This bargain-priced LED from Walmart shines bright (LED)

Walmart's "Great Value" line of LED light bulbs are bargain-priced efficiency upgrades over classic incandescents. Are they any good? Click through for a closer look.

The dimmable version of Walmart's 60W replacement is a 10W bulb that puts out well over 800 lumens, making it a solid choice for efficiency hounds.

The soft white version shines at a yellowy color temperature of 2,700K.

There's also a daylight version of the bulb that puts out a whiter tone of light at about 5,000K.

The packaging for the soft white and daylight versions of the bulb are easy to mix up -- the same goes for the dimmable and non-dimmable versions. Make sure to double-check that you're buying the right one before making a purchase.

The bulbs are dimmable, but they don't dim down much lower than 20 percent. They also flicker at low settings on certain types of dimmer switches.

The dimmable 60W replacement version of Walmart's LED costs just under $5, making it a no-brainer upgrade over incandescents. But it isn't such a slam dunk compared with other low-cost LEDs -- read the full review for the full story.
