Incandescent & Fluorescent Lightbulb, Types & Information

 

Incandescent & Fluorescent Lightbulb
Fluorescent light sources (contain gases in a tube but have no filament)
Fluorescent light sources (contain gases in a tube but have no filament) These have been around for many years and are better known as the long white tubes commonly seen in utility ceilings. Recent technology has reduced the size and improved the efficiency. Many different shapes and power options are available. The benefits are low power consumption (around 20% of a conventional light bulb) and long life (up to 8000 hours). They are ideal for lights which need to be kept on for a long time. Many people assume fluorescent light is ‘cold’ but ‘warm white’ lamps are available which improve the colour.
Incandescent light sources (conventional filament bulbs)
These are the conventional bulbs which we all recognise and their chief advantage is the colour of light they emit. Colours of objects are generally more accurate with this type of light bulb and they impart a warm feeling to a room. The disadvantage is that they are inefficient by modern standards and have a relatively short life (around 1000 hours). Incandescent lamps come in a variety of shapes and sizes and have a number of different fittings: Bayonet cap (BC), Small Bayonet cap (SBC), Edison screw (ES or E27) and Small Edison Screw (SES or E14). The Edison screw types are becoming more popular in the UK. Several different coatings are also available with the following properties: Pearl is an all over frosting which diffuses the light and is best used in a light fitting with shades. Clear bulbs are more attractive when used in fittings where the bulb is visible or a sparkle is required such as crystal chandeliers
