CFL Bulbs

CFLs (Compact Fluorescent Lamps) are energy-saving bulbs used in lighting fixtures. The lamp consists of a fluorescent tube which has been made into a shape the same size as a traditional incandescent light bulb.

How does a CFL work?
Compact Fluorescent Bulbs contain gases which are given an electric current. This current creates UV light which excites the gases. A phosphorous layer is then produced on the inside which glows, giving off light. There is very little heating involved.

What shape are CFLs?
Compact fluorescent light bulbs come in various shapes, such as:
Candle bulbs represent the shape of a flame, with a pointed tip.
Globe bulbs are spherical shaped.
Spiral bulbs have a fluorescent tube which is shaped into a spiral curve.
Stick bulbs usually consist of multiple tubes which are straight.

What colour are CFL bulbs?
CFL light bulbs come in many variations of white. They are most commonly classed as "Cool White" or "Warm White", which describes the colour temperature of the light that the bulb emits. Colour temperature is a measurement of the light output, given in Kelvin (K). The higher the value, the cooler the white and the lower the value, the warmer the white. For example, 2700K would be warm white lighting, while 5000K would be cool white lighting.

CFL Bases:
The base of the bulb depicts what fitting it pairs with. CFL lamps usually have a Bayonet or Edison base, in various sizes. Bayonet bases are fitted with a push and twist action, while Edison is a screw in base.

Why choose a CFL bulb?
Fluorescent bulbs are designed to be more energy efficient than incandescent or halogen bulbs. They have a very low energy consumption which also saves money on electricity bills, over time.
CFL bulbs have a much longer lifetime too, of up to approximately 10 years. The lifetime of the light bulb will be stated in hours.

What is CFL Equivalent Wattage?
Although CFLs do not use the same technology as incandescent bulbs, they are often given a comparable wattage value. Many people are familiar with the appearance of different wattages, so it provides an easy comparison to the equivalent wattage.
