash describes it as "your Mac's default Energy Saver tool on steroids, allowing users to set very specific energy saving settings."

Here's the features rundown from the developer's site:

• User configurable idle times for dimming the screen, spinning down disks, and CPU sleep.
• Customize Energy Saver settings for individual applications.
• User configurable idle time for logout.
• User configurable idle time for system shut down.
• User definable hot spots for CPU sleep and never sleep.
• Toggle Safe Sleep on and off.
• Delete the sleepimage file.
• Easily switch sleep on and off.
• Application based for easy installation and stability.
• Simple to configure and use.
• Illustrated Documentation.

Though I, like the Lifehacker crew, prefer free, a license costs a mere $8.99, which you'll probably earn back with these energy prices these days.
