How to Choose LED bulb (4)
(4) Plan for placement
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.
