This is the largest version of what people have come to know as standard size light bulbs. These are the bulbs which you might be familiar with, they have a much larger bulb and a longer neck too.  The "A" shape was one of the first designs and continues to still be the one most people use.  They fit in almost any light fixture, but one of the most common places that it's used are in table lamps and sconce lighting.  It has a standard medium base and screws into sockets that are made for all kinds of US lighting.  Although it's popular and inexpensive, it's not always the proper light bulb to be using.  First of all, the A23 light bulbs have no light control associated with them, so it's important to select the right fixture.  This bulb sometimes is the only choice because it comes in higher wattages, up to 250 watts in the 3 way version and the neck is long enough to be put into a deep fixture housing. If you desire greater light control, then perhaps you might need a incandescent flood light instead.  This will get you a directed beam of which is more controlled.  But sometimes people put them in deeper reflector cans which will fit while directing the light produced by the lamp.

Incandescent lamps are the type that were developed earliest of any of the other kinds and these developed into what we know as the A19, then came the much larger A23 light bulbs.  There are several different types of these lamps in this shape which include long life bulbs, clear, frosted, and the 3 way light used for reading.  The soft white bulbs are the ones most commonly used for reading and table lamp fixtures and goes up to 250 watts.  It's a long history with this lamp and most of the improvements have come with longer life versions of these.  The long life A23 light bulbs are the same physical size but have multiple filament supports that protect against vibration and rough use.  In fact, these are sometimes called rough service light bulbs. We have a variety of wattages from 100, 101, 105, 150, 170, 200 and the 3 way 50/200/250 version. For older people, this higher wattage is needed for visual acuity and for just plain reading well. Although there are energy saving compact fluorescents to replace higher wattages like this, the physical size is still larger to be equal to the same light output. So there are some choices you would need to make on the essential amount of light you would need and whether you can live with it or not. If energy savings is not a concern, and you want to get the maximum amount of light in a regular size light bulb, then these A23 bulbs will still be a good option for you.
