A21 long life light bulbs which have a longer neck in several higher wattages up to 150 watt.

Most people have wanted higher wattage light bulbs to last longer in their homes or commercial buildings and change them less often, that's why we offer A21 long life light bulbs. Common to almost every type of lighting application has been the standard light bulbs that you buy for your home. Sometimes these are the A21 size bulbs which you might be familiar with, the ones you've probably bought for years in retail stores but never had this kind of life.  They fit in almost any light fixture, but one of the most common places that it's used are in table lamps, deep recessed and some kinds of sconce lighting.  It has a standard medium base and screws into sockets that are made for all kinds of US lighting.  They have multiple filament support which makes the lamp less likely to fail as a result of shock or vibration.  They are also filled with krypton gas which helps the filament to last longer as well.  These come in 75, 100, 135 or 150 watt versions in frosted or some with a silicone coating and a brass base.  We have them in higher wattages too, but those have a larger bulb than even the A21 which would be an A23 size.

These lamps were an early incandescent development and are one of the types we know as A21 long life light bulbs.  You might familiar with these in trouble lights in the automotive service industry or something you might use in your garage at home. They're used in these applications because they won't go out all the time when roughly handled.  If you're a commercial building owner, then long life light bulbs would be a great choice for many of the recessed lighting applications you have today.  Large commercial buildings are still a major user of this lamp where the labor cost to change out bulbs can get quite expensive.  The savings in this case can be quite extensive resulting in a quick payback on the higher cost of these bulbs.  These are also great lamps to be used in industrial situations on machines or in areas where manufacturing is going on as they are bright enough for better illumination needs.
