Many different models and styles of LED bulbs are available in today’s marketplace. When choosing a bulb, keep in mind the following:
Estimate desired wattage: read the package to choose desired illumination level. For example, a 3W LED is equivalent in output to a 45 W incandescent.
Choose between warm and cool light: new LED bulbs are available in ‘cool’ white light, which is ideal for task lighting, and ‘warm’ light commonly used for accent or small area lighting.Standard base or pin base: LEDs are available in several types of ‘pin’ sockets or the standard “screw’ (Edison) bases for recessed or track lighting.
Choose between standard and dimmable bulbs: some LED bulbs are now available as dimmable bulbs.
Note also if your bulb will work in an enclosed light fixture: some do not.
