Large round globe lamps are normally used in large pendants or table light fittings which can accommodate a large diameter or length of globe bulb. Available in clear or frosted glass finishes and with Edison screw or bayonet cap bases. Many of the more decorative large lamps will best suit a bare flex allowing attention to be given to the design of the bulb and creating a very interesting fitting rather than mere illumination.
When choosing a lamp (bulb) you first need to check you have the right base, so Edison screw, E27 etc. Once you have found the right base you will then need to work out if the length of the lamp is dictated by the size of the shade, you would probably not want the lamp to protrude outside of it as this would look rather strange! So, when you have worked out these two points you can choose a lamp which takes your fancy. Whilst we may suggest a decorative globe on a bare flex there is no reason one would not work within a metal pendant especially if being viewed from underneath as it adds to the appeal.
