As a lighting store we realize that its often necessary to have a specific type, shape and wattage of a light bulb to meet a particular lighting need.  We carry light bulbs from Westinghouse as well as Satco and American DeRosa.  Wattages from the very smallest glow bulbs at 5 wats to the bright 300 watt incandescent and halogen lamps.  We carry 30/70/100, 50/100/150 standard base bulbs and 100/200/300 watt mogul base (large screw base) for 6-way lamps.  We carry candelabra as well as standard decorative bulbs in many wattages and styles including bent flame tipped, torpedo shaped, round bulbs as well as old fashioned "flame" bulbs.  If we don't have it we generally know where to get it.  The easiest way to get a bulb is to bring in the one that you are trying to match.  General descriptions and "I'll know it when I see it" will usually be a waste of time as the "standard" and most common amount to several thousand styles, shapes, colors, voltages, wattages and manufacturers.
