LED stands for 'light emitting diode'. It is a component that is assembled into a light bulb (or lamp) that emits light by electromagnetic force...in other words a type of electronic light source.

In contrast, earlier technology light bulbs emit light as a result of being heated. These are called 'incandescent' and include halogen and carbon filament light bulbs. The LED uses up to 90% less energy than an incandescent or a halogen bulb of comparable brightness.

How are LED light bulbs different?

LED 's differ from conventional light sources such as the old school incandescent light bulb for several reasons:

Firstly, they will last much longer. Approximately 10 x longer than some incandescent lamps; which is the difference between a light bulb lasting for one or two years or 10 plus years.

How bright is an LED bulb?

If you have looked at the packaging of an LED bulb, it will have a much lower wattage than an incandescent light bulb. This does not mean it will give out a dimmer light, it is because it converts the electricity more efficiently!  A large amount of the energy in a traditional 60w bulb came from the heat given off, so it was wasted energy.
 
For example, our 4W LED mini tube bulb can achieve a light output similar to a 40W incandescent and our pear shaped LED bulb is equivalent to a 50W bulb.
When placing our mini tube next to a 60W incandescent bulb with a comparable brightness (2.2 Kelvins - Very Warm), the LED mini tube looks brighter.
 

 

It is important not confuse 'brightness' with 'wattage'....

The brightness is the amount of lumens a light bulb produces. Lumen level is a metric unit of light measurement.
 
The colour temperature is measured in Kelvins and should be labelled on the packaging. Here at Fritz Fryer, we stock bulbs with a very warm light (2.2K). A cold light, for example, would be approximately 4,000 - 6,000K and a warm/very warm light would be approximately 2,000 - 3,000K.  Many people assume that an LED lamp will be cold and stark (as the earlier models were) and rather ugly.  However improvements in the technology have lead to a dramatic improvement in the design and many 'traditional filament lamp' designs are now available.
 
 
Wattage, as previously indicated, is the amount of electricity a bulb uses and this does not determine the brightness or colour of a light bulb.
 
Choosing the right light bulb for your light fitting is a very personal choice. You may choose a cooler, brighter bulb for task lighting and a warmer, softer bulb for decorative lights and a cosier atmosphere. However, there is no one-fits-all.
