Here are a couple of things to consider from cnet.com....
1. The popular colors available for LEDs are "warm white" or "soft white," and "bright white."
Warm white and soft white will produce a yellow hue, close to incandescents, while bulbs labeled as bright white will produce a whiter light, closer to daylight and similar to what you see in retail stores.
2.Not all light fixtures should use LEDs
Knowing where it's OK to place an LED will ensure that the bulb won't fizzle ahead of its time.
You probably know that LED bulbs run dramatically cooler than their incandescent cousins, but that doesn't mean they don't produce heat. LED bulbs do get hot, but the heat is pulled away by a heat sink in the base of the bulb. From there, the heat dissipates into the air and the LED bulb stays cool, helping to keep its promise of a very long life.
And therein lies the problem: the bulb needs a way to dissipate the heat. If an LED bulb is placed in an enclosed housing, the heat won't have anywhere to go, sending it right back to the bulb, and sentencing it to a slow and painful death.
Consider where you'd like to place your LED bulbs. If you have fully or semi-enclosed fixtures you need to light up, look for LEDs that are approved for recessed or enclosed spaces.
