Many people would never think of buying an LED appliance bulb for use in their oven or refrigerator. However, the advantages of LED bulbs in unexpected spots are worth considering. Firstly, what is unique about how appliance bulbs are used? Often these bulbs are used very sparingly, only a few minutes every day when the refrigerator door is open, unless there are small children in the house, or when one needs to check on the roast, or if an indicator turns on. Secondly, they are often embedded in very, very hard to reach spots. In these situations LEDs shine and must be considered as replacement for the old-fashioned, Edison bulbs.
Traditional bulbs are fragile. They rely on an internal vacuum which allows a thin metal filament to heat and throw off light. LED lights, however, are more mechanical in nature and are almost inheritably tougher. They can take a beating and most modern LEDs are rated for occasional replacement at intervals greater than two decades! In fact, odds are by replacing the bulb in your fridge or blender with an LED the light will last longer than the appliance itself. Also LED lights do not dim as normal lights tend too. They will keep going and going at the same intensity as long as they need too. And if you are planning on using an LED with batteries you should know that because an LED appliance bulb is over half again more efficient than a traditional appliance bulb they will use significantly less power and therefore will extend the life of that battery to a much greater period than an old-fashioned bulb. So, if something needs replacing, why not replace it with something better and reap the rewards?
