Light emitting diode (LED) light bulbs are poised to become the bulb of choice for many shoppers. With a recent price drop announced by GE, it is predicted that LED light bulbs might in coming years make compact fluorescent bulbs (CFLs) obsolete.
But not all LED bulbs are created equal.
Here is a conventional incandescent 60-watt bulb and its CFL equivalent:

The conventional 60-watt bulb has a life of about 1000 hours, and is rated at 870 lumens (the brightness or amount of light it gives off). But the CFL uses only one-quarter of the electricity (15 watts), lasts eight times longer, and produces slightly more light — 900 lumens — at least initially. That CFL cost a dollar or less.
The new GE bulb, called the GE LED Bright Stik, comes in packs of three at Home Depot for $9.97.

*MOUSE PRINT:
While it uses one-sixth of the electricity of an incandescent, and a third less than the CFL, it only provides 760 lumens of light versus 870-900 lumens for the other two. It also provides a paltry 15,000 hours of life — short for an LED.
It appears that GE has sacrificed longevity and light output for a lower price. Compare the specs of some of its competitors:

60-Watt Equivalent LED Bulb Comparison

“Conventional” refers to bulb shape
As you can see, prices and specs vary widely. The point of this comparison is to show that you shouldn’t assume that all LED bulbs of a certain wattage equivalent provide the same amount of brightness or have the longest possible life.
